Is there any shotgun powder that should not be used in handgun loads. .357, .38 special, .45 Colt, .45 ACP, .44 Mag.?
I just purchased some V V N3SM that is a sort of a square flake type that seems to go through a powder measure with more weight consistency than Unique. It also is a nicely bulky for its charge weight.
At $25.00 for 5 to 6 pounds I could not pass it up. An unopened 4 pounder and a couple of pounds in an opened jug.
The guy that sold it to me said he used it in 20 gauge loads. I can’t find any information about it on the V V site and it is not listed in any burn rate chart or loading manual that I can find.
Since it is used in the 20 gauge its burn rate may be somewhere around PB or green dot. I figure about 4.5 grains in .45 ACP/200 grain SW and if it does not cycle the action to go up slowly.
Bad Idea?
