No one can answer that without examining the gun. Armory steel would have been almost certainly intended for smokeless powder, but what has happened to the gun in the last 80-100 years could make it unsafe now. Also, depending on just how old it is, the chambers may be only 2 1/2". Have a competent gunsmith check it out.
Get your brother in law to shoot it for you.
yes your Stevens shotgun should be safe to shoot,I'm not saying run nitro mags in it but it should function fine with high brass game loads.....they are a well built shotgun designed by John Browning..if your ever looking to sell it i'd be interested..........email@example.com
Your best bet would be to take it to a gunsmith for a professional appraisal.
Have it examined by a gunsmith.
In a word, no. In two words, absolutely not. www.countrygunsmith.net
So, the answer is you to stupid cause is crazy
The barrel should be stamped with the applicable shells that can be shot through the gun. i.e.-( chambered for 2 3/4" and 3" loads)
what is the factory combination for my safe ?
if it's an "ithaca mag-10", it was introduced in 1977 and discontinued in 1986, the answer to your question is yes it is safe to shoot steel loads, however you may want to have the choke measured at the muzzle by you local gunsmith.too much constriction could result in a barrel ring and a more open choke should give you a better pattern with larger sizes of steel shot i.e. t and bbb. pbl
safer to take it to a gunsmith. parts may be missing or gun may not be safe to shoot.
Yes. Slugs can be fired in any modern shotgun. It is best to use an improved cylinder barrel. Modified and full chokes are usually not as accurate, and too many slugs can cause them to pattern poorly with shot loads, although it is perfectly safe to use them.
