From an engineering stand point, all fasteners have a torque limit rating. If I have a pet peeve, it is tightening the side plates screws TOO tight.. There is very little reason to over tighen these screws, or to use any form of loc tite on them..Snug is a good rule of thumb.. Enough to seat...

Heavy clouds and rain block my sattelite signal.. Sorry for the late reply.. Hamden; Camout is a term that describes the effect upon the extractor by the radius machined into the breechface of the barrel. It pushes or cams the extractor away from the base of the cartridge at lock up..The timing...

Hello Jack; The first thing I would check is extractor timing, and, or cam out. The clearance and cam out radius cut for the extractor, varies from gun to gun, (barrel to barrel) and can have a significant influence on reliability. I am ashamed to admit, I struggled with this problem for years...

SS.. Really good .22s will drop down into a 1/2 inch or less at 50. Eley red box is the best, if you are serious about the best possible accuracy. The tightest shooting barrels I have found are those which are relined. Lothar Walther liners are superb... Machined barrels induce unnecessary...

I know that most folks on this forum are general use shooters, but for informational purposes, for the small minority that might be interested.. Tens of thousands of rounds of Eley are fired in target pistols annually. I concentrate solely on BE guns and consume a fair amount in testing alone...

Frozen plunger/spring Ace; You won't like this remedy, but I have been successful removing these, by setting the slide up and boring a small hole at 45 degrees to the plunger bore. I then fish a small wire thru and push the plunger and spring out..if the slide is a pristine safe queen, the...

The extractor tension is a consideration, and should be checked and adjusted.. The sited article on extractors, is incorrect in my opinion. I do not advocate bending the extractor. Bending adversely changes the cam out timing, which is a compromise on stock barrels to begin with...a mire .022 +-...

Cholla & Jeff; Thank you both for the compliments. That fixture is 1-1/4 inch blanchard ground 4140. The sides(edges) are ground and trued so it can be rotated and still be square. The opposite side is set up in similar fashion for machining operations on 1911 frames. The frames are supported by...

Revolver milling fixture Kend; I designed this one years ago. It has served me well. Holding by the barrel is quite risky; it makes it difficult to get an accurate reapeatable, rigid set up. Jerry

Dan; It tightens directly on the insert. I've used mine almost daily at times, for many years, with no ill effects to the inserts. I've had a number of contraptions, this one is the best I've used.. Jerry

gaucho; You can..depending on your skill level, and the equipment you have available. I usually leave the barrel tenon long and reface the cylinder to fit by surface grinding. The process gives you excellent control of the end gap, and insures the cylinder face is perfectly square to the barrel...

Good luck Jerry

Hello Sir; Your question is one that I pursued extensively for many years. In brief, the best ever groups I achieved were with a Kreiger 1-12 twist barrel. I built four guns from that blank, and all four would shoot well under an inch at 50 yards. I have also been able to get very close to that...
