I have a S&W 1917 ex military revolver chambered in 45 ACP and have been using the "moon clips" to load it. Since the pistol was designed for rimmed cartridges and not the straight-wall types, I was thinking of purchasing some of the Rimmed 45 ACP brass that is available from Star Line. What is everyone's opinion of the use of straight wall or rimmed 45 ACP cases? Is it worth the expense of purchasing the rimmed cases? Are they easier to use then the moon clipped cases? Do you recommend them?
