Himmel, I had a 7mm BR rifle 21", shot 120's at 2878 and recoil was mild, but a TCU would be 'soft' as I had a 14" TC and it was sweet! BR cases last forever, and TCU likely do better in bolts as the TC lends itself to some stretch, due to action, etc.

TCU good to 200-250 on deer, BR-how well can you shoot! BR for me would have been good to 300 or further if you can place a shot with a bullet that will expand well, a 120 b tip would be likely ideal, but a 130 at 2670 was not bad either.
