Im looking at my opinions for priming cases but, right now im low on cash. I was considering a single stage hornady with an automatic priming system but, I already own two presses a single stage lee and a turret classic lee. I think my best bet is a used rcbs bench mounted priming system.
I've been happy with my Lee Auto Prime, the press-mounted one. You have to help the last few primers in the tube into place with a pencil, but it hasn't really bothered me. If I remember correctly, it was around $20.
One other thing worth noting, the instructions have primer brand recommendations, I use CCI which is one they say is OK. Best I can tell, for safety's sake they want you to use hard primers.
I have one it works well on large primers on the small it tends to kick them out on floor there are ways to prevent this but it slows the process.
I like the hand held primer tools but my old hands have some problems grip and squeezing after about 50.
I highly recommend the lee auto-prime handheld tool. It is very cheap and gets the job done well. Now, if you are reloading large volume, your thumbs can get a little sore using it. It offers excellent "feel" vs. bench mounted units and you can prime cases while watchin' TV. I will never use a press mounted tool after using this.
The Lee options already listed are great; Auto Prime works good on my turret with either large or small primers. The Lee hand primer works as well on all rifle cases. No need for another press IMO.
I have the dillon 550 B but don't use their priming system Only because I was used to using the RCBS bench mounted automatic primer system. I like it better cause I can feel the primer being seated . You not only can go by feel but view also. After you get your timing and rythym going , doing a few hundred rds. is no problem for me. Then I go to my Dillon to finish off the complete rd. I feel better knowing I felt the primer being seated firmly . But there are lots of people that can do that on a Dillon,.. just not for me.
I've had an RCBS bench mount unit for many years. Get a primer flipper, load the tubes with primers, install the shell holder and away you go. It's easy and fast.
I have an old Lee hand held unit but prefer the RCBS.
