I've been using 51.0gr of RL-19 with 140gr in my 7-08AI. It will handle a little hotter load in my rifle, but this load has been very accurate with the Partitions I hunt with. My rifle isn't as light as yours. Mine is based on a Sako591M action with a 22" #2 Shilen, 11 twist barrel. It sits in a pillar bedded McMillan with a Leupold Vari-X III 2.5-8 scope. Loaded with 5 in the magazine and one in the chamber, it weighs exactly 8 pounds. This rifle also shoots 50.0gr of H-380 very accurately. 49.5gr of IMR 4350 or IMR4831 is also very accurate, but velocity falls off. I've got a lot of loads ready to shoot with moly caoted bullets, but haven't had a chance to get to the range with them yet. My rifle doesn't like 100gr Sierra's all that well, so I'm trying the new Speer 110gr MHP moly. Since I'll be running moly in the bore, I've got a lot of 139-140gr bullets moly coated, as well. I'll let you know how they shoot. I just got my new Oehler 35P, so we'll see.
