Use data shown for a similar shaped cast lead bullet. Quikload is a great tool, but your OACL with a 200 gr. RN isn't going to be 1.275" which is max. cartridge length. Do you know how to determine OACL for YOUR pistol? If you loaded to say 1.250", that's not that much OACL variation for the lower operating pressure of the .45 ACP using the lower charges of N320 shown in JRH6856's QuikLoad graphic, but there should be cast lead load data available directly from the Vihta Vouri manual or load guides.
