Hey Mike.. sorry you're having trouble w/ the LRX. I just got a 300 RUM last fall so been doing some load development for elk season. It's a stock rem 700 (XCR II); only upgrade is a B&C medalist stock. Anyways, I started with the 180 gr. TTSX; both velocity and accuracy looked promising from the start using Retumbo. Shortly after, Barnes came out w/ the 175 gr. LRX with better BC numbers, so I started development for that (I'm a Barnes guy). Long story short, the 175 gr. LRX's shoot 1/2" group @ 100 yds. Velocity was an honest 3400 fps w/ a 3 -shot E.S. of 4 fps (again, using Retumbo). Needless to say, I was blown away.
I dont have any data in front of me, but if you're interested in either of the two (180's or 175's) I'd be happy to share. The combination of RUM case capacity and Barnes bullets can make troubleshooting very $$$.
