[QUOTE="MagnumManiac, post: 990325, member: 10755"] The one thing you will NOT see is hard bolt lift until pressure is well beyond excessive. I have a few AI's, the most significant excessive pressure sign is ejector marks. Primer appearance may or may not indicate excessive pressure, but several other signs should tell you to back off, such as ANY case wiping, sticky extraction (which is different to stiff bolt lift) . Accuracy? In my experience, the fireforming load will be more accurate than when you fire the fireformed cases, I no longer shoot bullets when fireforming, I load shotgun powder and fireform with a twist of tissue, or for my 375 Weatherby, a plug of soap. I work up with the fireformed cases testing for groups, there will be a load combo that works, but I've always found that COAL and the sweet spot has made more difference than other factors. Hope this helps. Cheers. gun) [/QUOTE]
