The North Fork is essentially a monolithic, similar to the TSX but with a tiny dab of lead in the hollow-point to help it expand.
Also recently mentioned elsewhere on the Campfire that have seen a 150 Partition from a .270 Winchester penetrate close to four feet through a moose on a quartering-away shot, from the left ribs into the right shoulder.
I almost did take a 270 with 150 Core-Lokt moose hunting. Instead I opted for a 7mm Rem Mag with 175 Federals
