Nope. Cup and core for this cowboy. I shoot a 270 and load 140gr Hornady BTSP. Have used this combo for yrs and never had a bullet failure or lost an animal. Deer do not require a premium bullet to kill. They are fine boned. Up here in the great white north we have mature bucks that go 350 lbs, which are the ones I target for the better part of 3 weeks every fall, and have never had a problem with penetration.
