No need for monometal bullets here. I just busted my umpteenth buck with my .243 last weekend. One shot from a 100 gr. cup/core {Federal "blue box" factory} was all it took. Smashed the onside shoulder to smithereens, traversed the chest cavity diagonally and left a nickel sized exit on the far side. Range was 50 yds. and he dropped so hard I had to pry his pecker out of the ground with a shovel.
