I'm looking for data, experience with this powder.
I worked up a load for my 26 Nosler, 139 gr. Scenar over 79 gr. n-570, 3,320 fps, half inch groups at a hunderd. Burn rate is about right for this round. Vv powder, although expensive, is top notch.
I don't see much data on n-570, none for the Nos., mostly .338 Lapua, etc. I calculated my load based on comparables.
I checked with Pat (Scenarshooter) about the 139 gr. Scenar at 3,300+ fps. He's used it in his 6.5 SAUM's at 3,200 fps and said it should work well.
He mentioned a 135 gr. JLK bullet with .630 G1 B.C., said it worked well. I didn't get details on terminal performance, but it's probably good if Pat said it was good. And, I'm sure he takes terminal performance into consideration.
Any assistance with n-570 will be appreciated.
