Is that what you do?I got the hornady tool, but if you don’t have the tool it’s another option.
When I get my gun back, and after I get charge weight dialed in, I was going to try the same. Jam point, lands, etc.
The seating die my buddy has will be a PITA to vary the different seating depths though. If/when I get to this step, will look into the dial seating dies.
It’s going to be hell trying to change seating depth with a non micrometer seater.
If you want to use the mag you are subject to that limitation and seating depth may or may not be an option. It’s also bullet dependent. Some like to be close to the lands and some don’t care.
Redding sells a micrometer seater add on if you have their regular seater die. Another option.
