I have used all the old Lyman suggestions,Red Dot, Unique and 2400 and they all worked pretty good for me. A few years ago a guy was really pushing blue dot, he even had a web site. I tried it and it worked very well. Seemed like I couldn't find any loads that didn't shoot pretty good, so instead of testing for accuracy and choosing whatever shot best, with blue dot it was more a matter of just choosing what velocity I wanted.
I don't think the web site is around any more, I haven't run into it, but maybe I'm just not doing the right search.
