I was surprised to see the groups with Crosman domed from my P35 in 22. It is tuned to shoot H&N Baracuda Match 21.3s. So the 14.3 grain Crosmans averaged a little over 950 fps. But the groups were 1/2-5/8 at 33 yards. The H&N will go into 1/4 inch groups at that distance but the Crosmans are plenty good enough for plinking or even short range hunting. I use them in my Prod when I cannot find the copper plated H&N FTTs it likes a little better. I've dropped about half a dozen squirrels with them. Work fine as long as they go into the front half of the body. HPs shoot about the same from my Prod, haven't tried them in the P35.
So based upon that, I tried 10.5 Crosmans in my P35-177. It is tuned to shoot H&N Barracuda Match 10.65s in 4.50 head size. It shoots H&N Baracuda Power almost as well. Crosmans shoot at the same velocity as the H&Ns but the groups open up to about the same size as the 22s. Quite useful except for target shooting.
