After the results on my black bear this spring I will definately be changing my broadheads. I used steel force on my bear. The first shot (due to angle) went in behind the shoulder and up into the spine....this one literally disintegrated, I pulled it out of the backbone in about 10 peices. Once the bear was down I finished him with a shot from 10 yds this one broke a rib going in but did not even puncture the opposite side at all. The top 1/2" of this one was curled right back on itself. I shoot a 420 grn arrow at 290 ft/sec....from 10 yds pass through should not have been a problem....was not impressed with these heads at all and will never shoot them again. I have some Magnus stingers i am going to try, also some Montecs that a buddy has had great results with.

You can clearly see the lack of penetration in the pic below
