gonna add a vote to the first response and say 240. Just got mine for the exact use you had inquired about and I love it. I have a MK V Super Varmint Master in the 22-250 and it has done well for me, but it is just too heavy and bulky for me. I knew i wanted a new varmint rifle I wanted a MK V Ultra Light Weight. If they had had it in a 22-250 or 204 i most likely would have gone with one of them, but now that I have seen, held, and shot the 240, I am happy they didnt. This thing is a tack driver, fun to shoot and easy to carry. Plus it will be the wife's weapon for any of her big game outings. Out of all my firearms, it is fefinately in the running for my favorite!
