Just a side note - in SOME countries, they have minimum PG caliber requirements for forgein sport hunters that may not apply to local citizens. Some limit it to various species and some have a blanket caliber or muzzle energy minimum. Some PH's follow these limits, and some don't. GENERALLY, something 7mm and larger is just about universally the legal minimum for all PG species. If someone can shoot a 308 with 150gr or heavier TSX you'll never have a worry about min cal or min ME.
