Looking at a British .410 and came across the following proofs. 410 LC, 7/16 ounce load I assume. So is this a 2 1/2 chamber instead of the common early 2 410 guns I have seen? Load does not sound like it could be a 3 load for a 3 chamber at all. But the LC, which I understand stands for long chamber, with the 2 as a standard chamber, the 2 1/2 might have been considered the long chamber for a between the wars .410. If thats the case what were the proof/working pressures?

KYJon,
The proof marks are for 2 1/2 chambers.
Burrard gives the pressure generated by 2 1/2 cartridge on page 156 of his book, "The Modern Shotgun. Vol 2,The Cartridge."

Just be careful as 2 1/2" Remington and Winchester stuff is a bit too hot for the English 2 1/2" gun. Best to use the European made ammo. Lagopus..

The payload in the North American 2 1/2 inch .410-bore shell was 3/8 ounce from its introduction in 1914 until a year or two after the 1933 introduction of the 3-inch .410-bore shell. For Western Cartridge Co., the 2 1/2 inch Super-X shell still had 3/8 ounce of shot in the March 15, 1935, Price List and was up to 1/2 ounce by the December 24, 1936 Price List.
