Trey.... tried to stay away.... subject runs deep.... Marksmanship begins like an Egyptian pyramid, at the base. While the COORDINATIONS of MARKSMANSHIP----the technique of making a shot----pertain to all positions, from sandbag rest to standing, the body’s lack of support separates standing from sandbag (or other rest positions such as Creedmoor and Dead Frog) from prone, sitting, and kneeling. in standing the gun never stops moving. More than any other position, standing demands a smooth squeeze & follow through. This makes standing more susceptible to nerve pressure.
Standing, also called Offhand and the other positions rely on the same grip pressure. Two qualities regulate grip pressure: 1) hand strength, and 2) recoil. I would not pretend to equal Ronnie Wells’ hand strength. My relaxed grip pressure doesn’t not equal Ronnie’s relaxed grip pressure. Too much grip pressure induces muscle tremor. Tremor not only throws the sights around, tremor spreads its spasm to the trigger finger. More shots are lost at the trigger than on the sights. Not only that, spasm on the trigger throws shots farther off target the a faded sight picture.
When wounds, injury, or a medical condition induce acute or chronic tremor to arms or hands, this hybrid rifle-pistol stance may help steady the shot.
Hybrid Standing, two hands * Assume boxer’s stance, quartering toward target. * Shift lead foot a bit more forward. * Pistol held at Low Ready, muzzle angled slightly forward. * Sweep pistol up to target, simultaneously bracing support arm against chest. Elbow anchors arm against chest. * Gun arm, elbow slightly bent, forms a buttstock.
Depending on one’s anatomy, the support elbow may be close to the sternum. Which means the arm is more to front of the rib cage than beside it.
Advantage----steady. Disadvantage----shortest Eye Relief of all standing positions.
Squeeze like you’re taking a baby’s pulse. To shoot faster, take the pulse faster. David Bradshaw

Gunny268.... reckon you now have yourself a shooter. Looks to be good work. Contender may jump in to tell the Super Blackhawk grip frame, hammer & trigger ain’t original to the revolver. A black-anodized aluminum grip frame will restore original configuration and better fit your mini paw.
A diet of .38 Special will accelerate anatomic familiarity.
And remember, the Peacemaker lockwork mandates hammer-down on an empty chamber for holster carry. David Bradshaw

***** This photo translates to a static image the difficulty of hitting a moving target against a cluttered background.... the challenge to bring sights to the eye without the anchor of a buttstock.... a split-second to snap your eye from target to front sight, (with rear sight attached).... while tracking target across a field of visual noise. Camera focused on the background, it nevertheless illuminates difficulty of holding front sight against the kaleidoscope of motion behind it.... then timing squeeze to put the bullet where the target will be when the bullet gets there. Without light on black sights, black sights grow blind on a moving target against a mottled background. The Ronnie Wells/Fermin Garza sight has options of greater versatility than regular irons. Some shooters prefer a wide rear notch to put more light around the front sight. This generally favors speed, and for some shooters plainly makes it easier to read their sight picture. For others, this shooter included, a rear notch which nearly hugs the rear sight flattens the PLANE of the front & rear sight. David Bradshaw

Although I never thought of it as a “rifle/pistol” combo, it proved a smooth coupling of ballistic talents----my old dog leg Ruger Model 77 6mm Remington with Leupold Vari-X II 2-7x Duplex, and my seminal S&W M-29 .44 Mag 6-1/2”; two phenomenal wands in ascending marksmanship. David Bradshaw

Stan.... thanks for your photos. My imagined image of the Charter Arms ACP extractor pictures a round wire spring, pushed in by the bullet nose as the chambers are charged, to snap into the extractor groove.... Rimless case headspaced against a thin, square step to exit hole (throat). Your Bulldog .45 ACP extractor looks complex.
Handled the S&W 9mm revolver in the factory as the model was about to be released.
Outside the U.S., the 9mm Luger was much more widely distributed than any American handgun round. Sturm, Ruger and S&W responded to foreign requests for service revolvers chamber the 9mm. The S&W system struck me as serious and complex, with sharp little teeth to hook the rimless rim. I don’t recall a a provision for half-moon or moon clips in these revolvers. David Bradshaw

A friend, who often packs a S&W M-696 L frame 5-shot .44 Special, asked whether I have any dope on the Charter Arms Bulldog .45 ACP with ring-spring extractor. As my experience is limited to the early Bulldog in .44 Special (with wrap around wood grips which stung the base of my thumb), told him I’d have to asked around.... David Bradshaw

***** wheelnut.... many IHMSA silhouette matches and an assortment of championships have been settled by Smith &wesson Model 29’s and Ruger Super Blackhawks shooting the Sierra .4295 240 JHC and Hornady .430 240 JHP through chamber exit holes in the .432-inch zone. To be match accurate, a harmony must be struck between the revolver’s vital dimensions. If your BFR .44 Mag with .430” throats prints .431” bullets tight, but poorly with .429’s, first place I’d look is GROOVE DIAMETER. Then I’d name exact bullets which shoot straight, and iname bullets which shoot poorly. Accuracy, in order of importance1) Revolver. 2) Bullet. 3) Load. David Bradshaw Very interesting... The Sierra .4295 240 JHC shot 1.3 - 1.6 inch groups at 25 yards, the 240gr Hornaday XTP tightened down to .6-.75 inch groups with .431 240 GR JSP Bullets from Roze Distribution shot the best at .4 - .6 inches. Regarding the Sierra's, these bullets have been excellent in my Super Blackhawk, Model 629 and new Anaconda so the lack of performance in the BFR was surprising. ***** wheelnut... probably no revolver bullet proved itself more accurate through top flight competition than the Sierra .4295 240 Jacketed Hollow Cavity (JHC) in mowing down steel. From local matches, to state, to regional, to international, the Sierra 240 JHC wrote sharpshooting through the barrels of Ruger, Smith & Wesson, Dan Wesson, Seville, and Freedom Arms. Trophies earned through the pony express broach and button rifled barrels. Good as the Sierra is, it can’t podium through a dimensionally inferior barrel. At the same time, the accuracy of a brilliant barrel is doomed when the person in charge of the forcing cone doesn’t understand the technique. David Bradshaw

I will look into the firing pin issues. Thanks. I am wanting one in 10mm also! First one I see is coming home. I really think the barrel on this 44 is the issue. Cant prove it yet, but it is my main suspect. ***** Trey.... yes, leads point to barrel & forcing cone. Note in your cover letter the ammo----factory & handload----you’ve piped down the barrel. Sounds like Uberti added a new definition to “floating firing pin.” Firing pin slides in hammer. A pull of the trigger lifts pushrod in hammer.... pushing firing pin forward.... David Bradshaw

It has throats of .431 what diameter bullets are you feeding it? I have a BFR with .430 throats and .431 bullets shoot extremely well, some .430's are good and all .429's have been poor. ***** wheelnut.... many IHMSA silhouette matches and an assortment of championships have been settled by Smith &wesson Model 29’s and Ruger Super Blackhawks shooting the Sierra .4295 240 JHC and Hornady .430 240 JHP through chamber exit holes in the .432-inch zone.

Some time ago I told yall how I love my new Uberti Bad Boy 44 Mag. Well, I am starting to have problems. Firstly, I cannot find a load factory or handload that shoots well in this weapon. 4 to 5 inch groups at 30 yards. I have tried loads from "rocks and dynamite" to powder puff loads. Bullets from 180 grains to 310. Nothing groups well. Second, accuracy is not good enough for my wishes. Which puzzles me; every measurement on this weapon is spot on (or seems to be). Throats are .431 best I can measure. Barrel slugs .430. No tight spots, but the forcing cone is DEEP. Think "Taylor Throated" or "Weatherby throat". The rifling is crisp and sharp though. The crown seems smooth and even. The barrel is "over cocked" which makes it shoot slightly to the right but with adjustable sights that can be overlooked. Third, a recent development, it has started to misfire. This being a three notch cocking system (which I know absolutely nothing about) I was told there was a piece of metal that backs the firing pin when the trigger is pulled making it safe to carry 6 rounds. Well it aint working. The misfire does not follow one particular chamber. Might misfire at any time. The importer here in Texas told me to send it in but dang I hate doing that. I am sure they wont replace the firearm with another proper one, they will just fix the misfire since it does "function" as a useable firearm. I have been shooting every load I can find or make. Standing, sitting, Creedmoor, supported, unsupported, everything but closing my eyes. Even had my wife load the cylinder with empty and loaded cases and spin the cylinder to see if I was flinching. The grip fits me better than the stock new Ruger grip and I love the weapon but if it doesn't shoot well what are my choices? ***** Trey.... the short list of dimensions you illuminate condemns the forcing cone. As you know, I disdain a deep forcing cone. There are exceptions, demonstrable only in detail. Missing from your list: * bore & groove----uniformity. * forcing cone----alignment with bore; smooth or rough. * chamber-to-bore aligment----chamber axis vs bore axis: runout & longitudinal. Revolver accuracy is an orchestra of dimensions Within this concert, some dimensions are more important than others. The balance of a perfect bullet, thrown off balance before it seats in the rifling, cannot be saved by a perfect bore & groove. Of course, damaged bullet balance worsens in a wavy bore, or bore with loose groove diameter. Forcing cone diseaseEnough over-excited handloading accompanied the Magnum craze of the 1960’s into the 1980’s to provoke SPITTING (sideblast of propellant & bullet particles from cylinder/barrel gap) to get the attention of manufacturers. A expedient “cure" was introduced----the deep forcing cone. S&W, Sturm, Ruger, and other magnum makers adopted the remedy without accuracy analysis. The disease persist some forty years later, albeit with lapses back to sanity vis the traditional modest forcing cones. By dint of the competitive firing line, this shooter happened to be on the ground floor of articulating the problem. Still, despite the soaring growth of Handgun Silhouette, too many in manufacturing regarded long range revolver marksmanship as exotic. The proper cure is to consider the FORCING CONE as absolutely critical to accuracy, to show it utmost respect in the first place. (The same is true for LEADE in a centerfire rifle.) Providing bore & groove dimensions are sound, a bad forcing cone can be remedied by trimming BARREL FACE and SHOULDER enough to turn a concentric short cone the good barrel. In the prices trimming BARREL SHOULDER at achieve proper THREAD TIMING. My preference is for the barrel to hand tighten 10 to 12-degrees BTDC (Before Top Dead Center). Barrel/frame alignmentIf the barrel socket in the frame is crooked, the manufacturing remedy is to replace the frame. At the gunsmith level, surgery may or may not save it. A tenon crooked on the barrel will require shortening breech end of barrel up to an inch to cut a new tenon. David Bradshaw

Apply gc and size before or after? Concerned that if I powder coat before I apply gas checks and size the paint will come off in th process. The gas checks are a tight fit to start. Mold throws at .412 , I size to .410 ***** foxtrapper.... contender and boatswainsmate are correct. The first batch of the Bradshaw-Martin .357 194 SWC Gas Check bullets cast by Lee----in the bullet's first mold (Dan, now retired, @ Mountain Molds----had some gas checks fall off of em in shipping. These bullets I set aside for targeting @ 100 yards. Reset gas checks by hand and deep seated the 104 grain semi wad cutters one 18.5/H4227 in Remington .357 Maximum 1.605” brass with small rifle primer. My best groups sandbag 5x5 around 2-inches from stock Ruger with 10-1/2” Blackhawk Maximum. Bradshaw-Martins 194’s recovered from penetration through water jugs retained gas check. Likewise, bullets which zippered through snow and grass. My little experiment with gas checks slightly crooked on the heal of the bullet at the start of seating suggests that firing fully seats the gas check. Make sure edge of gas check doesn’t catch on heal of bullet. David Bradshaw

Pete.... Bill Ruger liked to make one parts serve two jobs, an engineering concept invented long before John Moses Browning or Bill Ruger put it to use. Couple of examples on the New Model * BASE PIN spring loads transfer bar while serving as cylinder. axle. * LOADING GATE swings open to load/unload, simultaneously "locks" transfer bar. * TRANSFER BAR enables hammer ro strike firing pin (when hammer is cocked and trigger is pulled). Transfer bar & loading gate form heart of the passive safety.. * LOADING GATE SPRING holds gate closed, and when open. As gate is opened, gate spring depresses bolt to allow cylinder rotation from loading/unloading. Gate spring also secures trigger pin.
Since hammer cannot be cocked while trigger is blocked, revolver cannot be fired during load/unload sequence.
With revolver at rest, hammer does not reach firing pin.Ipening the loading gates locks the lockwork. Loading & unloading are accomplished WITHOUT TOUCHING HAMMER or TRIGGER. By definition, a PASSIVE SAFETY system. David Bradshaw

Benjamin.... a few notes on the Browning 1926, aka Pistole 35, aka Hi Power, aka High Power.
Magazine safety Logic behind magazine safety probably originates with an agency issuing the pistol in an unfireable state. Allowing gun to be shot only with issuance of magazine. Curious, the same mentality never spread to rifles.
Magazine safety is deactivated by removing pin in trigger which holds a spring-loaded plunger. Insertion of magazine depresses plunger. Plunger rotates a “push rod” into alignment with a rocker arm pinned to the slide. As trigger is squeezed, “connect rod” pushes forward end of rocker arm... causing rearward end of rocker arm to depress SEAR... causing HAMMER fall.
Removal of magazine safety eliminates drag of plunger on magazine, which instantly smoothes & lightens take-up.
Burr hammer vs spur hammer The Browning P-35 continues the too-short tang of Browning’s original 1911. The short tang 1911 was corrected on the 1911-A1 by incorporating a longer tang on the grip safety. Such improvement must be incorporated in the frame on the P-35. I get hammer bite from the original 1911, and hammer bite from the original P-35 with burr hammer. The spur hammer saves me from hammer bite. Unlike the 1911, which is beautiful with burr hammer and with spur hammer, the P-35 is much more attractive with burr hammer.
Magazine catch The P-35 probably represents this first pistol made with an extended magazine catch. This works fine for speed loading, yet its high button on the double column grip exposes the magazine to accidental release. Which I’ve experienced with naked carry, Canadian military canvas holsters, and holsters which put leather in contact with the catch. That result can turn the P-35 into a single shot (proving the mag safety has been removed and the pistol has a round in the spout.
Accuracy Depends on the gun. I’ve had a Browning Hi Power which was wonderfully accurate, and a later one which was mediocre. When Bill Ruger developed his centerfire auto pistol, he gathered representatives of 9mm Luger pistols. He asked me to try some of them during breaks from shooting .357 Maximums. There was no Ruger 9mm to try at that time. Up on the hill behind the houses of Bill and Bill, Jr., there swung a rack of steel plates, some of which were six or 8-inch squares. I could pelt these with regularity from my Browning. Some 9mm’s, and an inaccurate Browning, would not do so. A Walther P5 with amazing ergonomics----which retailed from Interarms at an astronomic $960----did miserable against the plates @ 50 yards.
The SIG/Sauer P225 (aka P6) wasn’t available, nor its followup P226. Nor was the the HK P7, which I later found to be exceptionally accurate, with a super trigger, yet plagued by a noisy squeeze-cocker firing system which contradicts flex-reflex of the human hand. The SIG/Sauer P225 (single stack 9mm) and P226 (double stack 9mm) would prove exceptional accuracy.
Bill Ruger was most concerned with durability and reliability, and thinking along the lines of “service accuracy.”
Sweat & corrosion Bluing of carbon steel affords poor protection against humidity & heat, especially perspiration, which varies greatly from individual to individual. I am low on the acidic scale, yet Meixcan carry has shown nascent rust on a Browning Hi Power and a SIG/Sauer P226 in less than a day. Freezing cold impedes oxidation, but who carries next their skin in cold?
Bluing on bead blast shows rust faster than bluing on high polish.
Mexican carry A pistol with a flat, not fat, slide rides better, of which the 1911 and Hi Power are prime examples. Naked carry will never be as secure as a proper holster. My Chic Gaylord inside-the-pants scabbard for the 1911, made around 1960 of very thin pigskin, retains its integrity all these years later. Pigskin can be skipped thin while retaining strength, but, as Snyd on Singleactions has observed, has become hard to find these days. Unlike deerskin, which is great for shooting gloves, pigskin is great for shooting gloves and inside tnside-the-pants leather.
For this shooter, Mexican carry is for immediate action, not steady carry.
Small of back Should be limited to the most immediate of immediate actions. I wouldn’t want to be caught wounded while carrying in small of back. Which is to say, one fall on the backside stands ton wreak havoc on the spine. I shun any carry which places the handgun on bone. David Bradshaw
