Chrono is brand new also.
Both of the listed powders are putting great groups down range at 100.
The gun is a Ruger m77 with a 24' pipe. I get about the same #'s out of my Winchester Mod 70.
Need more cowbell.... the 210 should eat a bit more powder than the 225. Unfortunately you are running out of case capacity and both Lyman and Barnes show that pill topping around 2800 fps in a 24" bbl. with most powders including rl19 and i4831. Run your charge up a couple of grains on rl19 and see where it goes if you still have headroom.
I'd think about going to rl17 or 4350 here if rl19 won't wake up. You need a bit snappier/faster powder for these two rifles it seems to me.
