GG I am pretty sure Gene Simillion has a reamer.
Also PM Dave7mm on here. I think his smith has a reamer but don't know the smith myself.
What's the real difference between the 7 Mashburn and a 300 WM necked down to 284 ( 284 Jarrett ) besides a slightly longer neck on the Mashburn. Does the Mashburn have more powder capacity too ?
