OK....Its been years since I've owned a 458 WM....went and looked at what powders I have and really don't have the best to use what I've read hear....AA 1680 and IMR 4198 but have pounds to burn....only bullets sitting on the shelve I'am going to shoot are Hornady 250 gr. Flex-Tip for playing around with paper and Cutting Edge Bullets 258 gr. for hunting.....
Was thinking that in Ohio you can use any 35-50 caliber straight wall cartridge for deer hunting.....458 WM fits the bill....

What are some loads for both powders ?
