Thanks for that info about the ABS barrels, Buffalo............
KIRBY, I like the idea of the .375 AX, and McMillian WILL inlet the A5 for the CZ550 Safari action---I've already asked. ;^)
I have also had "reservations", shall we say about the sharp shoulder on the .338 AX, however with the length of the bullet, it should help it feed properly. Nice to know that I can just go with a heavily fluted HV profile barrel in the 27-30" range. Still waiting for the .375 Sierra Matchking to show its head, and to compare ballistics to the 300 grain, .338 caliber Sierra Matchking with equal "boiler rooms."
Kirby, as you know, I love Bigbores, and actually shoot my CZ550 in .416 Rigby PRONE off of a Harris Bipod (I'm NOT kidding y'all!). Without any muzzle brake, it makes for some dramatic shooting I can assure you!!! LMAO!!!
Here it is in its current .416 Rigby form (27" barrel) with its factory sights and rear sight block meticulously removed, sandblasted, and reblued ALL by ME (of course I intend to add a Nightforce 5.5-22x56 R2 or R1 as the project comes to its finale---YES, I know, I need HIGHER rings.), and I also intend to add a Badger bolt handle:
One more question KIRBY......Do you think that you could "adapt" a .338 Lapua Wilson Hand die (neck and seating) with your reamer??? I like the ability to load at the range, and I tend to neck size only after the initial fireforming.
