Does anyone have any good loads for a 256 Win. mag.? I will be shooting a 21" contender barrel. With 60 to 80 gr. bullets. Thanks!

i've used 4227 with 60 gr bullets for long time now. never could get the heavier bullets to work as well as the 60's. best one is long gone but was a speer 60 gr spitzer. now all you can find are blunt noses.
