Just getting set up for loading my 45-70 and will be using some already fired Remington brass as well as some new unfired Starline brass. I've never used new unfired brass to reload (just spent cases). I was wondering if I need to put the new brass through the resizing die or is this just going to be a waste of time since it has never been fired?
Thanks, Any advice on loading this caliber will be apreciated!
