Hello
Most of the 38 Special reviews that I did, in most cases, were shot with two guns.
A Taurus 85 Ulta Lite 2 inch barrel and a Smith & Wesson model 15 with a 4 inch barrel.
First I do forensic exam of the ammunition. Next I shoot a group while chronographing with each gun. 10 yards with the 2 inch Taurus 85 and 25 yards with the Model 15. Chronograph is a Oehler 35P
Then the ammunition is shot out of each gun into a 55 gallon plastic barrel of water. The bullets are then recovered, photographed and then measured for expansion. In cases where the bullet fragments and loses its jacket, a weight is taken with all the recovered material and also a weight taken with just the lead core.
Here is the link to all the photos of the review;
38 SPL B.B. 158gr SWCgcHP +P — Postimages

g/ch .38/.357 158 gr. SWC-HP per 100/ in a plastic ammo box
Here is the data sheet;

I was quite pleased with the expansion out of the 2" 85 UL. Velocities were pretty amazing in both guns. I wouldn't say the the recoil Taurus 85 UL was brutal, but it was awfully close. Even so, I would feel quite comfortable carrying this ammo.
I didn't shoot these in water as it would be obvious that they would expand very well..
