Charles.... perhaps the Bates Motel has video. Trust you’re able to get this horror squared away.
As to Ye Old Equipment Check, Lee’s bench rest pedestal, etc...
Years ago, before Lee Jurras lashed together America’s inaugural HANDGUN SILHOUETTE match in 1975, this shooter was at work with his SAKO L61 .338 Winchester Magnum, stoked with the Sierra 250 Boattail Spitzer long-seated over 70/IMR 4350 for 2,800 fps in Winchester brass with CCI 250 mag primer, the marksman noticed from this basically inert rifle a barely discernible creep in Point of Impact. The Leupold 4x scope itself is a pretty staid piece of equipment. The rifle had a total of 600 rounds through it, considering its generous bore a very low round count. The target refused to lie. Dry fire revealed the Duplex reticle as steady as pig iron.
A close look revealed the rifle was working to recoil out from under the scope. The SAKO receiver has tapered dovetails cut into ring and bridge, against which scope bases jam----tighten----under recoil. Pricey SAKO mounts failed early in the life of the rifle, long since replaced by superior Redfield bases. The problem lay, or slid, with the Redfield windage screws on the rear base, against recoil a weak arrangement. We’ve seen this caper many times. Windage screws on the rear base help to ZERO a rifle while keeping the reticle/erector tube mechanically centered in the scope tube. A rifle should shoot close to the scope with the reticle at the center of its adjustment. This provides light waves the straightest shot to your eye. When scope and rifle dos not align, sighting-in forces the target to make a dogleg from objective tube through erector to ocular lens.
Distortion wasn’t the problem on the SAKO .338; the problem was a mount/ring too weak for the job. The lesson reinforced the need for regular equipment checks. (Later on Bill Mading TIG welded the ring to the base.) The lesson reinforced the need for a regular EQUIPMENT CHECK. Those who learn sharpshooting discipline get used to cleaning their handguns & rifles. Cleaning affords the opportunity to check sight adjustments, lubricate vitals, and to check screws.
A casual shooter is neither bench rest shooter, high power rifleman or riflewoman, silhouetter, practical shooter, nor hard-corps competitor of any kind and wouldn’t notice a loose screw on a firearm until after it falls out. Not to mention a loose bench rest pedestal. So this is another lesson from Lee, not only to himself but to all of us. EQUIPMENT CHECK.

How right you are Mr. Bradshaw. I have gotten to the routine of checking the screws on nearly every handgun I shoot. Heavy loads seem to shake the screw loose on the EJH. Loc-tite should cure this. I could not agree more about keeping lubrication in the right places.
Having to deal with shakey rifles or sights well I have had a small share in this. I had a weaver scope internally move on me and the next thing I notice the windage turret came off. On a different occasion I went to a shooting range and was preparing for my shot when I noticed something moved . I started looking and realized that the benches were all connected. This does not work well with wood. Each shot from a high powered rifle shoot the bench up and down the line. I politely removed myself from the premises. You see sometimes in my travels I get to stop in at different places and shoot. I do not know where I fit into this at times, but I keep learning and striving to improve with each outing. But I can sympathize with Lee when bewilderment takes over and drowns logic. It sometimes is difficult to quickly analyze or troubleshoot problems. Especially when you are on a line competing. As you have said several times, a good spotter can be worth their weight in gold. And sometimes an extra set of eyes or a clear, fresh, relaxed mind can really help. We learn from Lee just about as much as he learns sometimes. I know I have. Excellent reminder Mr. Bradshaw, thank you.

"...After a month of diagnosis, the problem was a loose rest..."
You are a better man than I. I would have been seriously cussing myself.

"...After a month of diagnosis, the problem was a loose rest..." You are a better man than I. I would have been seriously cussing myself. Trust me, there was a lot of cussing. Cutting 4-something groups in a regional NBRSA match wasn't fun. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Benchrest History – Volume 4 ____________________________________________ I bought a nice piece of benchrest history at the Roanoke match. Longtime, and pretty renowned, BR shooter Ted Manning was selling his Culver powder measure. Ted started in the game around 1960 and kept at it until cancer sidelined him a few years back. Fortunately, Ted is beating the cancer. We talked about Culver since the two competed alongside each other for decades. He seemed glad the measure was going to someone with a connection to their history. After almost 50 years of use, I decided to freshen the exterior. As purchased:  I cleaned the excess JB Weld that holds the bottle adaptor to the main housing. I also filled some of the casting imperfections, lightly shined the brass insert, and painted the Lyman hopper.    Related, here’s the first article written on a Culver measure from 1953. To this day, benchresters use the same design as made by Linwood Harrell and Neil Jones.   -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Match #10 – VFS, 100 Yards _______________________________ Hard to believe this is my 10th match since starting to compete last July. Saturday was rainy but showed moderate wind. All in all, it was a good day to shoot. I was exhausted, having logged 80+ work hours the week prior. With little sleep, my concentration wasn’t the best but you can always find some excuse. Part of competition is one’s ability to push through. I dropped two points overall, and against a cast of veterans, that put me towards the bottom. Bull #2 gave me fits throughout and that’s where the 9’s landed. I suspect my bag set-up may be off for score. McMillan Edge stocks are known to be sidewall sensitive on bag pressure. For group I use light tension but it still may be too much for score. Unlike group, where the gun is set to the same location, VFS makes you move all over the target. One of the top shooters at the event recommended I lessen the front grab going forward. This may reduce any stock binding that occurs upon horizontal movement. I’ll fiddle with this when practicing on Saturday. You know you're facing a tough crowd when the top two finish 250-23X.  I narrowly missed 6 or 7 X’s, many of which would’ve been hits with a 30-cal. At 200 yards, the 6mm isn’t at much of a disadvantage. On 100 yard VFS, the gap is pronounced. Either way, I need to shoot more score targets. The transition from group to score is wider than I expected. I had a lot of what you see below Saturday. It’s harder to get these than it may appear. The dot is just 0.0625” in diameter. Clearly, a .30-cal would’ve scored an X.  The gun could not be blamed for how I placed. I finished the last target in 4 minutes with shells left in the block. Running five as fast as I could on a sighter bull netted a 0.186”. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Congrats on the Culver powder throw. Nice snag. Lee that is some mighty fine shooting even if you didn't win 1st place. I would like to see you shoot a 30 cal. The way that you and your Dad build guns I think you would jump in the rankings.

I would like to see you shoot a 30 cal. The way that you and your Dad build guns I think you would jump in the rankings. Charles Charles – the plan is still to shoot .30-cal for score and 6 PPC for group. I’m just waiting on the Lederer 30 blank. The reamer is done:  I may call Lester Bruno and order a 1:17 or 1:18 HV Krieger. He usually has them in stock. I’m eager to try Lederer’s work, but the wait it killing me. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

This sounds like a real Plan. I am eager to see the results on this too.

Any thoughts on Schneider barrels? Supposedly he makes the barrels for the M40.

Any thoughts on Schneider barrels? Supposedly he makes the barrels for the M40. Gary’s barrels aren’t used much in point blank benchrest. They were more common in the 1990’s. But he produces very high quality blanks. My dad has a Schneider on his .25 Dart heavy varmint rig. Even with limited bullet selection, it’s a consistent 1/4 MOA gun. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

New Front Rest ________________________ When I returned to benchrest in 2013, I needed a front rest. There are basically two styles to choose from. The “knob” driven, as I call them, or the joystick operated. I had little to no experience with either. In the 80’s and 90’s I was a bag squeezer, meaning I adjusted for windage and elevation at the rear. Dad and I shot soft rear bags that we pinched in conjunction with the lower angle of the butt stock. Sounds primitive, but some of the best in the game started that way. Having never tried a joystick, I opted for a Sinclair competition model four years ago. They’re stable at thirty pounds and employ a speed screw for elevation and a fine adjustment knob for windage. Here are some photos of that rest. These retail for just under $800 and function beautifully.    Fore-end stop with Velcro added to cushion the stock. In theory, this should reduce vibrational influences when pinning.  I’ve shot tiny groups off this thing, but want to increase overall speed. Dropping to the sighter, taking a shot, and getting back to the record involves dialing two knobs. When conditions change rapidly, I often miss the window by a second or two. A lot of guys I shoot with recommend joysticks for speed, especially when moving around score targets. So I took the plunge and bought a Farley Co-Axial.    The Farley is very easy to operate. First photo - the long handle allows you to move the top over 360 degrees. The left knob adjusts bag tension while the big knob on the right sets overall height. The diagonal handle locks the top on the main post. Farleys are well engineered and weigh 30 pounds. Even so, there are some common upgrades that’ll improve their performance. They are as follows: 1) The joystick boot tends to bind at full travel and even limits total adjustment. I disconnected mine from the locking ring, but left it loose to prevent dust from getting to the internals. 2) The leg points don’t mate with conventional Stable-Feet. I swapped out the factories for a set of PMA stainless legs. 3) The front bag doesn’t hold form well and wrinkles on the main bearing surface. I installed an Edgewood Cordura, filled with normal playground sand. 4) Like the Sinclair, I added Velcro to the fore-end stop PMA leg upgrade:  The Edgewood bag is shown below. This is the standard version, not the reinforced model with the hard leather insert. From what I’m told, the reinforced can introduce vertical. The regular bag is what most folks use.  I also purchased Farley’s hard carrying case, bringing the total to $1,250. Not cheap, but it's already paying dividends.    In my last score match I shot the Sinclair and missed some conditions. Had I been able to get around the target quicker, I may have increased the X count. The past two weekends I’ve practiced with the Farley. Not only have I navigated my POA faster, my X counts have increased. Two 50-5X targets shot back-to-back. The rest of the day I was landing 50-4X’s and 50-3X’s.   The Farley sees its first competition this weekend (VFS-100 in Black Creek, Virginia). -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Wow The targets are looking really good. I am sure there is going to be some good results the next sanctioned shoot. The Farley is fine equipment and even the carrying case is awesome. I look forward to the next shoot. Great info about the Farley, and I tip my hat to the improvements.
