Hi guys! I am looking for some loads for a 405 gr hard cast bullet from my 45/70. The bullets are not gas checked and I've already made the mistake of loading too hot and leading the barrel (48 gr of rl7). I have Rl7 and IMR 4198 on hand but any info would be great. I'd like to make up some plinking rounds as well as some stiff ones that won't lead the barrel. Also I slugged the bore and came up with a diameter of .456". The bullets are .459". Too big? Any input would be greatly appreciated, thanks!
