I have the RCBS mold for 35 rem boolits, 35 cal gas checks, some tin, some pure, and a pile of COWW ingots. My eventual goal is to have a suitable deer load (probably mulies) and hog load developed by next Fall. As a stepping stone to that goal, I also want to cast up some boolits for target loads from the same rifle. Based on a lot of reading here, I will be aiming for 50/50 plus 2 to 4% tin for the hunting rounds. Is there an obvious problem with casting straight COWW target bullets, working up a load and then using that load for the hunting rounds with the 50/50 + tin alloy? Any reason to expect markedly different accuracy, POI, etc. with just an alloy switch? The reason I ask is that if I have to go two separate tracks to develop what will be completely different loads I would rather know up front and plan accordingly.
