Charlie Harley, #14153 Posted April 9, 2020 Share Posted April 9, 2020 I have a Garand that hasn’t been shot in about two decades. Took it to the range today with some 20 year old reloads that were based on an M2 ball duplication load, the details of which were lost in a notebook during one of my many moves. After maybe five Pings, I had a misfire. Pulling the round, it appears that the previous round had the neck separate and stay in the camber. The next round entered the chamber but couldn’t fully seat, causing the light strike. Very lucky indeed! After gathering the empties, I noticed that more than half the necks showed cracking and partial separation. These were all loaded using once fired Lake City national match brass. Any guesses what might might have happened? Link to comment Share on other sites More sharing options...
Capt. James H. Callahan Posted April 9, 2020 Share Posted April 9, 2020 That's really weird. What year? If it's LC I wouldn't think it would have ever been corrosive primed. JHC Link to comment Share on other sites More sharing options...
JD Lud Posted April 9, 2020 Share Posted April 9, 2020 Brass can harden with age making it brittle in some cases. Some will say it doesn’t but google and will find many situations very similar. Link to comment Share on other sites More sharing options...
G W Wade Posted April 9, 2020 Share Posted April 9, 2020 Just read a posting elsewhere, that sounded very similar. The author was talking about old rounds corroding between the case neck and bullet causing severe pressure spikes. You mentioned it hadn't been fired in a long time and guessing reloads were same vintage. He suggested putting the rounds ito your seating die , then bump the bullet in slightly to break the tension between the case and bullet. Simple to try Good Luck GW Link to comment Share on other sites More sharing options...

Annealing the necks might cure it. Could be powder deterioration causing corrosion https://thefiringline.com/forums/showthread.php?t=581789 Link to comment Share on other sites More sharing options...

I has half expecting POOF. Nope, that stuff was hot as Hell's doorknob, d*mn near kick your teeth loose! JHC Link to comment Share on other sites More sharing options...
Imis Twohofon,SASS # 46646 Posted April 9, 2020 Share Posted April 9, 2020 Im thinking corrosion from dissimilar metals. I would try pulling a couple of bullets and inspect the cases and bullets. If they are extremely difficult to pull it may indicate corrosion sticking the bullets, resulting in high and/or inconsistent pressures. Might be time to dump that bunch of rounds.

Pat Riot Posted April 9, 2020 Share Posted April 9, 2020 I had the exact same thing happen years ago.. It was old Lake City ammunition, not reloads. I think UB is correct. Powder deterioration causing problems. I hope that cartridge neck stuck in your chamber was easy to remove. I had one heckuva time getting one out of my chamber.

I was the one who fired it the first time at DCM matches in the 70s and 80s. My youth was very well spent. :-) Link to comment Share on other sites More sharing options...
