Here is the quick and dirty:
Ballistically its pretty much the same as the .300 WM. It uses a bit less powder so there is a bit less recoil (not as much as winchester would have you believe). It uses a beltless, short and fat cartidge, which gives it a good base to go off of for accuracy. Its probably a bit more consistent than is the .300 WM. BUT, (and the reason its not listed on SC), there is no match grade ammo for this cartidge, which pretty much takes it out of consideration for sniping/sharpshooting.
