Try Vihtavuori N320 in your .45 ACP Pistol

VV N320 for .45 ACP

VV N320 for .45 ACPMan does not live by long-guns alone. We know that many of our readers own .45 ACP handguns and load for this extremely accurate “classic” cartridge. When selecting a powder for the .45 ACP, there are many good options. All the major powder manufacturers make propellants with appropriate density and burn rate characteristics for the .45 ACP. Popular choices include: AA #5 (Accurate Powder); Bullseye (Alliant); Clays, HP-38, and Titegroup (Hodgdon); VV N310 and N320 (Vihtavuori); and WW 231 and WST (Winchester). We’ve tried all those powders in a variety of .45 ACP handguns. When we consider all the factors that make for a good pistol powder, we think N320 is one of the best available propellants for the .45 ACP. Vihtavuori N320 is very accurate, it meters well, and it burns clean, with minimal smoke and flash. If you haven’t tried VV N320 yet, you should.

Pros and Cons of Different Powders for the .45 ACP
This Editor has personally tried out eight or more different powders for the .45 ACP. Bullseye works but it is very dirty (both smoke out the barrel and sooty powder fouling on case). Though it otherwise burns clean, Titegroup leaves a singular (and nasty) high-temp flame streak on your brass that is hard to remove. AA #5 is a good choice for progressive press newbies as you use more powder so a double charge will (usually) be obvious. I like AA #5 but N320 was more accurate. Clays burns clean but some powder measures struggle with flake powders like this. WW 231 offered excellent accuracy and metered well, but it kicked out sparks with little pieces of debris that would hit me in the face. Who wants that?

I personally tried all the powders listed above with lead, plated, and jacketed bullets. After testing for accuracy, consistency, and ease of metering, I selected VV N320 as the best overall performer.

Vihtavuori N320

  • No powder tested was more accurate (WW 231 was equally accurate).
  • Meters very well in all kinds of powder measures.
  • Produces very little smoke from muzzle.
  • Does not put nasty burn streak on brass like Tite-Group does.
  • Low Flash — you don’t get particles and sparks flying out like WW 231.
  • Cases come out from gun very clean — so you can tumble less often.

Forum member and gunsmith Michael Ezell agrees that N320 is a good choice for the .45 ACP. Mike has also found that WW 231, while accurate, produces sparks and a large flash. Mike writes: “I first started using N320 after my first night shoot, while shooting IDPA/IPSC matches. It was astonishing how much of a fireball the WW 231 created. I was literally blinded by the flash while trying to shoot a match. As you can imagine, that didn’t work out very well. I went from WW 231 to N320 and never looked back…and the flash from it was a fraction of what a kid’s sparkler would give off. I have nothing but good things to say about [N320] after using both. Night shoots are a real eye-opener! When it comes to a personal protection… there is, statistically, a very high chance that if you ever have to use a gun to protect yourself or your family, it’ll be in the darkness[.] Being blinded by muzzle flash (and deafened by the noise) are things that should be considered, IMO.”

This Editor owns a full-size, all-stainless S&W 1911. After trying numerous powders, I found VV N320 delivered the best combination of accuracy, easy metering, consistency, clean burning qualities, and low muzzle flash. My gun has proven exceptionally accurate using N320 with bullets from 180 grains to 230 grains — it will shoot as accurately as some expensive customs I’ve tried. At right is 5-round group I shot offhand at 10 yards with my 5″ S&W 1911. The bullet hole edges are sharp because I was using semi-wad-cutters. Rounds were loaded with Vihtavuori N320 and 200-grain SWCs from Precision Bullets in Texas.

Looking for Vihtavuori N320 Pistol Powder? Powder Valley Has It.

N320 Vihtavuori powderPowder Valley just announced it has received 120 4-lb kegs of Vihtavuori N320 powder. This stuff has been hard to find lately, so Powder Valley suggests: “Get em quick. They won’t last long!”

We know why N320 powder is in high demand (most vendors are sold out right now). This is a truly outstanding propellant for the .45 ACP. It is very accurate, burns clean, and it meters well from progressive presses. This Editor has tried a dozen different powders for my .45 ACPs and N320 is my top choice for 180-200gr bullets. Nothing was more accurate, and N320 burned cleaner (with fewer sparks and unburnt particles flying back) than WW 231 (which is also very accurate).
