Finally bit the bullet and had a Mashburn Super body/shoulder reamer made so I could use different pilots for different calibers. Haven't picked up the 6.5 barrel yet but do have a nice 25" 270 barrel waiting to be chambered. My first one though is a 8mm with a 26" barrel I should have ready to stock in another few days. I just wish someone was making good high BC 8mm bullets but I think a 200 gr Accubond at 3200 fps will get an old bulls attention.
