Ok so say it feeds fine would there be a benefit to use that over a standard ball roundDepending on the pistol I'd want to be VERY sure SWC fed cleanly in it.
so question referencing the pistol ammo, I think Darryl stated about use of 45 ball in areas where you couldn't use hollowpoints. would there be a benefit to use a semi wad cutter out of a semi or would a fmj be better?
First, I would avoid FMJ ball in any caliber and it would be a last resort. With that said, if I am limited to non-hollowpoint ammunition, I want the biggest caliber available and the most efficient round that will reliably function. Optimally, ammunition like a filled cavity, truncated, or softer tip would be best for function versus FMJ ball. If it has to be FMJ, then yea, .45 over 9mm.
