shank size for 7mm RM

[Sponxx]

Hey guys, I got a 110E in 7mm RM with blind magazine that I bought used. So far I have bedded it and installed a Timney trigger, this gun shoots about 1MOA consistently with my handloads, sometimes even less (on work up phase) and shoots about 0.7 with Fed premium ammunition and 160gr partitions.

I've thought about getting a new barrel when I finally wear this one off, (no idea how many rounds since I got it used) and a heavy recoil lug.
I have a few questions for down the line.

Do you know what the shank would be? Standard vs large?
Thanks!
