Hey everybody, I just made an observation. I've been loading 200 gr. hardcasts with 10 grain blue dot. Ok- I seat the bullets to 1.26 OAL-, then after I run them through the lee factory crimp die (one full turn for a tight crimp), the OAL grows to 1.27. I've been shooting this load for a long time now and don't have any problems with it, its a nice full power load, no pressure signs etc. I'm just wondering why in the heck it grows, and is a max oal of 1.27 going to harm my glock 20, I have a 6 inch wolf barrel by the way? Wanna kill these ads? We can help!
