[QUOTE="LR65Pb, post: 1625564, member: 89313"] I agree with the H1000 posts. I'm shooting an AR30A1 from Armalite and for some reason both it and my AR30A1338 Lapua like hotter loads. On the 300WM I load 78.4 gr of H1000, 215 Magnum Match primers and seated .001 off the lands. I spent a great deal of time testing Retumbo (whi h I use in the 338Lapua) but I couldn't duplicate the H1000 results. That combination has yielded multiple sub .2 moa groups at 100 yds. At 1000 yds on a 12 inch ar500 target it easily groups sub moa with 208 Amax (i know), 210 noslers and 212 eld's. My load is my load, but finding my oal on the lands and working from there helps me better when workin up loads on a new rifle. Watch for pressure signs and work up in tight grain increments when you're close. I chased "velocities" of others but it took longer to find my own accuracy nodes. For me, accuracy is number 1. My velocity is 2850 fps on a 24" barrel. Good luck. [/QUOTE]
