Pitting .357 Magnum against .357 Sig in a gel test (VIDEO)
While both of the chamberings have their dedicated fan base, Kentucky Ballistics sends the debate to the gel to see how they stack up.
As a control in the tests, Todd with KB uses Underwood Ammo factory JHP loadings across the board including a 125-grain Bonded and a 147-grain XTP in a Glock Model 31 for the .357 Sig while the Magnum loads are 125-grain XTP and a 158-grain bonded out of an S&W 686. While the Glock has a half-inch longer barrel than the Smith, the .357 Sig loads are also cataloged as having a velocity in the 1250 to 1475 fps range, which falls short of the advertised 1500 to 1700 fps velo on the Magnum loads.
Still, when fired into Clearly Ballistics blocks, the results are interesting no matter where you stand in the debate.
