I don't load for any rifles except .223 and M1 Carbine, I do load .380's for a close friend (actually he loads I carp and correct) I do load 9mm, 45 ACP, .38/.357 and 40 cal. I didn't spend anywhere near $250 for caliber conversions for my 550B...I have powder measures on 4 ca heads but one is Dillon the other three are Lee Auto Drum....works great, accurate within a tenth of a grain, and about $28 for the measure..Dillon measure moves from 45 to 40 cal, others are dedicated. I also have a Lee Auto Drum on a companion Lee Turret for those calibers that don't get the full Dillon treatment. At the present, I am toying with 9x18 for a favorite grandson..trimming 9x19 isn't that hard, and we both are learning something new.
