I, on the other hand, have used the press-mounted RCBS priming system for a long, long time, and I can't imagine priming any other way. It works fine for me, and after this long, I can "feel" the primer into the pocket pretty accurately. The only hassle is having to change the little primer plunger - what IS that dohicky called? - when I switch from large primers to small or vice versa.
If God didn't want us to own guns, why did He make the 1911?
The RCBS hand priming tool is the way I do it. I tried the Lee tool but it doesn't hold up to serious use and I don't care for the "thumb only" method or a cover that falls off with little reason. The Hornady tool is a pain to change shell holders and primer sizes, plus it doesn't work as smoothly as the RCBS unit. The only negative with the RCBS tool is that the priming pin(??) will fall out if the tool is inverted.
I could see where the bench mounted unit could be OK, but I've never used it.
I have been using Rock Chucker master kit for about 9 years now. It came with the primer feed combo and I'm always happy how it works. I have 2 sets of the primer feed, small and large, so I don't have to change that little plunger.
For handgun rounds, it will expand the case mounth and prime in the same step. It saves time (for single press reload) as well as giving me a positive feeling during the priming.
Of course, with the hand priming tool, you can do it while watching TV. If you're not in a hurry, I'm sure it works as good.
I kinda like the handheld tools. Choosing between Lee and RCBS is strictly a matter of preference. I have both, and I think the RCBS is the higher quality tool. Problem is, the Lee seems to fit my hand better. I guess that's because I started using the Lee unit long before RCBS made a handheld priming tool. I reckon ya pays your money and ya takes your choice. Happy shootin'.-TR
