Thread: 22-250

If you are getting a new barrel go for the 22-250AI chamber your brass will last longer and you can up the velocity if you wish, I had mine done with a 1:10" twist it would put Hornady 60 grain HP
all through the same hole at 100 metres and turn 52 grain match bullets in to smoke with max loads,
I really only had it done to get a longer brass life it did that very well the 40 degree shoulder stops the brass stretching only neck sized the cases had a body die to bump the shoulder back
every 5 reloads could reach 22-250 velocities with lower pressure and still have a 100 fps more on tap if needed.
