I had a 6.5 gr (30-30 improved) that performed on par with the 6.5 jdj, i.e. 120's @ 2400 fps from 14" barrel. I was able to get that performance with Varget, RL 15 and H-4350. Ended up selling it before using it to take game, but it was a hummer grouping 1/2" at 100 yds with preferred loads under a 120 gr balistic tip.
