RR, it's time for you to come charging in and remind everyone of your discussion concerning this and Gutted's chart showing exact lead angles for a 90° hit and how just using generic 10°-20° lead angles results in a hit a little before or after 90°. Unless I'm missing something and there is a minimum degree over or under 90° that you need to attain to prevent the 90° firing pin issue. There are alternative methods of attack that preclude this possibility also since this problem seems to associated with an O'kane attack. I have never (as far as I know) had this issue. Duds and fish that run under their targets are common for me but not firing pin issues.
