Pressure increase with 2 3/4" shells ?
I know this has been discussed at great length - but what was the percent increase in pressure that Mr. Bell claimed when you shot 2 3/4" shells in the 2 5/8" Parker chambers ? Was it 10%, less ????
The reason for my asking is that I ordered up some NiceShot loads (in 2 3/4" 12 gauge). They are loaded with 1 1/8 oz. of shot, with a claimed velocity of 1250 fps. (That's what was written on the box, however Dan said it was actually 1200 fps, and the low-pressure loading of approx. 7900 - 8000 psig.)
So, my plan was to shoot these duck loads in my 1895 DH 12 gauge, which is in nice shape, #2 frame, with 2 5/8" chambers and seemingly un-honed 32" bores. If Mr. Bell's claim was a 13% increase in pressure, I see no reason to fear a 9,000 psig shell.
Is my logic flawed ?
