I have a Tc contender chambered for the 7mm tcu, it has a 14 inch barrel, I used to shoot metallic silhouette with it in the 1980's. My favorite load was 25.5 gr of Win 748 with the 140 sierra, I put a scope on it and now use it for a short range plinker or varmit rig, 100 gr sierra hollow point and 31 gr of WW 748 produces 1 inch 100 yard groups.
