N560 and 7mm SAUM

[Dubbo]

Any good experiences with N560 and the 7mm SAUM with 162-168 grain bullets? How is the temperature sensitivity of the powder when compared to a powder like H4831SC?

QL shows it to be a good fit.

Thanks for the data. I have only tried H4831SC but am looking at other options.
Also thought about H1000 but it may be too slow, the tube is 25", I can seat bullets about 0.050" longer than factory but with Norma brass a compressed would be no more than 64 grains. H4350 may be another option?

I'm happy with N560 and H162s up to B180 vlds. H4350 is another good selection for lighter weight sub 170gr bullets. My favorite was win780 supreme; N560 is my next best substitute. H4831SC is performing well too. I didn't have luck with h1000; accuracy good, but not velocity. Might be good for longer barrel life?

What is your barrel length, how stable has the velocity been on the N560 when temperature changes?
