Thanks ZZT.
I just looked at the bag I got from Cajun, it is the 13# spring. It doesn't make sense to me to make them longer but I know that I have heard that before. The lips are all good to go, tuned them after the last time I shot. I just installed Grams followers and springs cause the CZ custom follower and springs wore out. I couldn't get the CZ custom followers to stay straight and the springs were very loose where it attached to the follower. I have never had an issue with any .400 bullets, so it sounds like that might be the issue. It seems like when the bullet hits the feed ramp it sticks cause of the coating, slowing it down. Then it gets about half way in the chamber. I think I will be going back to Montana Gold and just use the acme for practice only.
