Re: 7mm RUM velocity
I'm shooting a 26" SF Sendero in 7 Ultra and am getting 3500+ with a 140gr NBT Moly over 96.0gr of I-7828 lit by F-215s. I don't think this is max, but it shoots so well, I'm going to leave it alone. I haven't done much with the heavies because I haven't been able to find the really slow powders, i.e. H50BMG and the like.
As usual, I would recommend you reduce any load and sneek up on max. My understanding from other shooters is this round spikes pressure fast.
