Here's an old wetpack test I did over 3 yrs ago. FWIW
Range test using a sloppy wet newspaper wet pack and 4 different ammo types follows. Fired 4 rounds each and saved 5th round for setback/pull measurements due to recoil. No setback/pull seen on any brand. (Ammo is what I could find locally, so that's all I tested.)
Remington .357 Golden Saber 125gr. Best cartridge tested. Recoil very manageable. Average expansion 0.625" and penetration full 11" of wet pack stopped at plywood backing. These results equal FBI data for a 4"barrel on firearmstactical. This will be my carry ammo. OAL 1.5625".
Winchester .357 Silvertip 145gr. This is hot stuff and strong recoil. Would not want to shoot much of it (what to do with rest of 50 round box, too much recoil for me.) Average expansion 0.655" and penetration 10.5" in the wet pack. However, the petals tore off on several of the rounds as shown in the picture. This would be a killer (you) in a lightweight Sc/Ti snubbie and in +p it would be awful!!
Winchester .38special + p Silvertip 125gr. Very good ammo. And contrary to a lot of old reports (ammolab) all rounds expanded equal to FBI test data. Average expansion 0.547" and penetration 10" in the wet pack. Recoil a tad less than the Golden Saber .357. OAL 1.4687" is good in the .357 chamber.
Winchester .38special "USA" whitebox FMJ 130gr. This will make a nice target/practice round. Low recoil. Penetration full 11" of wet pack and into the 1/2" plywood backing. One round went thru the plywood and gone. Recovered bullets in photo measured .356"max. Cartridge OAL 1.531" very good.
All spent cases looked good with no cratering of the primers. The pistol functioned fine, no problems other than my POI needs to be better. Photo of results below.
And BTW, initially I got a box of "WinClean" 125gr. .38 jacketed soft point. But took it back due to this stuff is too short OAL compared to others. It measured 1.4218" OAL which actually is less than SAMMI recommended minimum of 1.425" So don't buy any of this for use in your .357 revolver, bullet will have to 'jump the gap'. It might be OK in a plain .38special but not .357. I didn't like the exposed lead on the bullet either.
