I've generally seen a 200+ fps increase from .38 Special +P to .357 Magnum in my testing of various bullet weights and loads in my 2 1/4" SP101. While my standard +P .38 158 grain is a max load according to the books (and running 825-850 fps) out of a snubbie, magnum loads nowhere near max easily make 1050fps, and could be pushed much faster with available data.
I don't have any experience with Buffalo Bore ammunition, and at the prices they want for it I probably never will, but I have heard from a number of sources that their 158 grain load really does make 1000 fps out of a snubbie. I am sure I could make the same with a .38 Special handload, but I'd be going out beyond the data available. On the other hand, exceeding 1000 fps with a .357 Magnum load in a snubbie is not only possible, its easy.
I often hear that short barrels destroy the benefit of using magnum ammunition over .38 Special ammunition, but my own testing of bullet weights from 110 to 200 grains in both .38 Special and .357 Magnum has always showed a significant increase in velocity out of the snubbie SP101 when using Magnum ammunition instead of Special ammunition. Usually its at least 200 fps, which is nothing to sneeze at.
Recoil is subjective, so its hard to quantify, but while magnum ammunition does recoil more than special ammunition, I have not found the difference to be controllable vs. uncontrollable.
