Another first for me recently. I was starting to work with my 1958 Winchester M94 in 30-30 and loaded a few rounds up to see if it had promise.
At the range I fired ten rounds of the Lee 311-90 1R over 5.0 grns Unique to get some Ben's Red distributed through the barrel. Then I had 5 rounds of Lyman 311041 over 25.0 grns H-4895. Both loads stayed under 2" at fifty yds with groups about 8" apart but let me know that an aperature sight is in my future.
The cartridges came out of the box and were fired then went back in the box so when I went to load them I just wiped them off and gave a cursory inspection. During the sizing I thought I heard something rattle in one of the cases and found this gas check.
Gas checks were made by me out of .014" Amerimax in my homemade checkmaker and crimp on snugly. I have been using these for the past several years with no problems. Am still trying to figure out how it came off the base of the bullet when it the seating depth had it in the neck of the case. I have used quite a lot of them in 30-06 with the check below the case neck and have never had any problems. I could see one of these coming off and staying in the case.
Pics of the critter below. The hole is from the decapping pin of course. Only thing out of the ordinary I could see is that there is a little half moon about .015" deep on one side from where I didn't move the strip over far enough when puching the checks. Is it possible that this caused a leak path allowing the gas to get under the check and blow it off?
Sorry for crappy pics.
