Make sure you check through your orings internally, front can, back cap and rear can, bolt sail, bolt guide, what bolt is in it?
Information would help your case tremendously.

I think it's an oring issue. Try relubing your bolt and see if that helps.

Change the oring inside of the back cap. Raise the dwell to 18 and the fsdo timer to 16 and see if it shoots then.

Do you have buna o-rings? If so, try installing urethane. Buna increases the friction and can swell. Also, you should only use DOW 33 grease. Every other grease that we have tested will cause the o-rings to swell. If installing the proper o-rings and using the correct grease does not help, try raising the first shot drop setting to 15ms and lowering the FSDO timer.
