Default 10mm vs. .357 mag ballistic gelatin test


.357 mag Prograde 180 gr XTP fired from 4" barrel S&W Model 13 through four layers of denim into calibrated gelatin.

BB: 600.4 fps, 3.7"

Impact velocity: 1,078 fps
Penetration: 22.4"
Retained weight: 179.5 gr

No expansion.




10mm Hornady Custom 180 gr XTP fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin.

BB: 600.4 fps, 3.7"

Impact velocity: 1,261 fps
Penetration: 15.9"
Retained weight: 176.8 gr
Max expansion: 0.761"
Min expansion: 0.583"

Sorry, but I experienced an operator induced malfunction on one camera and missed the side shot of the gelatin.




Okay, in all seriousness, that really isn't a fair comparison. Sure it's the same bullet weight and sure it's almost the same barrel length but we don't measure revolvers the way we do autos. It's also a VERY heavy weight for .357, while it's middle of the road for 10mm. The .357 load was probably intended for use in a much longer barrel. I intended to test it in my wife's .357 Rossi M92 but I only had two rounds and the first exited the side of the block.



Bonus happy fun time with Desert Eagle, levers, and 37mm.

Nice camera work. Try some 125 gr Fiocchi JSP or HP ammo in your 4" revolver. You will get much better performance and your wallet will be a little heavier. Both Fiocchi loads can be found for around $20 for a box of 50. A 125 gr Fiocchi JSP was clocked at 1,700 fps from Ruger Blackhawk with a 6" barrel by the chronograph at the local sheriffs department. From a Ruger LCR a Fiocchi JSP will travel at close to 1,400 fps.

I have not clocked Fiocchi HP ammo. But I would bet you will see similar results. Both bullets expand very well. The JSP penetrates very well with an excellent wound channel on deer.

Napples n noranges. A real comparison would be the 41 mag. The 357 grain XTP was designed for much longer barrels like 18". I like 158 grain SJSP 357 in the rifle. A 140 grain or even the 158 grain 357 would be a better comparison. The 10 mm is a great cartridge and was the optimal cartridge the FBI came up with but not a lot of people can shoot it comfortably. It really needs a heavy gun to control the recoil for the average shooter hence the 40 S&W. My thought is, if you need more power use a rifle or shotgun.

John_Deer, thank you. I do plan to test several 125 gr loads from the revolver and carbine. My goal is to identify a load that does well in both. 158 gr is probably the best bet there but the other 180 gr .357 mag load that I tested (Remington 180 gr SJHP) performed very well.

JTJ, as I mentioned in the OP, it's not really a fair comparison but the 10mm is a lot closer to the .357 mag in terms of energy and velocity in a given bullet weight than it is to .41 mag. It takes a pretty weaksauce .41 mag load to be close to 10mm performance.
