Just started hand loading .40 S&W using 165 gr jacketed round nose bullets using Power Pistol powder this weekend. Is it me or does it give an impressive muzzle flash and somewhat louder report compared to say Bullseye powder which I use for my .45ACP loads. At first I was questioning my loads which were at 7.2 grn and moved them back to 7.0 to be safe. My Speer manual has this setup with 7.0 min to 7.8 max so I am well within tolerances. It's not a big deal, just caught me off guard at our local indoor range. Anyone else doing a similar load setup with the same results?
