[QUOTE="Desert Fox, post: 123011, member: 396"] I read about this in an article written by Rick Jamison of Shooting Times magazine.He did some testing to find out if the listed maximum load on several reloading books were really maximum. His result were conclusive. Majority of the listed load were endeed maximum. Few even went beyond maximum SAAMI spec. He used 30-06 rifle and the Oehler 43PBL for his test. We all know that no two rifle are the same. Maximum pressure on my rifle doesn't necessarily mean maximum on yours. My 280 Remington load of 56 grain of IMR 4831 to propell the 150 grain Nosler Ballistic Tip close to 3000 fps is beyond maximum on any reloading book except the old IMR reloading pamphlet.No sign of high pressure at all. Most of the brass that I used on this rifle were reloaded more than a dozen times. The load for my 300 Win Mag Model 70 Laredo using 180 grain Hornady BTSP according to Hornady 4th Edition Reloading Manual should never exceed 76.7 grain of H1000 but according to Hodgdon it should be 83 grain. Well I found the middle ground, I used 81 grain and even that it's probably redline. But who cares, the rifle groups half inch or better. The bottom line is, you could probably push the envelop a bit with careful handloading but is it worth it.
