When I was in college in 1967, being on a tight budget, I bought a Lee Loader in 8mm for my surplus Mauser. A few years later I got another one in .45 ACP, plus a Lee Lead pot and .45 bullet mold. All through the years, I added more and more Lee Loaders until I needed a caliber that they didn't make. Then, I bought regulay Lee dies and an Anniversary press. I ventually replaced all the Lee Loaders with dies, plus added a second press.
Except for a 1970 vintage RCBS powder scale, I'm 100% Lee. That old .45 ACP bullet mold has cast thousands and thousands of rounds and irs still as good as new. I've replaced a few incidental parts, but have really never ahd a provlem. I load and cast 5000-6000 rounds a yhear.
I'm not associated with Lee, but I sure wish I had bought their stock years ago.
