RE: .410 performance?
STRUTH A 410!!!!!!!!!!!!!!!!!!!!!!!!!!!mmm Id go4 da 12 gauge.In therory you can get more positive kills with a 410 due to the long string of shot!!however because ur shot is in a long line and not in a cloud it is much easyer to miss or clip n injure a bird. Ducks being very strong birds are easily injured opposed to droped.
MATE GET THE 12Bore
(it'll work out cheaper on rounds!!)
