SMOKELESS POWDER COMPARED TO BLACK POWDER?
What are comparable loads between smokeless powder and black powder. I have read some reloading charts for a 45-70 gov. It shows smokeless charges that range from 42 gr. of smokeless to 61gr. smokeless. The average charge is 52.7gr. of gun powder for 46 different charges. Is it safe to assume that 70 gr. of black powder falls between a charge of lets say 45-55 gr. of smokeless?
The reason why im asking is, I would like to know how much an inline muzzleloader is equivalent to when loaded with 150 gr. I have seen a couple guys hunt cape buffalo with inline muzzleloaders loaded with 150gr.
Is this any comparison to a 458 win mag?
