7mmTCU. I got it for shooting IHMSA, then bored of the game, but still have the barrel, dies, and stuff. Very accurate, shoots flat, would make a good hunting caliber. It's one of those small for the bore case volume jobs that is very efficient with faster powders and inherently accurate. The TCUs were designed for the IHMSA game. The 7 with a 150 match king bullet carries a lot of momentum on those 200 yard rams.
