So how do you guys come up with a best OAL for you gun. I know it changes from one bullet type to another but lets just say you can chamber a 9mm 124 fmj with a OAL of 1.175 and it runs good in the mag. But the load data has 1.090 can you go that high or is it just too dangerous. Also isnt the best accuracy at when the bullet is just off of the riffling in the barrel. Im just saying holy crap there is a lot of contradicting info out there. Wanna kill these ads? We can help!
