If that works well enough (i.e. works the bolt and is good for 150+ at 600 which is about what I scored last time I shot M72 [had gun trouble]), I am done with load development (for now). At this point in my shooting career, I will be better served by getting out and shooting the Course rather than spending who knows how long tweaking handloads.
Other question: Is there any reason to go with one brand of gage over another?
I like my rcbs. If you are serious about resizing to the minimum spec, remove the gas lock screw for your reference cases else the violent extraction stretches them. This phenomenon led me to believe I had too much headspace when I first got the rcbs case mic.
