[QUOTE="Long Time Long Ranger, post: 507679, member: 505"] I have never looked at a Barnes loading manual but would be concerned about shooting loads that light. 87.5 grains of H-1000 is around 15 grains below max in the rifles I have shot. 84.5 grains of Retumbo is around 20 grains below max if you could get enough in the case. Just flat out can't get enough of these in the case to get a max load. My best load in the rifle I shoot now is 99 grains of RE-25 and that will shoot extremely accurate in the high 3200's fps. That is the slowest extruded powder you can get enough in the case with. 94.5 imr-7828, 98 grains magpro, 96.5 grains winchester WMR all shot very good groups from mid 3200's to 3300 fps. These are with Fed 215 primers. I guided my brother last year on a mule deer hunt and he got a nice buck at 680 yards with 99.5 grains of RE-25 and the 225 ttsx out of his 338-300 RUM at 3280 fps. Most accuracy loads are interchangeable between the 338 RUM and 338-300 RUM. They are virtually identical chamberings performance wise. Max will run 2-3 grains higher in the 338-300. I agree with the guys saying go faster like between RE-22 and Re-25. Look at a burn rate chart and get a powder in that range. These will fill the case about right with a max load. If you have RE-25 start around 95 grains and work up. With RE-22 start at 91 grains and work up if you have that. Look at a burn rate chart if you have powders between those you can extrapolate pretty close. [/QUOTE]
