So I'm sitting on 8lbs of N568 and wondering if anyone has given this a shot in a 7 saum or anything else for that matter. I would love to hear some results with anything you may have tried it in.

No matter what the numbers say it is not faster than 570, ive used enough of both to find out.N568 is a blend between N565 and
N570
It is closer in burn rate to N570 than N565.
I forget the exact number on N565 but it has a .33 to .34 burn rate.
N568 is slower at .30
N570 is slower still at .27
N568 anecdotally is more accurate than some other powders in its burn rate class but it does not produce the velocities some other powders can or do.
I like the way it meters best of all the N series VV powders.......maybe this accounts for lower ES and SD and better groups?
It meters more like H1000 or RL 26
Not chunky like N560, N565, N570.
Though its burn rate is between both N565 and N570, its velocities for a given bullet are below both N565 and N570.
Whats the difference?Burn rate or velocity???
Burn rate is faster.
Velocity is slower
The burn rate of a powder is the rate at which the powder itself burns and the characteristic way in which it generates a pressure curve from chamber to muzzle.Whats the difference?
RL25 | 0.384 | |
N560 | 0.371 | |
H1000 | 0.366 | |
Ramshot Mag | | 0.345 |
RL26 | 0.3397 | |
Acc Magpro | | 0.3342 |
Retumbo | 0.337 | |
N565 | 0.3109 | |
IMR8133 | 0.3 | |
N568 | 0.3 | |
Ramshot LRT | | 0.285 |
N570 | 0.277 | |
RL33 | 0.267 |
I dont think you read what I said.You can throw all the numbers from quickload all you want i will go off real world experience. I remember how quickload was way off when the Nosler cases first came out.
FACT! it takes more 568 to reach same velocity than 570 by atleast 2 grains in my 30-28 with everything being equal.
