Hi there,
I'm new in here. I just bought a model 50 yesterday. Its a 12 guage 30in full choke. I did a couple of rounds in the range. I'm using a #8 lead for now. Maybe in winter I might join the duck hunt. Can you guys advise me what brand,number shot and size number can I use.
The dealer that I got it from told me any material except steel coz it might banana peel my barrel. The only problem in CA is you can't hunt lead it has to be steel. You can also email at eugenefelisco@comcast.net
