I'm not a shotgunner at all and haven't hunted birds in decades and need some of your expertise.

My son just got an offer to go pheasant hunting next weekend and after the excitement wore off I remembered the steel shot and old guns issue. I have two 50's - 70's era shotguns that he'd have to use. Believe me, I 'd love to use this excuse to buy a new Citori or even a new pump, but money is insanely tight right now so we have to make due with what we have.

One gun is a Sears Ted Williams 20g pump with the external adjustable choke which I believe is the same as a Winchester 1200. The other gun is a 50's or 60's vintage 16gauge pump Winnie. that's all I know about it at the mement, I'll check it out closer tonight.
So, if we shoot either, is it dangerous to shoot with steel shot? This is not worth somebody getting hurt.

Also, if I replaced the barrels with new barrels would these guns be good to go from here on out? I'm thinking that's the best bang for the buck if I can find replacement barrels reasonably priced.
Both guns are in at least very good shape, with that Ted Williams probably have less than 50 rounds through it.

Thanks!
