ITHACA SUPER 10 TO 3.5"?
 

Opinions wanted on taking an Ithaca Super 10 from 2 7/8" to 3 1/2."

I know the Supers are rarer than the 3 1/2" magnums, but it is what I want to use. Do you think Ithaca beefed up the guns when they went to extended chambers in 1932 (I believe that was the year)?

Thanks for the input.

Ithaca 10 GA 3 1/2" Magnums weigh in between 10 1/2 and 12 lbs. Compare that weight with your gun's. That's the level of beefing done.

According to Walt Snyder's book, they did beef up the gun for the magnums.

They are heavy and i would think you should not have too much trouble physically lengthening the chamber from a wall thickness standpoint.

The magnum tens had a through lug on the barrels which was supposed to have made the difference in it holding up to the heavier loads. The earlier Super tens did not.

I wouldnt.

Please please please:shock:


Do not modify a super ten.

If you want a 3 1/2 inch magnum NID there are several for sale on the various sites now


There are many who would give an unaltered ( chamber and chokes) Ithaca super ten a loving home and a chance to do what it was designed for

Ithaca Gun Co. warned against it at the time.

I wouldn't do it. Ithaca's NID Magnum-frame is longer, has a larger diameter hinge pin, and the barrel lug extends through the bottom of the frame.

Oh my. :clap:

Thank you Gentlemen for your replies. I truly did not know if they modified the frame from 1926 with the Supers to the 3 1/2 inchers.

That is what is so good about this site, ask a question and one get the information needed to make an informed decision.
