[QUOTE="Gunpoor, post: 894247, member: 8358"] When a stiff bolt lift and shiny areas on the case heads are present together on a spent case beware you are treading on dangerous ground, metaphorically speaking. Some rifles/chambers are different when pushed to excessive pressure, for instance another rifle may flatten primers and swell primer pockets so the cases are unusable for another loading but will never exhibit sticky bolt lift. I once had a Winchester rifle chambered in 7STW that when loaded with factory ammo (two different boxes) , after three shots the bolt would hardly open almost to the point of breaking off the bolt handle. This rifle showed no other evidence of excessive pressure what so ever. I sometimes read accounts where handloaders will start load development at the max charge of powder according the their data manual and it makes me cringe because I have had a rifle that if loaded to this level would probably have experienced a KABOOM. I have also read on-line postings by handloaders piously claiming they always adhere to this manual or that one, therefore they never have to worry about their ammo. I have loaded rifles beyond the book and consider data manuals a mostly reliable guideline only. [/QUOTE]
