Found some vihtavuori n-120!

[45r]

Tried some noe 150gc bullets over 19 grains n-120.
They shot very good at 1836 fps average in the seekins 10.5 inch barrel.
ES was 29 fps.
Got one inch 7 shot groups at 60 yards.
Had to settle the powder since it's a compressed load.

Drop tube and a slow pour into the case will help a lot

Tried the N-120 in the 8.3 inch barrel and it shot the first one 2.75 inches high and the next 4 into a half inch dead center at 60 yards.
It didn't seem to like N-120 last time I tried it.
Load was 10.5 grains over Noe 311247s powder coated with CCI 400 primers.
Average fps was 1016 with an ES of 14.
Glad I tried it again in the BA barrel.
This powder shoots very well and 2 pounds should last a while.

Even though my subsonic N110 loads are quieter, cleaner and have tigher SD/ES, I can't get them to group as well as my N120 loads (seems to get a lot of unexplained flyers). I use 10.3 gr N120 for SMK 240 @ 2.26 coal and 10.3 gr for 200 Lapuas FMJBT @ 2.25 coal. 980 fps +/- 10-15 for both loads on a Noveske 10".

I like Viht 110 and 105 also but this powder shoots more consistent and stays in the 1020 to 1050 fps range easier for me.
I like that you can turn the gas way down and use an H-3 buffer also.
Brass lands in the same spot with a smooth recoil impulse.
Pretty quiet also.
If Viht N-105 was easier to get I'd use it for the most quiet loads but it doesn't bug hole sometimes like N-120.
!0.5 grains N-120 with the CCI 400's at COL 2.185 seems to be hitting the sweet spot.
I've made a bunch of them and might stay with that load from now on.
