Would you use a 270cal 130 grn BTSP speer for black bear? I'm having a little trouble with my daughters rifle. I wanted to use some barnes 140 TSX but the rifle really doesn't like them. I reloaded the 130 grn speers and I've found a couple of different loads that it likes and shooting sub MOA groups. I tried some factory 150 grn winchesters but it's a 2" group Any thoughts would be appreciated.
