Sounds like your gun is cranky with ammo. Are you shooting soft points? Are the noses hanging up because of exposed lead? M1 and M1A are supposed to be very picky on the correct powders to work. Have you chronographed the loads. Tried different magazines? Around 2600 to 2750 fps with 150 grain bullets is about right. I would think most commercial ammo is using powder that will work in M1s but who knows. What load are you having problems with?
