Gotta agree on the 168gr TSX in the RUM. My go to load is clocking right at 3370fps out of my RUM and I pushed three of these thru a moose this fall. Penetration was very impressive, one went stem to stern on my bull. Talking over 5 feet of penetration, entrence in right ham, exit out front of chest on left side, Also placed one at a hard quarting angle thru the pounch and out the far shoulder right at the shoulder ball. actually pushed grass out of the exit wound. Range was about 180 yards.
I could push that bullet faster but have found excellent accuracy with this load, sub .5" groups with reasonably consistancy and always under an inch. 300 yard groups averaging around 1.5". Thats about as good as I can do with any rifle.
