Fine powder for 7mm RM?

[Jimmy76]

Hello everyone

Short question: I have used Vihtavuori N165 in my 7mm RM. It is very good one, but i never have tested any other powders. There´s still need for advice, tuning that load for better accuracy, so does anyone has tips?

Barrel is Border 26" 1:9 twist, load has been Sierra MK 168gr, VV 65.0 grains, Federal Gold medal primer, Norma case.

Retumbo works good, RL25 or 22 also, had luck with 162 amax in all of the above. Of course the close to the lands the better.

Any of your slower powders will work well. H1000, Retumbo, R25 would be top picks for the heavy bullets in 7RM. H4831, R22 would also be good.

Retumbo seems to be intresting one. Vihtavuori has Powder - N560, which has some extra kick from NGL. Anyway, N500 - series FPS amount aren´t so equal...
