The US Civilian Marksmanship Program used to have it made up in special boxes just for their yearly GarandMatch. I bought a lot of it so I could get really good zeros before leaving for Camp Perry. It was not particularly accurate, but I heard no complaints about it. It was much more accurate than late 1960's US GI Ball, and had no problems with duds. Comparing different lots produced in different years, my Garands put it within an inch or two of other years. I also shot it through several 1903 Springfield rifles, with no difficulty extracting it.
I saw this advertisement from Hornady yesterday:
Hornady
I am wondering if the US Civilian Marksmanship Program is going to use the Hornady stuff, instead of the Greek-made M2 ball that they have been using the past several years. The Greek stuff shot about the same as the Federal stuff, but I had severe trouble extracting the Greek stuff from manually-operated 1903 rifles. I had no extraction troubles in Garands with the Greek stuff, and no torn rims either.
Years ago I shot some commercial .30-'06 through a Garand. The ammo companies are trying for better ballistics than the cartridge gave in 1938, because this is a selling point. The only way to do that is to use powders that produce a longer pressure curve, which results in higher pressures at the gas port near the muzzle. It clearly did not like it: operation of the action was much more violent, brass thrown much harder & further. I won't do that again.
I have no experience with the PMC.
