I'm not bashing LEE products, I have plenty and will certainly buy more. I guess I'm just venting a bit.
I started loading for 444 Marlin last month and ran into my first issues with LEE products. I'm a budget reloader so my bench almost looks like a commercial for LEE since I've had nothing but good experiences with their stuff. I bought a 3-die set, a shell holder, and a shell holder for my hand primer through Amazon. Everything showed up and looked perfect. When I got started, the first thing I found was that the shell holder for the hand primer wasn't holding the case securely. A quick check with the micrometer showed that the slot was cut to .487", where the slot in the press shell holder was .473". Both are marked as #11. I pulled the hand primer shell holder out of my 44 Mag dies and it was also .473". Obviously the new #11 was either machined wrong or stamped with the wrong number.
Then when I put the seating die in my single stage press, I ended up using a wrench for the last couple turns to get the die adjusted correctly. It wasn't buggered up threads, just that it got progressively tighter as the die was screwed in. I wasn't having to really put any serious torque on it, but it wasn't the normal finger action I'm used to with every other die before or since. I ran a brass brush over the threads on the die, a drop of oil, and made sure the press threads were clean. Everything looks perfect. I haven't bothered putting the micrometer to the die yet, but apparently the threads were not cut fully. I have a tap/die set that I believe will fit the die so I'll probably try taking a bit more off it. Regardless, I can use it as is.
I know I could ship the parts back to LEE and they would replace them. But it's not worth it for a $5 shell holder, and the seating die can probably be cleaned up with a few minutes work. Neither of these were show stoppers for me since I was able to get the die adjusted and I had another #11 shell holder for the hand primer. It looks like maybe quality control at LEE isn't what it used to be. No problems in 40 yrs using LEE products and then 2 in one day. Sorry for the venting.
