Broke another bolt.... your thoughts??

[Randy99CL]

This mean my barrel and bolt aren’t lining up properly? That, combined with my hot loads, ultimately causing failure? Or is the wear from the hot load and bad unlock time?

Yes, the bolt isn't aligned well with the barrel extension. I'd guess the extension is the first thing to check; I'd pull the barrel and take it to a gunsmith who could spin it in a lathe to see if the extension is straight. Even if it is only out by a small amount, guessing maybe less than .010", it could make a huge difference in the lugs seating evenly.

Don't think the hot loads or unlock time could be doing this.
