My dad is looking to start reloading for the 10mm. We have a small collection of once fired case from the 500 rounds or so of Double Tap I have went through. They haven't buldged noticeably and I have no doubt the cases are safe but to prolong case life, I want to get a KKM barrel. I know it may not be necessary, but I figure it more than likely won't hurt. I just want the standard length and would rather not have to have it fitted--don't know if that is an option with the KKMs, just checking. Want to know where the best place to get the barrel would be. My credit card it kinda stressed right now so they must be able to take check or money order. Thanks.
