We test fired five rounds of .357 Sig Speer 125gr Gold Dot into synthetic ballistic gelatin to observe its expansion and penetration characteristics. The ammo was fired from a Glock 31 pistol at a distance of 10 feet. A four-layer barrier of heavy fabric was placed in front of the gelatin to simulate clothing.
The complete data for this load from our test can be found on the chart below. The photo slider displays the expanded bullets that were retrieved from the gel. Pictured below is a high speed video that shows the bullet entering the gel at approximately 10,000 frames per second. The diagrams at the bottom of the page should give you an idea of how this load compares to other .357 Sig loads.

Works Great On Hogs!
Review by Bob
I took about a 120 lb. sow hog at 70 yards with one round of this ammo from a full-size SIG Sauer 1911 Nightmare. The impact literally dropped it in its tracks. And no that is no BS, I have a witness. From my perspective, this indicates that Speer Gold Dot ammo has earned its reputation for accuracy, reliability and self-defense performance. This ammunition does cost more than most 125 Gr. .357 SIG loads but IMHO you get what you pay for in this case.
