Broke another bolt.... your thoughts??

[Cajuntransplant]

Silencers don't increase chamber pressure significantly. You're not breaking lugs because of dwell time or port pressure (adjustable gas block). I'd wager you have/had a short throat. Measure the throat on the new barrel and load accordingly.

You think the chamber/throat was incorrect and that’s what was causing me to break bolt heads? Could you explain why or how that would cause the bolt head to break? I don’t follow.
