Lyman 310, Bonanza Lee Ram Prime and mostly Lee Auto Prime.
I started out with a Lee auto prime in 1981 when I bought my RCBS Rockchucker combo. (17yrs using a Lee Loader prior to that).
After a year or so, it developed a few burrs where on the large round thingo which rides against the body and got a bit sticky. I sanded down the offending parts and lubed it with yukky black graphite grease, no prob since. used it to prime many thousands of cases. I have bought 5000 primers many times in all sizes, especially in small pistol. I would have been through at least 20000 large primers and God only knows how many small. Thousands of small and large rifle primers as well. I have never broked a part and apart from the scratchy phase, no prob. The only trouble I have had was from the 44 Mag shell holder. It was faulty and had a small chip fall out of it and then allowed the case to slip out on one side if you wern't watching. I shot it and bought another without grumbling.
The Bonanza was ok, but a bit of a pin to adjust. Good feel though. Soft alloy and stripped out one of the bolts which a friend fixed. Hardly bother with it now as the Lee is so quick to set up.
The lee ram prime is promising and is very consistent with seating depth, but tips primers over if not careful. Real pain, but mine came with two small primer tubes instead of one of each and so I haven't tried it one big primers yet. It should be good with accurate rifle loads, because it it very positive in the depth seating.
I have a second Lee now and have one set up for large and one for small. Best tool I have ever bought, its a shame it doesn't take standard shellholders. Buy t he box of shellholders at the same time if you buy it. I have just about bought all of them over the years.
