Anyone out there who has tried Norma MRP
powder in the 300RUM.

Taylor

ive always heard that rl22 and norma mrp was the same powder.if so i use 96 gr rl22 and the 150 sierra for 3611 fps and 1.75 inch groups at 300.92 gr rl22 and the 165 sierra gets 3400 and about the same groups.

Hello Erik

Thanks for your reply,i dont think reloader22
and norma MRP ar the same.Spoke to Norma the
other day if MRP-2 and reloader 25 are the same and they told me no,but they dont have any loads for the 300RUM with MRP.Have you
tryed to load with hevier bullets 180-200 gr?
