RE: Pressure Signs
Mainehunt.....all these indicators are simply that.....INDICATORS!!!
IMO the best indicator is to use a micrometer on the case immediately ahead of the extractor groove. Further if you are only seeing flattened primers and none of the other symptoms I'd venture a guess that you're all right. These are the signs folks have used for years short of pressure barrel equipment.
Further these signs don't necessarily mean the ammo is too hot...it could mean a flaw in the barrel or too long cases... Experience helps!!!
