FWIW, never had great luck in a few 7RMs using 140s, but the 150BT would do 1/2" for 3 in the last I had, a BDL SS Sporter.......
I like heavy bullets, but that rifle shot that so well, no reason to use anything else on alot of game to sane ranges.......
That said, I am partial to ABs over BTs.......and perhaps PTs for many applications
