Got the bug for a new barrel. Notice there was a group buy from a vendor for 16.5" barrels last year, curious how they shoot. A few things to consider...can .221fb brass be used; can light to heavy bullets be used with the 8 twist or does it need to be a 9 or 10 twist for that. I plan to screw the barrel onto a striker pistol action.

Have a friend with a 30 cal m1 style pistol, (factory gun from where I can't tell), stock is crappy but it's a hoot to shoot. The cartridges look similar to the blk or the whisper.
