Ive used a bunch of lee equipment, auto prime, pro 1000, loadmaster, moulds, dies etc.
I've sold off the p1000 and the loadmaster, but alas I miss the p1000.
It's one of the best presses I've ever used. even compared to the dillon 650 I use now.
The p1000 is a very good press but it only hold three dies and that is the reason i sold it off and bought a loadmaster. The loadmaster had to go because of the primer seating and I wanted a faster casefeeder.
As stated above an engineering degree helps when you tinker with a lee progressive, especially the loadmaster, but its all good and fun as the journy is 80% of the experience.
As for the moulds I take a lee six-banger any day and i weep when I have to pull out my lyman 4-cavs. All steel moulds I've tried leave me with a searing pain in my hands and arms after a full day of casting. I cast one full week per year to get me my bullet supply for the rest of the year.
In my current setup in the 650 I still use two lee dies as I haven found anything better that I can afford. A factory crimp is a must for 9mm in my book and I use a lee bullet seater with a lee bullet feeder. I use this setup as I need a high throughput and don't have much time to put on reloading.
There are many that say "lee is ****". But I've heard many, many horror stories with other brands as well. So I tend to take those stories with a pinch of salt.
Lee may have some bad luck with their quality control but all the gear I've bought the last ten years have worked flawless. The real equipment killer have been little old ham-fisted me.
I know a die hard dillon 550 fan that haven't been in the same room as a lee press since he threw out his lee single stage like 15 years ago. Even he has admitted that a lee turret gives a truckload of press for the buck, and he bought one about a year ago for his low volume rifle reloads.
To sum my rant up:
Lee isn't all good or bad, bot noone else is either.You have to try the stuff for yourself and see if it fill your needs. And a good thing with all the lee haters out there is that they end to sell off their equipment for almost nothing, for me to buy and save even more money. I tend to be very selective in my reloading habits, with everything involved as powders, dies etc.
I want the stuff that gives me maximum bang for the buck, nothing else will suffice.
Yes I'm a cheepskate and a brassbuzzard, but this is what keeps my shooting habits going without another mortgage.
