250 gr a-tips and Ramshot Magnum in 300 PRC?

[Jayhawkhuntclub]

I see Ramshot Magnum is right between H1000 and Retumbo. Anybody use it for 250 gr a-tips in 300 prc?
Would the data for H1000 and Retumbo be usable with Magnum (starting near minimum loads)?

I have a bunch of LRT (one step slower than magnum) that I was going to try with 250 atips. But who knows if I'll see my action this year lol CdG LA

I tried LRT with the 250 A-Tips. 84.5 grs gave 2866 fps, but with an SD of 29. I need to get back and work some more with this powder and see if I can get the SD down.
