Quick and easy - Lee 90055 Lube & Sizing Kit One Kit .452 Standard 7/8" X 14" Threads

I had some lead bullets that were a little too big around and I wanted to put gas checks on them. so I bought this to size the bullets and to press the gas check on them.some people like to make their own bullets well you have to have a way to check the bullets to make sure they will fit your brass and the lube helps keep your barrel clean
