I recall a great video from Jeff Quinn where he chronographed Single Seven revolvers in three barrel lengths.

Everyone expects the longer barrel (7.5 inch) to give more velocity than the 5.5 or 4.5 inch yet the data (well taken and documented) showed the long barrel in THESE 3 guns to be slowest by something like 100 fps. I can’t find the original work. It was a head scratcher. The 5.5” was about 100 fps faster than the 7.5 inch with same cylinder gaps. Not the theoretical expectation for .327 Fed Mag.

Given that level of variation and the variation between batches of ammunition, I would be very skeptical of any data between any well made revolvers. Controlling the test ammunition is one huge variable. Getting enough sample firearms to be meaningful is another hurdle.

But.. if your goal is velocity I would recommend a Freedom Arms single action .357. The cylinder gap is tiny. This also means it can be fouled easily. For really reaching out, avoid the cylinder gap and go single shot.

I am remembering Jeff Quinn. He always had something nice to say, and found the good no matter how wretched the pistol. Still, you always knew when he really liked something. I absolutely trusted his reviews and he was one of those fellows you think "I bet it would be fun to have lunch with this gentleman." Rest in peace.
