Perceived recoil is just that - perceived by the shooter. We can calculate the actual recoil with the gun weight and ammunition specs, and the numbers will show the heavier gun will have less recoil with a given load. That doesn't mean the shooter's perception matches the calculated numbers since other factors, such as how each is gripped come into play. If one gun gives higher velocity with the load, that will up the actual recoil.

Lots and lots of variables when we speak of felt recoil versus physics defined recoil.

With the gun weights given by borderboss above, with identical ammunition, the recoil values work out to;

39.7oz gun gives 5.50 ft-lbs

38.6oz gun gives 5.66 ft-lbs

I used 800 fps with 5.0gr of powder and a 230gr bullet for the ammunition
