Doesn't really matter if the cartridge is old technology. It killed deer just fine 100 years ago and the deer haven't been redesigned so it will do just as well today. Hunters are a different story. Many of them have allowed themselves to devolve into physically challenged stump sitters who don't know the animals or the woods and can't stalk well enough to get close for a shot unless it is over a corn feeder in a high fenced area. Eventually they will blend in with the other fungus on the stump and leave hunting to those who work on learning how. Meanwhile they keep trying to resolve their handicap by employing ever increasing numbers of technological crutches. Sad indeed - akin to playing golf from a cart with a mechanical device to swing the club for you.
