I've played with them some...I think they are sort of finicky..

I have them in 20 cal, 6mm, 6.5 mm and 30 cal...

They are usable on a variety of chamberings, they just have to be set up for them...

I've played with them for a cheap alternative... but so far I really haven't impressed myself with them a whole heck of a lot..

but then again, I don't care much for Hornady's regular dies either...my preferences are RCBS, Lee and Redding...
