Quick load shows n-570 as the top powder for velocity in the 26 Nosler. I wonder why Nosler hasn't included it in their data.

It's a double based coarse stick powder that won't meter. It just stacks up.

I remove the RCBS Uniflow drop tube, dump powder in a scale pan, tweak load on the scale.

Double base with extra Nitro makes it a high energy powder. It may burn hotter, cook barrels faster. Just guessing. So far, I'm liking what I see, great velocity and accuracy.
