First, welcome, JustinL!

Second, down here a 20ga. 1100 in one or another of its several iterations may well be one of THE most popular dove & bird guns of recent times. That they mimic a model 12 in hand was no accident.

Me? Any one of several 20's will get some time afield and get the job done efficiently and effectively w/7/8's oz. of shot. Perhaps a 16 w/a similar load, primarily because old wood can suffer from undue recoil & more shot than that isn't really necessary. For those who swear by factory 20ga. 1oz. lead ammo, it was all much SLOWER than the 7/8's oz. loadings until very recently & much of it still is. Just saying. Enough thread drift, eh?

Dove are a lot like skeet; not difficult to break, but very easy to miss.

Hope the coming season is productive, fun and above all, safe for all here. Please consider taking someone young afield as well, if you have the ability to do so.
