I tested the sierra match king .375-350 grain bullets shot thru one-one gallon milk jug then wet news print, stock, annealed and drilled out to .052 hollow points and annealed. All the bullets except the drilled and annealed one tumbled and broke in two pieces. The one that was only annealed had stretch lines in the nose section like it started to expand. The drilled and annealed one's both penetrated very far and expanded all the way down to the taper of the boat tail with a very long cavity. The muzzle velocity was 2830 fps and the distance was 25 yards.
