If I had a weight for the Ruger I could tell you with more precise figures. But if you use the same load for both guns and if the weight of the Ruger is 1/2 that of the Encore,,,, the Encore will have slightly half of the recoil velocity and energy.
But let's say the Encore is 4.5# and the Ruger is 2.5#, and again with the same load,( i just plugged a theoretical load in from a manual). The Encore had 14.5 fps velocity, 14.7 ft/lbs energy, the Ruger was 26.1 and 26.4 respectively.
Personally, I think the grip and how it fits the hand has more to do how recoil is felt and perceived. I had a Ruger BH some time back, while not brutal, I didn't find it a pleasure to shoot. My Encore with a .30 cal running a 165 gr at 2500fps, falls between those 44 numbers above. with the factory syn. grip, I found it less than pleasant and was using a semi 2 handed grip. I switched to a wood grip that I custom made to fit my hand. That same 165 gr load turned into a breeze to shoot and my groups were cut in 1/2. But a Pachy would have made a difference on the BH also. Grip angle on traditional revolvers are made for "natural pointing", little thought in design, goes into recoil management.
I know this got slightly off and more in depth then what was asked, but felt it was relevant, when comparing.
