I noticed in the latest Handloader that Mike Venturino did a story on the .45 Scofield. He likes the RCBS 230 grain LFN and among other loads, 4.3 grains of Bullseye. This sounded more than familiar to me, so I looked in TFS 193 May-June 2008 at Ed Harris' article “Cowboy Slugs Convert .45 ACP into a “Smokeless Schofield".
Ed likes the Saeco #954 or RCBS 230-LFN in a .45 ACP converted Pietta 1858 Remington copy. Guess what his most accurate load is? Yep, 4.3 grains of Bullseye. He did go up to 5 grains with this bullet, but settled on 4.5 grains as giving the same velocity as the original Scofield load.
Mike tested a number of other powders, and four other bullets. It's just interesting to me that he came to a very similar conclusion with regular .45 Scofield brass.
