You can link it to pressure or velocity because they are intrinsically linked and cannot be separated. An easy way to calculate recoil velocity is conservation of momentum wherein you figure the mass and velocity of the ejecta and divide by the mass of the gun. Momentum can also be converted to impulse which is force*time. While force won't remain constant due to the pressure curve, dividing by dwell time in the barrel will give you an estimate. Pressure times area will also give you an idea of the forces but you also need to estimate the friction force of thr barrel on the bullet which is offering a mild containment effect. It is all linked, the math just goes in circles. It is like folks trying to attribute effects to energy vs momentum, can't have one without the other.

Very true guys; but my point is that pressure is internal, and velocity is external. Maybe being a stickler here, but it is entirely possible to overpressure a gun and get less velocity than with a slower burning powder at lower peak pressure. And the lower pressure load at higher velocity will recoil more.

Agreed. We tend to focus on peak pressure as opposed to the entire pressure curve. I think most of us understand that a big magnum with a full load of 296 has more recoil and a higher velocity than a full load of Bullseye with the same max pressure PEAK.
Pressure is probably one of the most misunderstood and misapplied properties in gun conversation. It's especially common in the big bore relolver world where a few writers kept throwing it out there, often without making very valid or thought-out points, and people continue to repeat these points, often with even less grasp of the subject matter than their ill-informed source.

Nowhere is that more evident than the .44Mag vs. .45Colt argument.

The up close and personal itch is scratched with a bow, because it's the only option you have during archery season. To go out and hunt big game with a handgun as your primary weapon during a general firearms season is a choice. Odds are you could also hunt with your bow during the general season but choose not to. The reason is probably the same as why you do not use a handgun as a primary weapon. The fear of the animal of a lifetime being outta range. To handgun hunters, that is not a fear, but the whole challenge. This is what non-handgun hunters never understand....this is why they would rather carry a rifle than "a SRH or SBH size revolver" or an X-Frame. It has nuttin to do with the size and weight of the revolver, but all about the simplicity and ease of shooting something with a rifle as opposed to a handgun.
BTW...I bowhunt deer also. Until old age caught up to me and my shoulder gave out, I gave up compounds and used a recurve the last few years, for the same reason I use a handgun. Now I have no other option, I have to use a crossbow or stay home. I'd still rather use the recurve.

You also choose your hunting locations to suit the handgun with more limited shooting distances. So, in the example of the buck of a life time, you might not even know that buck is even there or was ever there. It is not something that bothers me particularly. Don't really care about "bucks of a lifetime" any more, just a nice buck.
