Chamber depth

[Bruce Day]

Have you reviewed the Sherman Bell Double Gun Journal articles which determined that there was approximately a 3-5 percent increase in chamber pressure from shooting shells 1/4 “ longer than than chamber length?

Is your gun so infirm that this extra pressure is likely to bulge the chamber ? Do you intend to shoot SAAMI max pressure shells so that the extra pressure could harm the gun ?

You asked if moving to a shell with more shot would help you hit more quail . That would help you kill more quail but not hit more. A 28 ga is marginal in killing load anyway , and the long shot string does not help. Shoot some sporting clays and the pattern deficiencies become apparent.

My friends who come out here and hunt high plains quail in the wind , many of them bring a 28 ga but it goes back into the truck by noon. Plantation quail or released birds I think it would be well suited for that. These birds ran out and flushed at 25 to 30 yards so that the shots were 40 yards.

Now there's a loaded question.... no pun intended.

We can't 'know' the answer to that question without examination of wall thickness by an expert in the field - a qualified double-gun smith. And then it would be his opinion subject to conjecture.

IMO, unless it can be proven that the chambers were cut to 2 3/4" by the manufacturer it should not be shot with anything other than 2 1/2" shells loaded to manufacturer's specs at the time of production.

We need to be sensible in these matters.
