I tested my 6mm AI tonight with H4350 here in Indiana with 44 gr. and a 105 Berger I was at 3173 on the magneto speed. This is about as hard as I'm going to run my gun. Once the 6mm AI lets loose I'm gonna go 6mm Creedmoor no more fire forming !
I sure do love mine ! We're in the process of building my buddy a 6 mm Creedmore so I'm pretty anxious to play with it also I know velocities are not going to be as high but I do like the case and that we don't have to fire form
