I just returned from 2 weeks in the Czech Republic and in Bavaria. I was fortunate enough to go on four driven hunts on four seperate days. The prevelant firearm was the O/U 12 ga/ rifle. Mostly the caliber of the rifle was 7x57R or 7x65R. Their were quite a few 9.3x72R in CZ. Also one Kalishnikov in CZ.

The animals shot were mostly Boars with 'any Deer' being the case on one Drive. (that was fun)
