Differences in .22 barrels Empty Differences in .22 barrels

Post by Jerry Keefer Wed Dec 30, 2015 11:11 am

I posted this some time ago.. I received a request to repost it.. My photo bucket account had filled to capacity, and I deleted many many  photos..I guess this 22 topic was deleted..I found and included some photos of the upgrade of Marvel/AA conversions to Lothar Walther match .22 barrels, and threaded breechblocks.  Fortunately the camera card and thumb drives hold a nearly unimaginable number of photos.Smile It became a daily effort to stay ahead of the maximum allowable photos, so I broke down and paid Photo Bucket the annual fee to maintain more photos.. Good for a couple more thousand..SmileSmile
OK.. Follow the red arrows..Bottom right: S&W 41 shows a small dimple from a stamped letter on the bottom. The heavy land to groove ratio and the tight bore is visually less apparent.
Bottom left: A High Standard barrel shows an excellent well defined chamber, but the barrel  locking lug drill almost entered the chamber. Nice smooth gentle leade angle
Center right: narrow section of a S&W 41 which shows distinct variations in bore dimension..(Shadows)
Upper left: Another 41 with a poorly cut chamber face, and an abrupt 5 degree leade angle . The radius extractor relief is very easy o see, and visualize/imagine the extractor problems these cuts can cause.
Top center: Not as defined as I would have liked.. Ruger no distinct chamber at all.. Just a hole. Rugers are testimony to the inherent accuracy of the 22 cartridge.
Top right is a Lothar Walther stub I tried to show, but it blurred on me..The fine precise rifling and low land to groove ratio  is apparent.. I  may try to dig that piece up and take the pic again.

Posting pictures of a conversion Dave Wilson did for me. He manufactured a breech block out of A10 tool steel and used a Lilja undersize bore barrel.

Dan Lilja probably makes the best 22 blank on the planet.. I used his 22 blanks for making 41 barrels from scratch... Every one of them shot great..

Hi Jerry,
The Lilja was an experiment and Dave was nice enough to make it. Just adding to your thread for others, hope you don't mind. Smile
I had a senior moment and forgot where I put the silver solder (rearranged my shop) and still need to ultra sonic clean it, but it's on the way Saturday.
