I got all my reloading equipment unpacked and am about ready to start cranking out loads for my model P. I have 60 rounds of once fired Remington Brass and 20 rounds of Hornady gummy tip brass to start with. The only rifle powders I have on hand are 4064, 4350, and 3031, also have a couple of pounds of H 110 and unique. So I'm going shopping this next week for more powder, slugs, and a new set of powder scales. My old scales were damaged in packing apparently and I do not trust them any more. So what powders do you guys recommend I look for and what are your favorite loads with those powders. I will be topping out at 300 grain cast bullets and downwards from there. edit to correct typos
