[QUOTE="Greyfox, post: 1108643, member: 10291"] I have now been through load development with a couple of 300WM rifles where my ES with H1000(74-76gr) was running 35-50FPS. A switch to Retumbo(77-79gr)would give the same accuracy, .25-.5MOA, but an extra 75-100 FPS and ES under 12FPS. Using Norma brass, Fed215's, 210 AMax, 210/215 Bergers. I have generally found that a powder change has the most profound effect on ES. I'm getting 2900FPS out of my 24" Rem Milspec with 79gr Retumbo, ES 8. [/QUOTE]
