Thanks Shadow. I was looking at the one that attaches to the gun barrel. They won't let me put a standard chrono past the firing line at the base. Next on my list when I get a few min loads worked up.I use the basic caldwell optical. I have shot it twice and its still running.
I test for a load with good velocity consistency
then i use seating depth tuning to adjust for accuracy.
Look forward to chatting with you about seating depth.
