Garand Double Firing Incident

Took my Garand out with 3 types of ammo. Greek HXP, Korean PS 2-198 lot, and PS 2-161 lot. The PS 198 made the thing double or bump fire from 3 shooting positions, despite my best efforts not to milk the trigger, from the bench, then from prone, then standing. No pressure signs on the cases, and no split cases or heads or any problems with the brass. Then I shot the Greek HXP and the PS 2-161 and the rifle did just fine, no doubling at all from any position. So obviously I stopped using the PS 198 and am saving that for the 1903 rifle, only have a little of it left. Interesting day at the range.

I had another Garand which I have sold, but that one would shoot the PS 198 all day long with no problems whatsoever. In fact that one digested most of the 400 rds of PS 2-198 lot with no difficulties and fine accuracy.

Sounds like the primer hardness of the Korean is less. Is your firing pin channel clean and dry?

It's not that we're ignoring your question. This thing is hard to troubleshoot unless we're there watching you. It's probably simple but hard to say from here.

No problem, I was not expecting much of a response. It was just interesting that the doubling was clearly related to one lot of ammo, not the trigger, or me, except maybe the recoil was too powerful for me to prevent it from bump firing. The PS 2-98 ammo, only a little remains, will be relegated to 1903 shooting.

If at some point this Garand had some trigger work done it just could be the trigger sear hammer engagement may not be the best. Look at the hammer and see if it has any honing evidence. I had this issue on my M1A.

Just 1903 shooting? A sad waste of resources. Just keep working with this M1 and it will all iron out.

My M1A would do that with one of my triggerhousings. I keep changing out parts until it stopped. It turned out to be a really nice looking, as new M1 SA hammer.

I have 1000s of rounds of Greek HXP ammo, Korean Lot # 2-161, and also various reloads that work GREAT in this Garand. To me the ammo in lot PS 2-198, seemingly hotter than the rest, is the offender, not the rifle. I have very little left, so it gets relegated to the 1903s. I have every intention that the Garand will continue to shoot happily for years. If it starts acting up with the other ammo, then I will definitely start checking the parts.

I think I lucked out with this one. Its a CMP rifle, a Greek return, came to me with a TE and muzzle wear of virtually 0. (It was checked with gages by a guy who has a HUGE Garand exhibit and goes to the collector shows.) I had DGR put a really nice stock on it, & I have Dean's tech inspection report around here somewhere. The thing groups amazingly well with Greek ammo, except there is always one of the 8 rounds outside the group, which could be several things, but it doesn't bother me.
