Recently inherited a nice M1917 with an almost new Criterion barrel in .308. Mag well has a nice fitting Delrin spacer and first round inserts into mag fine. Adding each of the next 3 rounds cause the follower to pivot up and down and pivoting up when bolt is pulled back. Follower was trimmed just behind and in front of mag spring. Before I try soldering tabs on each end of the follower, has anyone else solved this problem? Thanks for any advise.
