Verify you're not causing problems due to excessive flare, improper sizing, or insufficient/excessive crimp before you move to changing the OAL.
Would excessive flare or improper sizing cause the case to stick in the chamber instead of slide freely?
Do you guys trim 9mm cases. From what i've read it sounds rare to do it unless you are doing some competition shooting. It sounds like from load to load they pretty much stay within appropriate length.
Thanks for all the feedback I appreciate it.
