Some time ago I bought a very light Irish 12 bore (Hunter and Sons). It seemed to kick a lot. I had Scott Carlson lengthen the cones. When I got it back, it seemed to kick a lot.The only immediate difference I noted was that my bank balance was a bit lighter.I now follow Mr. Woods advice. I habitually shoot 2 3/4" LOW PRESSURE loads in short chambers...Or, Short RST's
