Re: Loading for a .300 RUM
I shoot a 208 Amax in my RUM. Retumbo may get you more velocity, but with a higher ES than H-1000. My extreme spread is in the single digits using H-100. Im shooting over 3kfps. Right now barely over, but im trying to work up a super accurate load and that velocity is working really well for me, with an extremely low spread.
