N110 vs N120 Powder

[gomeybear]

Hello,Gents!

Looking for a solid do all powder (both subs and supers) for 300 blackout and been stumbling across the Vihtavuori stuff on several threads.

Which powder from Vihtavuori would be better for all around super and sub use, N110 or N120?

Hello,Gents!

Looking for a solid do all powder (both subs and supers) for 300 blackout and been stumbling across the Vihtavuori stuff on several threads.

Which powder from Vihtavuori would be better for all around super and sub use, N110 or N120?

Rifle ? Barrel length ? Gas port size ?
N120 is generally more forgiving for subsonic cycling.
N110 is cleaner, quieter but may not cycle or hold the bolt open on last round on subsonics. Also tends to run faster (1070-1100fps - I try to aim in the 990-1020 range)

They’re both not the most optimal for supersonic ... I prefer 1680 (although N120 would work, just a tad slower velocity) for 147-155 supersonic and H110 for 110-135s. N110 give great accuracy with SMK 125-135 but at the cost of velocity as well.

That being said if you had to get a do-it-all powder for a semi I’d certainly go for N120 with Hornady 190 Sub-X for sub and Speer 150 Gold dot for super.

AR - I have 8.5”, 10.5”, and a 12.5” barrels all pistol length gas systems. Not sure of gas port size.

Its sounding like N110 is better for supers velocity wise than N120?

Depends on bullet weight. On heavier Supersonic (147-155gr) N120 will do much better velocity at lower pressure than N110.

How about 110-125 grain bullets?

N110 is much better. N120 would have to be heavily compressed and still wouldn't come close to the velocity of N110 for lighter supersonics loads. Could be as much as +200 FPS with N110. That being said, H110/W296 are still a better choice for those bullets and those powders are very easy to find.

Appreciate the help. Do you know approx how much less velocity you get at full fill between N110 and H110/W296?

What bullet?

Not what weight, what exact bullet.

This is the biggest problem with the cartridge, the people that shoot it and load for it.

To get the most out of the cartridge, you need to treat it like it’s about a dozen different cartridges. You have a 200 grain bullet weight differential with a 2000 fps velocity range shot from barrels that vary over a foot in length in 3 or 4 different operating systems.

To answer your exact question.

About negative 150 fps.

110 barnes, 110 vmax, 125 SST, and 125 Speer Tnt loaded to typical book COAL. Ahhh cmon dellet, granted, I agree, I should’ve listed bullet type, but I gotta say you’re being sensitive, the people are the problem!!!???. Anyways.... thanks for the help, hope Coronavirus doesn’t have too many people frightened around here.

Not being sensitive, only truthful, and meant every word.

The cartridge it too versatile and to reach it's potential, needs to be hand loaded with a reasonable knowledge of internal and external ballistics. This creates a huge problem. In general, first posts here include about half the following statements;

New to the cartridge
New to reloading
New to AR's
It won't cycle
It won't group
Will powder "X" work, I have a bunch and don't want to buy anything else
I found these bullets in the shed will they work
I'm new to casting and 17 MOA is the best group I can get at 25 feet, what's wrong with the cartridge design.

Not trying to knock people that come here wanting to learn, only those who come wanting answers.

If that needs explaining, you might be part of the problem.
