I presently use my RCBS single stage press (green one) to seat my primers. It works fine, but is a bit slow. Now that I'm shooting more, I'd like to upgrade to something faster. What do you fellas use (or not). Would appreciate comments both ways.
The ergonomics of each of the hand primers depend on individual fit, but none of them are difficult to use.
Having said that, in my experience, the Lee has the best tray (primers flip easieist), the Hornady has the best ergonomics (fits my hand best and stands by itself), but the RCBS Universal is the one I use.
The RCBS does not require shell holders, so all my shell holders stay with the dies they belong to. It has never jammed a second primer at the ram, never flipped a primer at the ram, and never flipped a primer sliding them back from the throat into the tray.
Finally, as you bring the ram up to seat the rpimer, a metal bar slides in between it and the primer tray with the intent of shielding those primers from incident. I've not tested this lol, but it looks like it would work. Because of this feature it takes 2-3 minutes to change primer sizes - mostly spent finding the other parts lol - so being incredibly lazy I set up one for small and one for large like Scooter123.
Bench primers are terrific for those who can't or don't want to squeeze, who don't mind the handling of primers required, and who don't mind spending more time right at their bench.
