32 inches of penetration from the Speer 158 gr Gold Dot .357 Magnum load could cause serious issues with over-penetration.

I do know that I'm done buying Speer Short barrel for my snubby and staying with Hornady 110gr FTX Critical Defense in +p...

Amazing results in penetration, MV and consistent bullet expansion!

I may try the 110 FTX standard velocity version in my Colt Agent (not rated for +P). They made the best showing for standard rounds.

It's really a very comprehensive study.  The pics of bullets and expansion are phenomenal. 

Mr LCR is rated for .38+p so I'm digging my Hornady out o the ammo closet..

None of the heavyweight Gold Dots seemed to expand that well. At least in .38 / .357.

I thought the whole idea behind Gold Dots was that they were supposed to have quick reliable expansion but the results show otherwise. Maybe I misunderstood but that's what I thought.

The 135 Gr. Gold Dots performed all but perfectly in the 2" and 4" .357's. It's the heavier 158 grains that don't expand. And over penetrate as a result. I'm wondering if the nose cavity is getting packed up with flannel, or whatever cloth they're using? And as a result they're working like FMJ's.

The Remington 125 Gr. Semi Jacketed Hollow Point's are still one of the best in a 2", .357.
