I hope both of you are joking when you claim to be able to tell the difference on recoil between a load that weighs 500 grains, including shot, wad, and powder and a load that weighs 509 grains, especially when a good part of the extra nine grains of powder are in gasseous form on ejection. You guys are both victims of the "Old wive's tales of reloading". Jim's original statement was obviously meant to imply that a heavy load of powder in a published load would recoil noticably more than a lighter load of powder in a load of the same shot weight and velocity. It is plain not true and is "An old wive's tale". I personally think he was joshing, I hope Mike was aware of the joke. I'm not sure. Remember Mike, Jim said he could "feel the difference". I am amused.
