Markbo.... Dick Casull configured the grip on his revolver to his hand. Considering the rocks & dynamite he loaded, I rather doubt he'd want to paw a Pachmayr. Dick may have cracked my middle finger with one of his blue pills. Probably a .454 case mounded over with H110, brushed level with a poker card, with the bullet seated in a arbor press.

paul105.... appreciate your posting photo of your Model 97 pocket revolver. Three questions: a) Can you pull the cylinder without first removing the ejector housing? If not, perhaps a ring-type button could be fashioned, which would allow the ejector button to override the cylinder pin. b) Does bullet blowback throw fouling on your objective lens? c) Are those Weaver 4x4 rings? How well are they holding up? David Bradshaw David, Freedom Arms has a modified ejector tab that allows removal of the base pin and cylinder without removing the ejector rod housing. Boge Quinn did a write up here: gunblast.com/Boge_Freedom97.htm -- the series of pictures in the right column show the FA modification. I didn’t notice any blowback on the objective lens. Yes, Weaver 4x4 rings. I have them on the 2x Leup shown above and on a 4x Leup. I use both scopes predominantly for load development/testing. I have used both scopes w/4x4 rings on FAs in .454, .475, and 500 JRH. So far no problems, however I have not shot a significant round count using any of these rigs. The little M97 now wears iron sights and the .45 ACP aux cylinder – it’s a ton of fun setup this way. Paul |

David Bradshaw I know cracked bones aren't funny but WOW!  And before I forget (again), many thanks for the informative pics and information! |

Seems like the scoped, short barreled revolver is another misunderstood handgun. I’ve posted the following picture before, and it usually draws some humorous comments. In reality this 3 1/2” round butt, .45 Colt FA97 scoped with a Leupold 2x is powerful, accurate, portable and easy/fun to shoot. It weighs less than an unscoped 4 5/8” FA83 and 300gr/335grs at 1,100 fps should handle most anything encountered in the L48.  My preference is 4-5" barrels but THAT is a looker and really does something for me! No objection to scopes either!  |

tek4260.... in some environments, H110 does not need to be load at 100% density (no air space) for excellent accuracy and low deviation velocity. With Leupold 4x mounted, my old nickel M-29 8-3/8" prints the old, pre-XTP Hornady 200 JHP over 22/H110 into 2" @ 100 yards. Same charge under the pre-XTP Hornady 240 JHP also shoots beautifully, and both take whitetails cleanly. ( Have only taken lung shots with the 200 JHP.) One of above photos shows the cast 335 LFN GC deep seated over 19/H110, which leaves a thin slice of air space. Accuracy, consistency, and velocity just a hair below 20/H110 load. Hodgdon HS-6 has been a supreme medium burn powder for decades in a variety of pistol cases, with generally fine accuracy spanning light to heavy bullets. It seems that the grip afforded by deep seating imparts a moment of hold-back that improves ignition of H110 under the lead bullet. With conventional seating, ignition and burn improves from a full dose of H110. Heavy dose of Win 680 imparts a push to recoil----the above load noticeably consistent. Yet, despite the good result, I consider this an experimental load. David Bradshaw Makes perfect sense. Most people want a bullet that pushes through the throat with finger pressure, whereas I like mine .001 or more over throats to give the same result as deep seating. Also, on those rubber grips, how do y'all keep them from busting open along the backstrap? A friend of mine cannot keep them on his 500. Heavy loads and a stout grip are more than they are up to. |

tek4260.... haven't tried Pachmayr on the .500. Have heard the rubber tears palm or web meat on some shooters. Perhaps custom scales that protect middle finger from the trigger guard would work. And, as you observe, excellent accuracy comes from some revolvers with tight chamber exits. However, this arrangement is more apt to lead. We had spectacular accuracy with jacketed bullets in some tight-throat Dan Wessons.

That is the reason the 45's all get .4525 throat reaming and shoot .453-.454 bullets.
I actually want to start with the revolver with the tightest throats, then ream to ensure they are over bore diameter, thus no leading problems. The swaging down in the throats at firing negates any variation in case neck tension or crimp.
My belief my be unfounded, but I believe that the reamers are "in spec" when they are new and as they wear, get smaller. So if you get a revolver with tight throats, the chambers will be tight as well. You can then ream the throats and have a better cylinder in the end than if you got one with proper throats to begin with.

In shooting the cast .452" 335 LFN GC for Vol. XL, three bullets measured .454". These .454-inch slugs----which I think Brinnel around 18----would have to be hammered through FA M83 throats; thumb pressure wouldn't come close. Loaded these oversize slugs, deep seating over 20 gr./H110. As I recall, velocity averaged 1110 fps on the Oehler 35P, with 2 fps extreme spread. Group, off the bag, 4" @ 100 yards. The deep seated .454's chambered in the Freedom Arms M83 without friction.
Pressure with slightly oversize bullets usually isn't a problem, as long as the case isn't pinched between bullet and chamber. At all hazards, I want a round to chamber freely. When loading a single or double action revolver, intuition & habit dictate cylinder shall be spun in frame. Any round which hangs up is removed before gun is holstered, carried, or shot. Technique likewise discovers grit under DA extractor, high primer, burr on case, etc.

Scoped Blackhawks to have their place in the order of things. I had this one build mainly for hunting antelope. Alan Harton replicated the Freedom Arms top strap so I can use either the Freedom Arms rear sight or more importantly a black coated Freedom Arms Lovell scope mount for the Leupold scope.   |

I already had the pieces here and there - just had to put it together. I love lazy Sunday mornings! It is a .357/.38/9mm Blackhawk on a 2x Leupy scope and mounts that wil be seeing a lot of plinking!  |
