Broke another bolt.... your thoughts??

Sounds like you are just too hot. You don't need to see pressure sign to be way above design spec. Like magnitude 10 -15,000 psi higher before it shows on SRP, higher w/match or mag primers).

Breaking an extractor, imo, can be DI related. But breaking lugs (most especially if it is one adjacent - imho) is too hot. Loading too long, short leede, tight bore, monolithic bullets like GMX. Cans, as discussed, can dirty a gun - not really via the tiny diameter gas tube but through the larger bore. They act like a longer barrels, and a longer barrel simply holds pressure longer, they don't really elevate chamber pressure.

Drop your charge a bit, then a bit more.
