I blew thru both shoulders of a WT Buck at 100 yds, about a 150 lb 8pt, young buck, 20" 243 M7 XCR

Killed a few more via a 6mm BR Dakota - lung shots, nice exit holes under the hide, plenty damage.

My overall go to bullet in 6mm, it expands well and retains energy downrange, as well as retains weight and penetrates, near and far. Hard to beat all around, and I would not hesitate to 500 yds or so if I had the dope to punch vitals. Oh, did I say accurate? 1/2" was the norm at 200 yds in the BR.
