The season before last I did take a buck with the 100 grain version of the Ultimate Steel. I think the cut was like 7/8 of an inch or something along those lines. 30 yard broadside shot on a nice buck. I got a complete pass through but there wasn't any blood trail to follow. The buck went about 120 yards or so and expired. I can't blame the poor blood trail entirely on the head because I did hit a little high. But the wound channel was very small.

Long story short, I just feel there are better heads out there to use than these.
