been shooting a M&P 9mm for a few years now and decided to try out a kkm barrel. All my reloads for my factory m&p barrel run great, but when I switch to the kkm. I am getting lite primer strikes.. one right after the other. I know my primer seating is fine...been using the Dillon for years now and never had a problem... So is this a COL/OAL problem???

Does it run OK with factory ammo? Might be the chamber is on the tight side and the reloaded cases are dragging on the chamber walls, preventing seating the lip of the case against the chamber fully.sigpic

that's a good question, I will try that tomorrow... I think I have some factory ammo somewhere, I will have to go look for it..1 John 4:15 "Whoever confesses that Jesus is the Son of God, God abides in him, and he in God."Comment

Quick question
Sounds like maybe it was reamed to deep to headspace on the case. Now the chamber lets it slide to far forward. Use you digital calipers and measure it against SAAMI specs. I would call KKM and tell them you want a new barrel. That is no cheap barrel.
Before all this try using a lighter crimp. Maybe for this barrel you are over crimping them and the seat too deep. Either way call KKM.
