Any new info on N565 replacing RL26?

Hmrhead said:

I know this has been kicked around a bit in the past, but now that more time has past with RL26 being basically unavailable, has anyone got any new info on VV N565 as a replacement? Are you finding that it "pressures out" before reaching the RL26 velocities?

I have loaded for numerous 6.5SS and 6.5SAUMs.
N565 has never quite achieved RL26 velocities, usually 40-50fps slower with bullets in the 130 to 156 range. But N565 is more temp stable above 84°F.

N565 vs N560: N560 gets a bit more speed in lighter than 140gr bullets. But is less temp stable. N565 shines on bullet weight over 140+. More temp stable, too.

N565 vs H1000: Similar results to the N560 vs N565 data. But...H1000 is super stable, super clean burning, and cooler burning than N565.

N565 vs RL23: RL23 will outrun N565 with 140 or lighter bullets. 140+, the N565 catches the RL23 velocity with less pressure.

N565 vs Retumbo: N565 has seemed to beat Retumbo velocities in all bullet weights. Retumbo works better in larger case capacity cartridges, though.

On a relative side note to those interested .
I have three rifles I chambered in 6.5 Saum with .100 freebore .
Below is some data on one of the hunting rigs with powders of close burn rate .
4 round groups .

N565 did yield about 50 fps more velocity than N 165 before I reached pressure . I can't speak to Reloder 26 . I have limited data on N565 with the Saum but I am running it in 6.5 -284 with 140 s . Does well in it ..



6.5 Saum
Proof 26 inch 8 twist
.100 freebore

300 meters 80-87 degrees

140 Eld .025 into lands
N565 - 56.5 grs - 3041 Avg - 1.4 inches

Reloder 23 - 54.9 grs - 3048 Avg - 667 inches

H4831 SC - 54.5 grs - 3052 Avg - 1.9 inches

Reloder 25 - 58 grs - 3040 Avg - 1.7 inches

H1000- 57 grs - 3047 Avg - 1.97 inches

N-165 - 56.6 grs - 3046 Avg - 1.25 inches

153.5 Berger Hybrid .025 into lands
H1000 - 55 grs - 2916 Avg 1.63 inches

N - 165 - 53 2 grs - 2928 Avg - ..940 inches

I use N165 exclusively on my 30 inch tube for long range prone high power competition with 153.5 .

H1000 is a recent addition to the 26 inch proof and 26 inch krieger barrels and seems to lay down well around 2920 fps .and 2960 fps as does the N165 with 153.5 .

Fyi

I use a lot of the VV. 560-565-568-and 570 in big heavy bullet loads the burn rate on the h1000 is 3630, the retumbos 3710, RL26 is 3905 , vvn570 is 3950 vv560 is 4020 vvn550 is 4060 n530 & 540 is 4100 so if you can stay in around the same burn rate that mite help you out that should be burn temp not burn rate

Thank You Tommy T. I didn't see a burn temp for N565 in your post. Did you happen to have one?

Perfect! Thank You!

of course all of this would be moot point if anyone happens to know where I can get more RL26
