If you're interested, QuickLoad predicts that 66.8gr Rl-25 would give approximately 2,950 fps (7mm-08 velocity) with a 95% case fill.
Otherwise, I'd try those loads I mentioned, just be aware than 80% case fill might be position sensitive. I don't know about that powder in particular. You'd have to try it by tipping one all the way forward and then carefully bringing it level to shoot so the powder is away from the primer and then another aiming up and bringing it level so the powder is against the flashhole. A chrony would be helpful but any accuracy difference might be telling too.
