Thread: Will Shortening my barrel cause issues?

Hi all, I have a Zastava Mini Mauser in 7.62x39, I load my own Subsonic rounds and would like to get a suppressor to suit, an overbarrel suppressor adds 100mm roughly in total length so i was thinking about having it cut down 100mm at the same time as getting a suppressor fitted, but im worried with doing so the accuracy will be effected, my loaded sub rounds run lead 151gr projectiles, im not sure if having a much slower projectile in a cut down barrel will suit the twist rate of my barrel or not, has anyone had experience in doing this. Cheers
