I shot a doe earlier this year with the 100gr Rocket Ultimate Steel. I had a double lung pass through, but the blood trail was horrible and it took me 15 minutes to track her 60yds, where she was expired.

Last year I, like you, shot 2 blade magnus heads, 4 pass throughs, but the blood trails were scant.

The next deer I shoot will be getting a 3 blade muzzy.
