I'm fairly new at .45AR shooting (have a SW1917 & a Webley), I prefer .45AR to Moonclips too, but found the SW1917 just doesn't like ANY lead bullets I've tried (tumble/sideways @ 25yds). Good luck, & post any new ideas you come up withLike many old, vintage .45 revolvers, your 1917 may have an oversize bore. If you're shooting bullets intended for the .45 ACP autoloader, you're not getting a tight fit and that is murder on accuracy. Slug the bore and measure to find out what you have, and measure the cylinder throats as well.
If the bore is much over .451" that is part of the problem. When you measure the cylinder throats, drop a bullet with your fingers into the chamber from the rear. If the throats are right, the bullet will drop right through with a slight nudge from your finger. If they let the bullet drop right through with no resistance, they are oversize. If you have to tap them through with a dowel and small hammer, they are too tight. That will contribute to the problem by swaging the bullet too small, so it tends to rattle down the bore rather than grab the rifling the way it should. Combine that with an oversize bore, and you'll be lucky to hit the side of a barn from 5 feet.
Tight chamber throats can be opened up a bit, and if the bore isn't too oversize you can usually find cast bullets that will fit it fairly well. In any case, use Auto Rim cases, so that you can get those bullets to fit right, as they are more flexible than the ACP case in those old revolvers.
