Back in the day I was using the Hornady 110 grain hollowpoint. I just looked at my old notes, also using IMR4350, the groups got tighter the closer to max I got. Those bullets are getting harder to find but the V-max has a better coefficient anyway.
Over the years I've gone to smaller calibers for varmints. It was fun to watch the spray, but whenever a farmer asks what I'm using I feel a little more comfortable telling him it's the small stuff. It's getting more and more built up around here. If you have lots of wide open space a 270 can be a great varmint rifle. My old 270 still holds my record for the longest groundhog kill, 450 yards. (stepped off by two people)
With all that said, if I were you (based on what you wrote) I'd just sell it and get what you want.
