Searching for some wisdom regarding cutting down a 26" 1-12 twist Remington varmint 308 barrel. This rifle is being repurposed for deer hunting in the south east. Max I'll need to shoot this will be 600 yards on game. I currently load hornady 165sst. I bought some of the 178 hornadys to load this year and I'm concerned that cutting the 1-12 barrel down to 18-20" won't leave enough barrel to stabilize the heavier projectiles. What's the consensus on 18-20" 1-12 twist 308 barrels? Should I just chop it to 18" and shoot lighter hunting projectiles?
thanks
