Hunting With Cowboy Loads?

[Larryjk]

Are the "cowboy loads" fast enough to meet the state requirements for energy? A .357 is marginal for deer but still travels faster than a 30-30 at 1100 fps with a 170 grain bullet. Most of the "cowboy" loads today are all for short range rapid fire with fast recovery for followup shots, not for careful placed shots at normal velocity for that caliber.
