Absolutely!

Please know that there are a lot of rechambered 10 gauge magnums out there which may have lost their collector value. Are they safe? One can measure the barrel wall thickness at the thinnest point of that extra chamber length, find the tensile strength for that grade of steel, and calculate that for the hoop strength of a thin wall pressure vessel.

For a fluid steel #3 frame Parker, most rechambered guns are probably safe. Have a good gunsmith and mathematician check and calculate this for you!

For a Damsacus Steel barrel with longer magnum chambers and lower tensile strength, it may very well not be safe!

Oh, the SAAMI maximum mean working pressure for a short or magnum 10 is 11,000. I would want my barrels to be good for factory proof loads of around 19,000 psi or higher!

The above stated, a heavy load in a short 10 will cream a turkey or goose!

Be safe out there,
Mark
