I started out using using the primer on my RCBS Rock Chucker, I used it for a long time. I then got a RCBS hand primer. I like it real well. The Lee is supposed to give you better feel and there are a lot of folks that use them. I liked the RCBS because it works, it uses the same shell holder as the case head, I have "feel" with it and it seems rugged. But I am still using that same Rock Chucker press so I am single loading still. However, I do every thing but size and seat bullets some where else. I push out the old primer with a cheap Lee press and clean (yes, I said clean) the primer pockets on a RCBS prep center. I guess if I were using a progressive press I would use it to prime also. What is the point of having a progressive if I did not do every thing on the blasted thing? I like single shot rifles and revolvers so a single stage press sort of follows, but if I were shooting competition and were loading 500+ rounds a week, I would have one. I do not see the point of getting a separate primer if you are using a progressive press, but if you are still using a single stage press, the Lee (cheap) or RCBS makes a lot of sense. The system CW is talking about is a great system, but like he said it is expensive and then you have to buy your primers in those strips. Right now getting any primers are hard to get, let alone buying them in the strips - but they are nice. I can not image they have any feel to them however, but I have never used one so what do I know? Bottom line if you are committed to your progressive, I do not see that a separate primer is any advantage only some thing to slow down the process. Good Shooting and Good Luck
