Re: Reduced 300 RUM loads?
I load a lot of reduced loads for bigger rifles, mostly 300wm, and 7mm Rem mag.
The best powder for these is sr4759, but for anything bigger than .308, or the biggest .308s xmp5744 is your best bet. Ive shot the 220 smk’s over as much as 43 grains of the stuff. Book data ive seen is 30-38gr.
Of course, if youre thinking about lighter bullets, send me a pm. The 220SMK is the bullet I shoot most, and id be willing to trade if ive got something you want. Ive got .308 cal bullets as light as 90 grains. Ive got reduced data for them as well.
