"...they aren't really all that fast, often coming in at 11-1200 fps...".
Factory Federal 100gr JSP averages 1600fps from my 4 5/8" Single Seven.
1550fps from the 7 1/2" Single Seven (b/c gap, I believe). 2241fps from the 20" Marlin 1894CB.
A powerful, compact, seven shot six shooter in .327 federal on a .22 frame. You can do just about anything one would reasonably expect with very near .357 oomph on a small frame. I love it.
Still working on those 133gr. Keith SWC loads. Maybe a close range cow elk in store next year. I have thousands of .32 71 grain cast boolits, gang molds in 95 gr RN, 120gr SWC, and the aforementioned 133 gr. I very, very rarely shoot anything else the last few years, and I hand load for 28, I think, cartridges. With handloads, it is my .22. To me, the .327 is perfect. Very, very versatile, just as useful as any .357, and all on a smaller frame. The S7s are actually lighter than the S6 due to the bigger holes, and more of them. My EDC is a Single Seven.
