i inherited a remington hepburn in 40-70 ballard.it was my grandfathers,i have had it for a while and decided to get going on making it shoot.i never recieved any cartridges,but i plan to form them from 444 marlin.the head dia.is smaller but will still push back with the extractor.i am not going to load black powder,looking for moder replacement suitable for that cartridge.any load data, reloading components or equipment you may have would be of interest.i plan to hunt deer this fall with this rifle.i already have access to a bullet mold,but still need dies and if anyone has it,i would like to procure some 40-70 headstamp brass.thanks,adker
