Avoid.Is the 145gr FMJ Wolf WPA Polyformance Ammo safe to use in the M1A ? I've read pros and cons . I guess maybe bringing along the old bore brush and ratchet it a few times would not hurt . I know it's got a reputation for being a little dirty .
Makes sense.Steel cases don't shrink release from the chamber as easily as brass. My PTR HK style says in the manual that steel case is fine. Probably because the chamber grooves help release it.
Took your advise TheShooter . Going to break it in with some
I agree on the chamber being harder of the two but I always recall this Lucky Gunner article about M4-types and steel case (lots of pictures so it held my interest ICONEEK). For me it was like seeing the movie Jaws and then going to the beach. I have flashbacks to the LG article whenever I hear of steel case ammo in a high end or accurate gun. Granted the article is about some abusive use but it left an impression on me like a giant 25' shark swimming up from dark depths!Doug, I think the steel in the barrel is much harder than the soft iron alloy cases. Look at AKs that have a life of 20 or 30 thousand rounds using soft iron alloy cases.
