SC,

Thanks for detailed response. I don't know about all that spine shooting stuff (new to me). I do know that if you shoot a little high behind the shoulder that the deer seem to drop in their tracks, I think b/c of the massive initial force against the bone. Is that what you are talking about?

Yes, I am sort of a big damage person b/c usually I hit where (or near) I am supposed to. I don't really value ribs that much, and it usually doesn't tear up tenderloin, backstrap, and front shoulders if you hit in the right spot. At an angle (quartering towards me) I have had BT disintegrate and not exit, but cause massive internal damage and drop the deer. I'm gonna stick with them until they fail me (always blame equipment eh?).

Any truth to the fact that recently to address problems the BT has been beefed up? Also, I'm shooting the 150 grains and not the 130s, don't really know why, except I thought that 130 would be even faster and more chance of disintegration. Any thoughts?
