I just got a old lee loader "kits" from a friend, it basically allows you to de prime, prime, crimp. The thing is it does not come with a die/part to resize the hull. I plan to primarily melt/reload slugs and recently replaced the extractors on my mossberg 500. Is a brass resizer necessary? (meaning is this kit alone enough to do the job) or should I plunk down $50 for a lee load all ? Thanks in advance.
