Barrel blank for AXMC, shank diameter?

[Kiba]

Just got notice that my AXMC is shipping, so I want to get a heavy palma gain twist blank on order from bartlein for 300 PRC. I know the AXMC uses larger tenon threads than the short action AI, but are the barrel blanks for the AXMC the same 1.250" shank diameter or are they larger? I want to make sure I give the correct info to bartlein even though they probably already know what I need.

Thanks!

Call Dave Tooley. He has some "in stock" Bartlein .30 heavy Palma 28" 9 twist blanks last time I talked to him. He was going to spin up one in 300 PRC for me for my AXMC, but I have too many other irons in the fire at the moment.

You’ll need a 1.350 shank diameter.

Want to do a gain twist, so I'll be ordering a custom blank. Currently running gain twists on my 6.5 creedmoor, 6 dasher, and 223AI and really liking them, want to do the same with the 300 PRC.

You’ll need a 1.350 shank diameter.

Perfect, thanks! Off to call bartlein.

Just an FYI to help anyone else with the same question... just went and DROS'd my AXMC today and the barrel shank measures 1.338", slightly smaller than the 1.350" stated above. That also matches the print posted on Proof's webpage here:
