Im building a 20 practical and my Criterion barrel is picky as hell, I currently have a set of RCBS AR-15 223 dies, regular RCBS 223 dies and a full length sizer Redding type S die and NOT ONE of these dies will get close enough to the bottom of the brass to reliably feed. I trimmed .010 thous off hte shell holder and no difference and trimmed another .010 off the die no go there also....Ive read in a few places where the LEE die sizes even further down than the small base circle RCBS die, Also the Small base RCBS die set is only 4.00 more than the Small base sizer as a single die, is it the same die or a different one because its in a set....I had an AR10 that i HAD to use RCBS small base 308 die and thats the only thing that rifle would eat....If anyone has any advice on this Im all ears Im going broke on this project....
