VihtaVuori Powder Discussion

[Retired shooter]

I am just looking for the 2750-2800fps area with the ARC in my 26" bolt gun with 110 ATips. Maybe I'll pic up a pound of N540 and try it.

I am getting average 2750 fps with 110A tip using Leverevolution 26 in barrel, gas gun. FWIW.
To all a good day.

Yeah I get 2775fps with CFE223 but was looking for something a little more temp stable.

Did a bit more search and study. I shot a bit of 135 years ago, and it kind of dried up, pre internet.
VV135 looks pretty versatile across the board for 204/223 through 6BR. I didn’t see any negative on it like I do on 133.
What are you using N-135 in?

Benchrest buddy gave me some of his 135 “siftings” large kernels, yes he sifted it doing some testing. I used some in my 6BR and it is a bit slow compared to a partial jug.

.308 Winchester in M1-A's.

If you like 223, N540 also works well with the 80 ELD.

Already have my 75 ELD-M load so no need for a .223 load.

Does anyone have good experience with N560? How stable is it? How does it compare to RL23?

I use N540 in a heavy 28" 8 twist Bartlein, 223 wylde bolt gun with 75g ELDMs @ 3000fps and 1/4-1/2 MOA at 100 yards. Ran it out to 1K on steel and it does very well.

Velocity tops out at 3085fps in this particular combo with Lapua brass, but decided to back off down to 3K since we see triple digit summer's, and just be a little easier on the brass.

Ringo,

Small sample in one rifle, but...

My 257 Roberts Ackley really likes N560 with 100 Ballistic Tips at about 55gr @3300fps. Absolute Max in my rifle. 80*

I got it as a RL26 replacement & haven't yet tried it everywhere that RL26 shines, but it comes close in the 257 Roberts Ackley. With 100gr Sierra Spt, 55gr of RL26 beat it by about 60fps with larger groups while getting very close to max pressure. 60*

In the same rifle with 100gr Sierras again, RL23 pressured out at 53.5 to 54gr @3280 to 3320fps with pretty small groups. 65*

Both N140 & 150 have been stellar in a 22-250 with 52 Bergers.

560 is Not temp stable.
It is a good powder and competes with 22 ,23.
How stable, I use it in the N.E. and never had a issue. Get above 85* down S. You may not run it near max pressure.
