[QUOTE="Guest, post: 68123"] I have gone as high as 86rs of Retumbo with the 240 SMK in my 29" 1-10" twist Lilja barreled 300 RUM, accuracy was best at 82grs. I haven't chronoed it yet and didn't get any real high pressure signs, bolt lift wasn't hard at all and the primers looked good but was starting to get ejector marks in the brass at 84grs. My other RUM does the same thing and I think it's the Rem brass. The primer pockets get loose real fast when I see those ejector marks and I'm not shaving any brass, just seing marks. Wayne [/QUOTE]
