Product Information

Formerly known as 3N18, the N340 is a true multipurpose powder, developed originally for 9 mm and shotshell loads. This pistol powder is one of the most popular powders in the Vihtavuori N300 series, and it can be used for a wide variety of calibers and bullet weights, making it the perfect partner for all kinds of reloading purposes. The N340 is used especially for medium and large caliber pistols and shotshells with medium and heavy loads.

N340 is a tubular powder type with grain dimensions of 1,0mm length and 0,8 mm diameter. Exactly the same grain size as with powder N320, N330 and N350 – only the porosity of the powder changes.The burning rate of the N340 is at the medium scale of Vihtavuori handgun powders – and as with powder N320, with N340 extremely clean burning and no residuals is guaranteed.


WARNING: This product can expose you to chemicals including N-Nitrosodiphenylamine and Di-n-butyl phthalate, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to -

Fine 10mm Powder

By Billy B. on Apr 11, 2020
No, it doesnt give the highest velocity but wow is it consistent. Vhitavuori powders are also, hands down the cleanest powders on the market today. I loaded about 450 rounds of 10mm for my Dan Wesson Silverback 10mm in new Starline brass with Federal 205 LP primers using x.xgr of this powder (.xgr over their listed max) under 180gr Federal HSTs and according to my chronograph am getting 1085fps avg and 8fps SD, consistently. I really love Vhitavuori powders. Yes, I know, they're expensive but the consistency, and the fact that the gun still looks like it was just cleaned after many rounds, is worth it to me. Finally a recipe I know what I'm gonna get. And, with the HST bullet, which seem to favor slightly lower velocities for reliable expansion, its wonderful.
I also load a 3100+ fps xxgr load for my ARs with the N530 powder. Talk about a sweet load. The copper eraser compound works great, especially in rifle applications.
I wish I could afford to shoot V powders exclusively, I surely would.
