Curious if either of you actually tried increasing the round OAL to see if that cured the problem or just popped for a new spring?
I don't shoot an Axis so maybe there's a difference between the 10,110,12,112 etc. or the Axis?
And thinking back, the few FTF that I experienced happened on my XP 100 converted rifle in .221 Fireball. Case OAL cured that issue and it has never happened again.
