.357 and .30 carbine are easy to compare with reloading data since they both perform best with the same powder. (H110)
Hogdon's published website reloading data shows
.357 110gr from a pistol at 2078fps
.357 110gr from a carbine at 2398fps
.30 C 110gr from a carbine at 2106 fps
The Hogdon data does not mention test barrel length, but seems to re-enforce my own data claims.
Ruger used to make a .30 carbine SA revolver. I have load data for them as well. .30 with 110gr at 1590fps.
