Saddlesore, this is probably not kosher feedback. I've lengthened the forcing cones on a number of guns and have no complaints. Then, some years ago, I just got lazy and quit having the barrels altered. I shoot 2 3/4" hulls in the short chambers all the time and have never experienced any problems whatsoever. Nor did any of the oldtime gun experts, such as Gough Thomas, Burrard or Askins or any number of the old men. In fact, Parker even recommended shooting the longer hulls in their short chambered guns, feeling it provided a better gas seal. Now, I want to be perfectly clear on this: I would never shoot longer SAMI loads in a short chambered gun EVER! All of my loads produce pressures in the area of 7,000 psi or less--always! Fairly extensive testing of shooting longer shells in short chambered and short forcing cones was conducted some years ago by Sherman Bell and results were published in the Double Gun Journal. The conclusion was pressures did not increase substantially, certainly not enough to cause any concern.
