Hello,

I have about 15 years of experience with the driven hunts.In most places you will rarely be able to let more than 3 shots on game.The big clip isn`t necessary.Through the years I hunted the boar with a o/u shotgun,a combination gun(again o/u 12/76+7x65r),a mauser m98 in 8x57is and a benelli montefeltro semi auto in 12 gauge.I've got some experience with 9.3x62,30-06,308 and 7x64 calibers also.Caliber wise everything from above 6.5mm caliber will do.You would do best if you avoid the magnums ,the shot distances rarely exceed 100-120 meters. Heavy round nose soft points are best as bullet selection goes.
As I'm not the best of shots I mostly try to hit the heart/lung region. A good practice on running game is to always aim for the head,there is a great chance that you would still hit a vital point(neck,vertebrate or the rib cage(lungs,heart region)) if you miss it.

Best regards,
Jordan.
