Thanks for the link-good info!.357 magnum fro 2 to 18 inches. It's a great web site for many calibers.

"With the advent of compact 9mm pistols a snub 357 makes less sense than ever."
^^^^^This^^^^^
I don't follow the theory some folks have of if one is shooting a snub .357 you might as well be shooting .38 special ammo in it. I ain't buying that one and on-line internet data ain't selling it to me
The way I see it is if you are carrying a 2" snubby, terminal ballistics @ 25 yards isn't of major concern. At typical defensive ranges there is really no need for anything magnum, so why put up with all the disadvantages. At 2 - 5 yards the only difference between a 38+P and a 357 is how far the bullet will go after it exits the target. If you want more thump, go fatter rather than longer.
BBTI is a great site, but please note their statement of how they test:
"One note: in every case with the T/C Encore the length of the barrel was measured from the end of the barrel back to the breech face. This is how semi-auto pistols are measured, but revolvers are measured as the length of the barrel in front of the cylinder gap. Take this into consideration when comparing calibers using our numbers."
In other words, in order to compare BBTI data with a REVOLVER, you need to add the chamber length to the BBTI barrel length. A 4" BBTI barrel is close to a 2" revolver barrel.
This makes a huge difference, as the 2" BBTI test would approximate a revolver with almost no barrel at all!
