Default A question for VihtaVuori users

I was reading the particulars, and I'm tempted to order some for my autos.

The description says it's a single base extruded powder. How does it meter through your powder measures? Does it resemble extruded rifle powders in appearance?

I only have loaded N320. Meters fine through my Uniflow and my Dillon. To me, it looks like a smaller version of the extruded rifle powders I have loaded with, smaller in length and diameter than the rifle powder and for my loads it burns very clean.

I've run some N310, 320 and 350. Burns very clean and consistently. Not very temperature-affected for burn rate. Meters very nicely. Works better than many powders for lead bullets.

I've used 320-330-350, all about the same grain size. It is premium powder for sure - clean, consistent and not temperature sensitive - one of my favorites when I can afford it but it meters like gravel from my old RCBS hand throw. Sometimes I can get a nice smooth throw and other times it grinds. Not as bad as 4064 or other IMR powders though.

I've used 3N37 in 9x23 Winchester and N135 in 7.62 Nato. Both meter and burn very consistently. VV has lots of free load data online too.

4.1 grains of N310 and the Nosler/Zero 185 grain JHP is THE 50 yard load for my 1911s I use for bullseye shooting. Groups inside of 2" off a rest on a good day.

I use N110 for .357, and echo most of the above comments. It is like the extruded powders for rifle rounds, but the sticks are shorter. It meters pretty well through my Uniflow, but not quite as well as a finer powder like H110. A very clean-burning powder also.

I shoot bullseye & use VV powders in several calibers . For 45acp target loads N310 is hard to beat , 230 ball ammo N320 is great . N340 & N320 also work fine in 38 special target loads too . It cost a bit more , it's clean burning & outstandingly accurate . If you shoot for points , what more can you ask for ?

I've been considering giving N350 a try, so is it difficult to meter in an RCBS Uniflow?

Jitterbug, I second what 125JHP writes also for N340. Very good but very hard to meter in my Hornady powder measure.

Mind you, the problem is not so much that you get unacceptable weight deviation; rather, it's a matter of very stubborn, and unpredictable, bridging, which however does not - at least in my experience - affect weight repeatability. A real nuisance, though.

That said, I use N340 for all my 45ACP 230 and 185-grs loads, all my 38 Sp heavy bullet loads, as well as all my 357 Mag lead or plated loads, with oustanding results.

I have used N320, and it is excellent. I use a Dillon powder dispenser with the smallest powder bar. In a progressive reloader .1 gr variance target is tough to measure or improve on. I have found it to meter the same as W231. It is very clean burning. I have moved on to AutoComp, which is cheaper for me.

Well that's a bummer if N340 is difficult to meter.

I don't have much use for a crunchy high end pistol powder. I save 800x in 10mm for that task and hand weigh only.

Sounds like there might be a big difference in metering 320 vs 340?

231 flows through my RCBS Uniflow like water, so far it's been a good powder with my limited usage in .44 Mag.

I've used both & had no problem metering with a Dillon measure . If using a drum type measure any non ball / flake powder is going to have cutting issues .

Yeah, I have used 320, 330 & 350 in a drum meter and they all are rough. Under a microscope I cannot tell the difference in granules between them so the burn rate difference must be the coating used.

I used N320 in my Dillon 550B. The powder metered exceptionally well.

N310 looks like a tiny stick powder. I only used 1# of it, but I never had any metering problems in my Hornady LNL-AP.
