While some swear by the "use all the energy inside" no-pass through school, I, personally, subscribe to the two-hole-are-better-than-one approach. I like bullets that go through, liquifying the organs as it goes, making a big hole going out the other side. I've always gotten better blood trails with a pass thru than with no exit, and the deer go down just as fast if you shoot them in the same place. I'm going to try Barnes bullets this year in my ML. I've heard excellent things about their bullets. They open fast and still penetrate deep. I was hesitant to try them because I believed like many others that any bullet that can penetrate like the Barnes TSX/TMZ bullets must open slow. This is not true. Barnes has high-speed camera videos of TSX bullets hitting 10% ballistic gel that open completely in the first inch of penetration, but still outpenetrate most other bullets, while creating an impressive wound channel. I think that this has to do with the all-copper construction and the sharp edges created when it opens compared to the dull mushroom of lead cored bullets. So I'm very curious to see first hand how they perform on game. Although all the on-game reports I've heard on Barnes copper bullets seem to be very positive.
