Great article with some interesting data
But let’s take a closer look at the 125 gr 2 1/2” data again, this time with recoil calculated for a 36oz 2 1/2” Model 66:
10 grains Unique, 125 gr at 1,227 FPS
Recoil impulse; 0.9 pound.sec
Recoil velocity; 12.91 FPS
Recoil energy; 5.83 ft lbs
20 grains Win 296, 125 gr at 1,286 FPS
Recoil impulse; 1.16 pound.sec (29% more)
Recoil velocity; 16.56 FPS (28% more)
Recoil energy; 9.58 ft lbs (64% more)
^^This right here is why I don't shoot H110 from my model 66 2 3/4" with any bullet. My palm is telling me the same thing as the data. The recoil makes it less enjoyable, and in my hands, less accurate. Put that same load in my Henry 20" and it's a joy to shoot, and extremely accurate.
I've always wanted to try Universal because as mentioned, it is so close to Unique in burn rate, but meters so well and isn't as dirty. But who can find it these days? It would be interesting to compare to Unique with this type of testing in different length barrels.
