I have a Load Master and and Pro 1000. They are O.K. but not great. Sorta like a bicycle who's chain comes off once per ride. Actually not "sorta" - EXACTLY like a bike whose chain comes off every ride at least once.
I use the Load master for 44mag and .45ACP
- Shell feeder GREAT. Just fill the hopper and give a few shakes .
- Primer feeder "magazine" GOOD. Just fill the hopper and give a few shakes and it turns them all right side up. It does get gummed up with loose powder sometime though.
- Primer seating BAD. It relies on the "miracle of friction" for its little arm linkage to operate. If you lube it with STP (a very thick oil) it works - kinda.
The most common mode of failure is upside down or sideways primers being seated. It's been a while but I'd say it fails me about 1 out of 50 times.
I'm surprised at the complexity of the Dillon case feed (mechanical vibrating hopper isn't it?). Given how well the simple Lee one works. I wonder if Lee has patented it or something? Same thing for the primer hopper.
Tim, If you are the kind of guy to get pissed off at poor design you might want to give the Lee a pass. If on the other hand, if raising your children has given you the patience of a saint, the Lee will work fine.
