I have foster with the micrometer but these rcbs came in the lot when I got the reloading stuff. I have good results but since I am adding new bullets for the 30-06 I find this easier to set up.
I seen the run-out tools and made my own version but it did not seem to work too well. So far I am just shooting up to 200 yds for hunting so I am not too worried about it but I have thought to someday upgrade to a die with a micrometer.
stangfish, for some time I did many things but since I cant find a place to shoot over 200 yds im no longer weighting components and the such. So far I keep my components withing my not so tight standards, try to keep everything constant and I get really good numbers in paper but the test will come if I ever start shooting 300 and over.
