Yes, I am fairly new to reloading so I am hoping to get some knowledge from you guys here I do understand what once fired brass IS but I'm not quite sure what the benefit is. IS it more accurate than new brass because the once fired has taken on the dimensions of your particular chamber or is it a slight increase in powder capacity...or is it something else? Furthermore, when you do have once fired brass, do you need to buy a custom die to maintain the dimensions? Finally, you now have a mountain of once fired brass and you need a new barrel....what do you do with your brass? Thanks SO MUCH FELLAS!
