All of the above sound reasonable...I load my Carrolls 200 lswc to 1.255 and my Bul-X 185 lswc to 1.240.
I just switched my 185 gr. bullets to Bull-X because they make a longer 185 which means I can have a longer bullet than the short 185s that are so common. My two Kimbers, My Springfield HiCap and my Charles Daly all seem to love this Bull-X length. BTW, this will seat the bullets within an RCH of the shoulder, but I haven't measured it.
