You are missing the point.....go to
www.rocketaerohead.com and read the "Science" behind why they bend.....
They are designed that way on purpose, they will deflect and BEND around bone taking the path of least resistance thru an animal.
I also have a ton of first hand experience with these heads....it's been my "Go-To" since 1997.
I can tell you this.....I've taken about 12 deer with that exact head, and it is not junk.
I had one shot at a large bedded doe on a hard downhill shot.....Her back was to me and I put one right thru her spine,the edge of her heart a lung AND shattered her leg bone tucked under her......2 blades were badly bent but not broken and the entrance and exit wounds were huge. This is also the ONLY deer that my arrow did not pass thru.
In fact every deer I've shot with these has had huge holes and not one.....and I mean not one has gone more than 75 yards on a dead run.
They really aren't designed for target practice.....figure out if they hit with your field points by messing up one, and put em' away. They're meant to be shot at game.
Mine fly EXACTLY like my field points so practice with them is silly.....don't give up on them because the first animal you shoot will change your mind!
Also....with it's 1 3/4" cutting diameter you'll be best served with about 65# or more of KE for deer sized game.
And although a decent Turkey head you may want to look at the Hammerheads for the serious "Whoop Factor".
