At the time your gun was built, the "standard" 20-gauge shell in North America was a 2 1/2 inch case carrying a maximum charge of 2 1/4 drams of bulk smokeless powder or 18 grains of dense smokeless powder such as Infallible or Ballistite pushing a 7/8 ounce payload, and lighter loads of 2 drams or 16-grains and 3/4 ounce were common. In the extra cost, extra length shells of 2 3/4, 2 7/8, and 3-inch one could get 2 1/2 drams of bulk smokeless powder or 20-grains of Ballistite or Infallible pushing that 7/8 ounce of shot a bit faster.
  The high velocity progressive burning powder 1 ounce 20-gauge loads were introduced by Western Cartridge Co. as their Super-X in 1922 in their 2 3/4 inch FIELD shell. |

I am reading between the lines so I assume that modern low brass skeet shells are probably to hot for the gun if it is chambered for 2 3/4. I do not reload.

No, they're not too hot. Winchester AA will be fine IF the chambers do turn out to be 2 3/4". If they're 2 1/2", as made, Use RST loads. They're a little more expensive, but it doesn't matter, you're not going to be shooting league skeet with it.

In one of Sherman Bells "Finding Out For Myself" articles published in Double Gun Journal he found that shooting shells longer than the chamber increased pressure by about 300 PSI. That is a negligible amount. I shoot shells that are 2 3/4" in 130+ year old Parkers with Twist Steel barrels without incident, however I shoot modest velocities (1,150 fps) and light loads i.e. 10 gauge 1 1/8 oz of shot, 12- 1 oz, 16- 7/8, 20- 3/4 oz. I do not hesitate to go up an 1/8 oz occasionally, but don't do it when I shoot 100+ rounds a day.
