10 ga for fowling

[C. Aaron Beck]

So I joined the forum in order to tap into the wealth of information on using older guns to hunt with. Currently dont own a parker but am looking for a 10 ga to use for geese. I thought I had a line on a steel barrell Ithaca but it turned out to be too worn for shooting. Thus the search continues. Most 10 ga for sale seem to be parkers and almost all are damascus. Would you gentlemen please indulge me with a discourse on the possibilities of shooting waterfowl with damascus guns? I am aware of the rst loads (I even bought a case as I was eager to put the cart before the horse with the Ithaca) and periferally aware of the possibilities of handloading nice shot, bismuth, itx and the like. how does one determine which gunsmith is qualified to approve a certain gun? how does that gunsmith tell if the gun is safe and if so with what qualifications i.e 1 1/4 oz loads but not 1 1/2 oz loads etc..
You have a great internet forum here and I hope you will share some information.
