Has anyone in the forum had the 5th rd pop out when ejecting the 4th rds mty brass on their 03? Happened to me a couple of times yesterday when test firing my 1903 ‘school’ rifle build. I swapped the milled follower for another that I had and put a shim under the mag spring to eliminate the wiggle where it slides in the baseplate. With mty brass it seems to work ok but I’ll shoot it this week for real. What causes this? A weak spring or the follower?
