Chamber length question

Post by gator6 »

Is there any way to find out what the factory chamber length is on a Fox based on the serial number?

Probably not. A very few production cards mention chamber length and even at that if the card does say "chamber for 2 3/4" shells" that would be a 2 5/8-inch chamber.

I've posted this several times.

FOX CHAMBERS --

The only two A.H. Fox Gun Co. catalogues, that I have seen, that state chamber lengths are the 1913 and 1914. They both state 12-gauge guns are regularly chambered for 2 3/4-inch shells, 16-gauge 2 9/16–inch shells and 20-gauge 2 1/2-inch shells. That being said, virtually every 12-gauge Ansley H. Fox gun made in Philadelphia (other than the HE-Grade Super-Fox) that I've run a chamber gauge in shows about 2 5/8-inch. The chambers of unmolested 16-gauge guns seem to run about 2 7/16-inch and 20-gauge guns a hair over 2 3/8-inch. A very few graded guns were ordered with longer chambers. Savage began stating chambered for 2 ¾- inch shells in their 1938 Fox catalogues.

All this being said there is a good body of evidence that back in those days chambers were held about 1/8-inch shorter than the shells for which they were intended. In the book The Parker Story the Remington vintage specification sheets on pages 164 to 169 call for a chamber 1/8-inch shorter than the shell for which it is intended. Also, in the 1930's there were a couple of articles in The American Rifleman (July 1936 and March 1938) on the virtue of short chambers. A series by Sherman Bell in The Double Gun Journal showed no significant increase in pressure from shooting shells in slightly short chambers. IMHO I don't much sweat that 1/8-inch in 12-gauge guns. On the other hand when one gets a 20-gauge chambered at 2 3/8-inch likely intended for 2 1/2-inch shells I do worry about folks firing 2 3/4-inch shells in such guns.
