Oscar;
One would normally assume the term "standard 2 3/4" shells" to mean factory SAAMI spec loads, for which this gun should "NOT" be considered OK. I assume here you are really meaning the standard 2 3/4" hull length as loaded with low pressure reloads. This is a totally different thing. I do not believe the 2 9/16" (65mm) was ever a standard 12ga (It was standard in 16ga) length in the US. Much more common was the 2 5/8" (67mm) length. Also 2 3/4" lengths were readily available much earlier than many seem to be aware of, so it is not correct to automatically assume a gun having 2 3/4" chambers has been re-chambered. There may simply be no way to prove it either way. Often about the only thing one can do is just to insure there is ample wall thickness at the end of the chambers.
