Gel test Results
As you hunt for the best self-defense 357 Magnum ammo, we thought you might enjoy seeing the results of some testing we recently conducted with calibrated Clear Ballistics gelatin.
We shot five of these Speer rounds through a four-layer cloth barrier using a S&W 640. The results are detailed in the video you see above as well as the photographs. Through the charts, you should get a great idea how this Speer ammo stacked up relative to other 357 Magnum ammo products available to American shooters.
To get a better sense of our tests, be sure to check out all the protocols we followed when conducting our tests to determine the best self-defense ammo.

This new 357 round from Speer has a special nitche for Smith & Wesson J-Frame magnum revolvers. Lighter power (and recoil) than a standard 357 but delivers more punch than a 38 Special +P round. The larger frame revolvers can handle full power 357 magnums. The perfect ammo for my Taurus 617. Very accurate and a good self defense ammo.

This new 357 round from Speer has a special niche for Smith & Wesson J-Frame magnum revolvers. Lighter power (and recoil) than a standard 357 but delivers more punch than a 38 Special +P round. The larger frame revolvers can handle full power 357 magnums but until now the J-Frame magnums have been tough to handle with full power loads. Try these in your small frame revolver and you will be pleased.
