It was nice and warm after today's rain, so when the sun came out, I decided to run a few rounds through the chrony. Sometimes flash and recoil don't count for anything toward knowing what's really going on.
I took three guns out today, the .357 Mag Handi Rifle, a Model 66-2 4" and a Model 625-4 with a 5 1/2" barrel. The Handi and the Model 66 are more or less companion guns that theoretically shoot the same rounds. The question is, what is a single good load for both guns and what kind of performance do I get for that load? The reason for including recoil numbers and Taylor KO (KO) is to give a little better idea of what to expect on both ends for terminal results. Muzzle Energy (ME) just doesn't always tell the whole story. I suppose everyone knows I shoot with the chrony at 15' and then convert those numbers to Muzzle Velocity (MV).
Here's the numbers:

The two outside holes in the next target are from where I was running rounds through the chrony and was too lazy to change targets!
