I was using federal 115gr fmj. Federal 95gr fmj, and Mag Tech. 100 rounds total. Jams were more consistant when loading over 10 rounds. I may have to try your suggestions Nealio. I talked with Henning, he and EAA are plum out of rear spacer mags. I sent the gun to EAA, hopefully they can fix the problem in a somewhat timely manner. If they cant, I will try your suggestions, and maybe Mec Gar and Pro Mag magazines. I appreciate everyones input on this.
One of the things can can happen is you can get undue drag on the front of the follower from the spacer. Remove any burs and loosen the channel in the follower where that front spacer goes. That helped my front spacer mag feed better.
