What cartridge are you using? It looks like a short action?
Anyways...I have a 270Wby with a stock chamber, 1-9 Benchmark barrel. Freebore is .376". I can load to any COAL that I want. No accuracy issues...get as much freebore that you can stand, so you are not limited to one bullet. Look at the limiting issue of the longest COAL of your magazine. Then go from there...
It will be a .270 wsm on a model 700 short action.
