I've had mixed results with them. I'm looking for consistencey therfore I'm sticking with Muzzy's.

A buddy of mine shot and 8 point last night at 20 yards @ 65# 30" axis arrows and 100 grain3 blade Muzzy. He hit the leg bone and broke it into pieces the put a perfect star in the heart still this arrow had enough energy to fall out the opposite side as the deer ran away.

If he was shooting Spitfires I don't think he wouldn't gotten any penetration.

Muzzy BAD TO THE BONE
