I have been trying to do the same thing. I have a Weatherby Accumark in 300 Weatherby mag and have been using some SMK's in 200 grains. Could not get any groups at lower loadings to shoot very well. My WBY likes 'em a little on the hot side. Been pushing 3100 fps with the 200 grain MK's with 86 grains of Reloader 25. A little faster with 87 grains and bolt sticking with 88 grains. Groups have been under 1", but would try to get them smaller. At 87 grains the first 2 shots overlapped half way. The third shot moved it out to 1". Hate to say it, but I think it was me, so I stopped there for the day. Hope to get someone else to shoot it and see how they do. Would be very interested in How your load developments have been going, Boyd. Hope you list them here, or maybe e-mail me with your results. littletoes.
Hope we get some new results posted!
