If that was my rifle, I'd try some Hornady factory ammo to see how well that works.
Sucks to spend that kind of $$ and not have it working reliably right out of the box.
You wouldn't worry about the extraction issues huh?????
. I know, the op said it wasn't ejecting right, but if a fired cartridge just lays on the follower after pulling it out half way and doesn't eject, it sounds more like a bad extractor from the op's description of what's happening...
