in a Winchester white box case, pull the bullet, so you don't have to bother setting up to size,use the existing primer. do this 5x, run them across the chrono, 11.5" barrrel. 2600 fps is GUARANTEED, 2700 fps possible, depending upon the barrel.

It will be pushed deeper into the cartridge setting up very high pressures.andy said:in a Winchester white box case, pull the bullet, so you don't have to bother setting up to size,use the existing primer. do this 5x, run them across the chrono, 11.5" barrrel. 2600 fps is GUARANTEED, 2700 fps possible, depending upon the barrel.
