These shoot very well from all my pistols and carbines, barrel lengths from 3-16 inches. It does leave a slight blue residue in the barrels but does not require any heavy cleaning to remove. I've shot hundreds of these without any build-up and no accuracy problems, however the grouping visibly opens up slightly past 75 yds compared to copper coated/plated. Definitely beats shooting plain cast bullets. Only thing to pay attention to while loading is to make sure you flare the case mouth slightly to keep from peeling the coating. Overall... great bullets. Best online value I have found.
Awesome target bullet
