I've been loading for 30 years, honestly don't know anyone who actually shoots more than once a month who doesn't reload. I've never known anyone who uses his press to prime cases. I ground my attachment thing off my T-7, and removed the primer parts from my coax as well, I have cute little brass screws on the top of my rams instead.
Hahaha, just the opposite for me and I know a lot of reloaders. I'm no noob here either, but the question is why?
I can see if you like to do some reloading in front of the TV and want to kill two birds with one stone, or perhaps you enjoy priming your cases in your nice music room, while listening to a Mozart piano concerto...sure.
I can tell perfectly, whether a primer has been seated fully, or not, and whether the primer pockets are loosening up, or still pretty firm and at least with the hand primers, I'm not causing my fingers to become prematurely arthritic, lol. Also, it can't be any faster and it's certainly more money to spend on the equipment, at a minimum.
I think the key to seating a primer properly, isn't in the method, but making sure that the primer pockets have all been uniformed as best as possible.
Anyhow, if we all did things the same way as each other, it would be a boring world.
