Some years ago there was a half-jacketed bullet available to reloaders. The manufacturer had a warning on the box to the effect that these bullets be loaded to exceed a certain minimum velocity. the reason given was that if loaded to very low velocities, the lead core could separate in the bore, leaving the jacket behind, and thus cause a bore obstruction.
Some ammunition was loaded with these bullets intended for use in short barreled revolvers, and a cautionary note placed on the box. This appears to be the source of concern for ammunition intended for short barreled revolvers. But factory loaded ammunition, by the major manufacturers, is loaded within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications.
