My Taylor's Uberti Lightning Short Rifle has been modified by Longhunter to release only one round at a time from the magazine. There is another element though, beside the advice about minimum COL and staying with 357 cases, and that is the shape of the bullet. My RNFPs are not consistent in loading, so I have gone to a TCBB from Penn, who has that shape in the 158 gr I use to keep velocity down I don't "race" the gun at 73 years old but do like the style points for shooting the Lightning. If I can get through stages without a functional issue, fellow cowboys might resist the well-intended urge to advise getting an 1873. I need to shoot what I own, at least for now.
Another thing about bullets is that the gun hangs up on any leading band, so I was crimping over that on the RNFP. The TCBB doesn't have any shape except taper ahead of the crimp groove.
