Just returned from Wy. deer hunt. We took one buck that had been crippled at 587 yards. He took his last look back and it was his undoing. One round from 6mm-284 with 85 grain Nosler solid base through both lungs. Buck down like hit by a .50. Bullet exited and caused LOTS of internal damage. This was my 1st animal with this round and I am very impressed with it.
