I've been reloading for about 6 years now, so I'm still pretty new at it. I have really only loaded hunting rounds. I have always just worked to find what charge weight gave the best groups and seated them to the COAL from whichever manual I got the load from and called that good enough. However, I have started working up a load for my new range gun that I built in hopes of printing the smallest groups I can. I have the charge figured out, but need help on finding the right seating depth. My question is what range of depths most of you cover while testing a load. How much of a jump do you start with? How far into the lands to you go, and in what increments do you shorten or lengthen your seating depth?
