I have shot numerous game animals with the BT with very destructive performance. I will not use them on anything I am goiny to eat. Too much collateral damage and copper shards. In my 243 I had dissapointing results and went back to the standard 100gr remington. I find them hard to beat in...
46 grains of Varget or RL15 behind the 168SMK will do the trick.
My LTR also shoots same point of aim at 100 with the same load using Barnes 165 TSX. I hunt with the Barnes and blast with the SMK due to cost.
DOnt spend your time with any other powders as these two are the tried and true 308...
