    Targets for load development

    I know, I know, there's a million choices already. But I wasn't 100% happy with anything I've found yet. I had the time this morning, so I drew one up.

    Question about harmonics and OCW tests

    Hi Guys, Question here. I am wondering about OCW tests conducted using different seating depths of a projectile. Let's say I want to do an OCW test, so I load up my rounds and set the ogive to base length to a certain distance (we'll call it X) using my micrometer die. Then I go shooting...
