[QUOTE="MagnumManiac, post: 261568, member: 10755"] Tom, I am getting 3188fps with Nosler 180gr Accubonds, and 3177fps with Woodleigh 180gr PP's. Only 2 bullets used in this rifle of that weight. I have loaded well past Alliant's recommended maximums, with complete safety, and my loads are 180gr bullets RE25/81gr's, and 200gr bullets RE25/79gr's, neither load is maximum in my rifle, in fact I worked up another 3 grains with both loads, and case heads were just starting to expand. MY chamber is 'match grade', I do not need to turn necks, I have .001" play with the brass I use. I don't see how the WSM would get 2900fps, even with max loads, because the bullet takes up too much of the powder space, if Alliant are saying 2857fps in a 300WM, surely the WSM would be slower, even in the same length barrel. When we compare velocity from a machine rest pressure barrel to a hunting/target rifle barrel, there are considerations that must be taken into account, most test barrels have far tighter tolerances than even a match grade barrel, which will generally give higher pressures and velocities than a match barrel or hunting barrel, and do we know if the publisher is 'fudging' their velocity readings. All of my loads have been chron'd on my chrono and 2 other chrono's to be sure that there isn't a misnomer at play. Cheers. MagnumManiac. gun) [/QUOTE]
