Re: What length barrel for rabbits?
Not sayin you need to go to an O/U. The pump and auto that the OP is using are great guns. I wouldn't carry a $2400 gun for rabbits either. There's no need to spend half that much. I hunt grouse, pheasant, rabbits, waterfowl, and crows all with the same gun and the O/U is just my personal favorite. Bought my SKB model 500 12 ga. imported by Ithaca in the 70's for $350. Great O/U that you still can buy used for $600-$800. Bought a model 600 2 years ago for $550. There are some great bargains in used O/U's if you look.
The older I get, the stronger gravity becomes.
