Will Evans posted the result of shooting 2 3/4" loads in his 2 5/8" chambered (assumed to have been accurately measured) Parker. Maybe it was only a bad batch of plastic?



Less impressive is a "feathered" case mouth; 67mm on left



All these shells were 2 11/16", which I would use if there was evidence of a longer hull entering the forcing cone. Sherman Bell did not test 2 3/4" shells in 2 5/8" chambers so we have no pressure data however.
