I was having the same problem, until I read this thread. Thanks a bunch guys. I always had to wear an arm guard, however after reading this thread a couple weeks ago I changed my form and now shoot bare armed with no contact. I really appreciate everyones advice and opinions on this site.

Bowhuntt's picture above was a huge help. I had my wrist too far into the grip or in other words the grip rested in the middle of my palm. After seeing the illistration I corrected the grip problem and no longer have the problem. My groups have tightened up as well. I hit 4 out of 5 bulls 3" from 50 yards. I did this on three straight rounds.

Thanks again.
