I wouldn't consider myself a loyal steel force user but I would give them a thumbs up if you want my opinion. I would agree they may not be the strongest head on the market but in some testing that I did I didn't experience any "peening" until the third shot through a steel drum. They flew fine as long as my fletchings weren't beat up.

I haven't taken a lot of game with them but the two bucks that I did harvest (one a quartering away shot where the arrow went the length of the body) were complete pass throughs and both heads looked like they just came out of the pack (still sharp, in fact sharper than some heads I have seen before use).

I know of a number of guys that use them on elk and they have nothing but good to say about them. One in particular took a bull last year shooting a Q2 at 55 lbs. and got a pass through with the steel force. Another guy I know using a recurve got a complete pass through on a buffalo which I thought was impressive.

Good luck.
