Depends if you want a kick in the shoulder that is not too bad. 12 gauge mossberg pump with modified choke will knock them out of sky. Mossberg 410 pump less kick and will still knock them out of sky. I start with the 12 gauge and if they are flying really good I switch to my 410 for fun and less kick. Hot temperatures on opening day make you want to carry the lighter 410. Pouch of shells weigh less too. IMHO
