It would have been great to have someone with expertise like Bill’s on this thread. As we get older, we lose more of our friends. It never abates and I hate it. I miss all of my friends who have passed. I also miss the many bird dogs and retrievers I have had over the years. I remember them all and think of them often. I especially miss my two all-time best grouse dogs, Rusty and Stoney. They were both grand gun dogs and real characters.
Heaven for me would be a Tinkhamtown type experience with both Rusty and Stoney leading the way. Rusty was my first bird dog and Stoney came much later. Hardly a day goes by that I don’t think of them and the others. I was blessed for sure. |

I quoted from a 2004 Accurate Reloaders Guide about pressure does not effect recoil. Here it is:" Recoil: This is certainly the most discussed aspect of the shotgun shooting sport, and this is understandable so, because it determines the " comfort " of shooting hundreds of rounds in quick succession. Because it's such a subjective issues/subject, the conclusions and recommendations are most of the time unfortunately shrouded in confusion, and corrupted by improper comparisons.
Normal physics still do apply, and in this case Newton's Third Law: For every action there is a equal and opposite reaction. Formula: Mass of bullet+ mass of powder X velocity = mass-gun X velocity-gun. " I don't see pressure anywhere in the formula. They go to write about the shooter, because he's holding the gun, becomes part of the equation. This is where felt recoil comes into play. So, I'm not just giving my opinion, but quoting what a powder company has written in a reloading manual. Hope this clears a thing or two up.

This one of the best and easiest to use recoil calculators I have found. Additionally, it does a fair job of explaining free recoil calculations.
http://www.omahamarian.org/trap/shotshellenergy.html You can easily play around with different parameters to see the effect they have on free recoil. You will quickly see that shot charge, velocity, and gun weight are the parameters that have the most effect with shot charge being the most significant. You will also see that chamber pressure has no bearing on any of the calculations. |

Physics aside I vote for Shot charge and Gun weight making the significant difference with recoil. Reason is range of variables are much larger than powder charge. With a 12 G You can shoot a 6 lb or 9 lb gun. Load can vary from 3/4 to 1 1/4 oz. Powder charge minor differences.
