I'm getting a .243 for predator hunting, and I'm having a hard time finding FMJ bullets. I want something that will produce minimal pelt damage, and I noticed a lot of bullet makers offer RN cast bullets for rifles. Are they good for high velocity rifles like the 243? I've never used anything but jacketed bullets for my 243 and 300 win mag and I'm starting to think I may have missed out on a whole other aspect of handloading for them. Ideas?
