JAB Posted February 25, 2013 Share Posted February 25, 2013 So how do you guys tell if your barrel is shot out the gun is a 9MM. Is all started after i changed my front sight and started shooting some reloads that person gave me.The reloads look like they have a tight crimp on them and some the rounds are key holing plus my grouping is all over the place they are lead not jacked.

Powder Finger Posted February 25, 2013 Share Posted February 25, 2013 Don't base it on someone elses ammo. Use your own or factory of known accuracy. Quote Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted February 25, 2013 Share Posted February 25, 2013 Don't base it on someone elses ammo. Use your own or factory of known accuracy. +1. Sounds like the lead bullets might be crimped too much. Quote Link to comment Share on other sites More sharing options...
