I was in a LGS yesterday and seen that they have R-7 in 5 lbs. for a reasonable price. I have only used R-7 in 300 BO sub loads with cast bullets, with a degree of success. In 8x57, I have used IMR-4198 with gas-checked cast. Plus I have been giving some thought on getting a single shot rifle in 45-70, which also would be with cast. Also I may start casting for 223, though I have much jacketed bullets on hand.
I'm be curious to hear of anyone else's experience using R-7 with cast. Good or bad.
I should mention that I plan on eventually get into using Hi-Tek powdered coating. But for now I'm just using Alox.
