Thanks, LG. Do you suggest a FILL material to hold Unique over flash hole?
On crimp, am using full length RCBS 454 die set for good bullet/neck tension plus Roll crimp too. But also have a Lee Factory Crimp die, do you think needed?
Plus have a Dillon 45 colt Taper Crimp but dont remember if it finishes with a Roll Crimp, thinking it may not, but it looks nice, ha!
May first try 255g medium-hard cast, should seal good. But have thin plated 260g in stock too, dont want to over Crimp these particular plated bullets. Will keep your bullet link suggestion in my log though, for sure.
