Good Loader. I've got well over 10k rounds through mine. I've loaded 9mm, 38spl, 357m, 44spl, 44mag, 45acp, 45 colt, & 454 casull in pistol, & 30-30, 308, & 223 in rifle. The primer seating lever broke doing the tough 223 deprime/prime, because i just put the brass in & cranked it. I did over 800 in a couple of sittings before it finally broke.
I tried the bullet feeder in 38 cal, but it didn't work well enough to mess with.
The biggest problems i've had were with the primer feed. Some get smashed or turned, or miss completely. I find after doing a hundred or more, it gets dirty & needs cleaned up. It is fussy about setup, but once you get it dialed in, you can just crank the handle & spit out good bullets. I'll stop every 10-20 rounds & make sure the primer is good, or that the crimper is right, but usually it can just crank them out.
I even used it for some 410 brass reloading, to deprime, prime, & drop powder.
I had the primer lever bolt part crack on the ram, after ~ 8k rounds or so.. probably my fault for pushing too hard when i knew there was a problem. But Lee replaced it. I had to mail in the old one, & they sent me a new one without charge.
I keep it greased up, & all the sliding parts clean & filmed with some white lithium grease. I watch the case feeder, to make sure no brass is upside down, then the primer feed, to see it's feeding right, & occasionally the powder feed, which is the most dependable part.. never a hiccup with it. The bullet seat is easy, after placing it on the case, & i usually crimp in the last station, for most calibers.
I have mine bolted to a plywood base, & that on a table, which wobbles a bit. But i find that it helps with the powder drop. When i had it on a more solid base, the flake powder wouldn't always drop consistently. With the less stable table, it shakes a bit more with each crank, & drops the powder more consistently. It was not that far off, anyway, but i measure it now & then & would see a .1 or .2 variance in grain weight. For my non critical range shooting, it has not been a problem. Ball powder drops more consistently.
I might be due to replace the primer feeders, but everything else is still tight. The case holders turn fine, & the ram slides evenly. it is nice to just drop in the loaded turrets, with all the dies in place & adjusted. I just check them check the powder load & a couple of bullet seatings & crimps, then crank away.
I have gotten cranky in my old age, & this thing proves it!
