I've shot thunderhead broadheads and think they're great. I purchased some thunderhead xp broadheads because they were half-price at a archery shop that was going out of business.
I've been practicing with field points and thunderhead broadheads on my 3 D target.
I figured with bow season just about a week away I should put together those new thunderhead xp broadheads and shoot them to make sure they're going to fly like the thunderheads do.
Well, I actually think they fly a little better, but they really excel on penetration. The XP went completely through my 3 D target by about 2 inches.
All I can say is Wow, what penetration.
