[QUOTE="crkckr, post: 2756900, member: 78056"] Using primers to "read" pressure can be done but you have to know the firearm & primer brand well to do so. Without some experience it's little more than a crap shoot. It is best done in conjunction with a chrono! As has been stated before, but cannot be overemphasized, if you are experiencing any abnormal bolt lift, you have far exceeded max pressure! I'm not sure backing off just one grain is enough! If you're going to work in that max pressure realm a chronograph is a necessity. They don't cost that much and although often a total pain in the rear end, are worth their weight in gold when they work right! Playing around in the max load world can be dangerous to your firearms and your safety. Don't do it without all the tools you can afford! Using the case as a pressure measuring tool can be as much of a crap shoot as using primers! So much depends on the case itself that even small changes can make a big difference, especially brand changes. Any measurements taken must be consistent as to placement. Records must be kept! I suppose the absolute best way to do it is to use the p'electric sensors. Personally, I simply can't afford the equipment, not to mention I'd probably scare the snot out myself measuring some of my loads! Until I win the lotto, I'll have to stick with my chrono & my personal brand of voodoo! Cheers, crkckr [/QUOTE]
