I'm sorry, I somehow missed this thread on one of my favorite topics.
I've only used the 200 SWC with micro-grooves, but it should be similar.
These bullets are accurate and I've found the Lee moulds can be easy to use, especially with 200+ grain bullets. Steel moulds are more forgiving when the proper temp range is reached, but check the price.
There's no need to size the bullets unless the mould drops them out-of-round or really oversized. Most Lee moulds I used drop 100% wheel weight metal at 0.002" over the stated diameter (except the one I WANTED to be oversized).
There's no need to harden bullets for the .45 auto with water or an oven. I've tried it and it's a waste of time.
Lubing with liquid alox (I use the zip-lok bag method) is extremely easy. Once lubed just dump them on wax paper overnight.
The drawback is the entire bullet is covered in lube. While not really soft, it will get on your hands and all over your brass if you toss freshly loaded rounds in a container until you box them or whatever. Wiping the stuff off of the exposed bullet is an option, but a very poor one.
I've used them and was fairly careful as I loaded them so they didn't come into contact with the cases of other rounds. Using them in competition was no big deal, but any rounds in dropped partially filled mags or the round that hits the dirt after clearing the pistol will require a wiping. Not a big deal, but it's a minor drawback.
As a vain reloader I tired of the ugly appearance and the slightly slower loading (due to added handling). I started using a lubrisizer, but the pure boredom of it has made me think I might just dust off that Lee mould once again. Lubing 2000 bullets in a lubrisizer is no picnic, while lubing 2000 with liquid alox only takes a few minutes.
Using liquid alox and a Lee sizer is pretty easy if you find that sizing is needed. Ignore the instructions and size before lubing. A person could probably size 1000 an hour with little effort.
I've never found the liquid alox to be especially dirty compared to "normal" lube as far as the gun is concerned as long as you normally clean roughly every 1000 rounds.
The 6 cavity moulds are different than the double cavity moulds for sure. I'd much rather cast using a pair of double cavity moulds than use a 6 cavity mould. It seems like one or more cavities will nearly always drop rejects unless your standards are low. I've heard positive comments from some people, but I won't buy any more of them.
