It is simply the best medium range deer round ever made. And, during the fall sales, you can get them for about $12 a box. People just have a tendency to ignore the obvious.
When I had my farm years ago, we generally shot deer at 150 yards. If a high lungshot was made, the corelokt routinely went all of the way through, leaving a silver dollar sized exist wound, gushing blood, and the deer only travelled about 50 yards. For shoulder shots, the round typically ended up flattened under the skin on the far side, in a perfect mushroom, and the deer travelled about 25 yards.
The most overhyped, overly expensive, useless .30-30 round being sold is probably the Federal "Fail Safe." What a crock!
