X2 on the 6.5 Sherman
Or have your bolt face opened up to a magnum cartridge. Then you could shoot the 7 LRM, 7 rem mag, or the 7 STW. Or if you are able, sell your existing bolt and put that money towards a PTG bolt. That's what I'm doing on my build. It gives me a precision machined bolt in whatever size I want and fluting and oversize bolt knob are done already. It is a few more dollars , but if you were planning on fluting/bolt knob/blueprinting, it works out. Not to mention the one piece bolt body/handle that PTG offers.
