No, I ran into this one time. I recall making a new pin for some odd reason and believe it was for the difference in the bolt bodies. Early bodies were the same diameter their entire length whereas the newer ones are undercut in the cocking ramp area. One or the other used a longer / shorter pin. The bodies in my 10s are straight. The rest (11,111s, 200s, 14s,etc) all have the undercut bodies.

In the meantime Mossy take a few measurements. I have a pin here but no idea which one.

Overall length - .657"
Head diameter - .427"
Shaft, tip to the bottom of the head - .478"
Shaft diameter - .211"
