N565 Temp Testing.

[Rhovee]

I have been loading with N565 in my 338 NMI. The burn rate falls right on top of H1000. Same charge gives me the same speed. The load has been extremely consistent. I loaded three rounds and put them in the freeze in a small cooler. I used CCI 250's and Peterson brass annealed every firing. 26" Krieger

78 Degrees. 2758-2755-2752

34 Degrees. 2749-2751-2755


It's a very stable powder for these testing conditions. Ammo was shot in the evening at 65 degrees. I shot one round to dirty barrel. One minute between shots with chamber cooler fan.

This is GREAT news because I am really liking this powder and have been recommending it to clients. Thanks for the report!

I'm happy to hear it as well seeing as how i bought 8 pounds for one of Rich's wildcats. Tried it in another one of his wildcats I have, a 270 Sherman, and it's pretty close to RL-26 in it. I think I pressured out around 20-30 fps slower with 565. Haven't shot enough of it yet to add anything to your temp tests though. Planning on using it in a 25sst that should be done soon.

I think when you shoot it some more you will find its very close to H1000 burn rate but more energy!

I like h-1000. Not always the fastest but it will work in most of the things I like to shoot so that's good news.

you'll get more velocity and still have stability!

I have 46 pounds of H1000. It's my go to in every gun. Some random barrels don't like it. It was nice to find an alternative.

Thanks Ryan. I have found N570 to maintain POI through many different temps but never any formal testing.
