Speer's Gold Dot Hollow Point ammunition is tailored specifically for home defense. Featuring Speer's bonded core technology, this round performs great in the FBI tests.

Speer's bonded core bullets are ideally suited for barrier penetration as the jacket is bonded to the lead core of the bullet. This prevents core/jacket separation which in self-defense situations would represent bullet failure. In self-defense situations, bullet weight retention is necessary to achieve the desired 12-18" of penetration. This bonded technology is designed to retain its weight through various FBI barriers such as the front windshield of a car to deliver the desired penetration.

This premium Speer 40 S&W ammo represents a great option for self-defense.

This ammunition is new production, non-corrosive, in boxer primed, reloadable nickel-plated brass cases.

Ballistic Gel Test

Ballistic gel test for 40 S&W - 165 Grain JHP - Speer Gold Dot - 20 Rounds

Ballistics Test Summary

We test fired five rounds of .40 S&W (Smith & Wesson) Speer 165 gr Gold Dot into synthetic ballistic gelatin to observe its expansion and penetration characteristics. The ammo was fired from a Glock 27 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 .40 S&W (Smith & Wesson) loads.

Q: Hi, it's alot of confusion regarding this particular round in 165gr. I have seen a youtube video from Alaskan Ballistics and he did a test with two different boxes of this GD 165gr ammo. One from the 20 rd box and one from 50rd box. The one from 20rd box got great results, great expansion and penetration. 1150 fps out of 4", exactly as advertised. Whereas the one from 50rd box had similar results to yours. Less velocity, almost no expansion and overpenetration. So i wonder, did the round you made this test with come from 50rd box? Btw thanks for your efforts, i appreciate it.

A: Thanks for reaching out Tony! That is inexplicable, because Speer packages the same ammunition in 20- and 50-round boxes. Please share the video with me so I can take a look and try to make sense of this!

Q: Thanks for the quick reply. Do you think you may have had a bad batch? I've seen other ballistics tests of the 165gr showing extremely similar expansion/penetration to the 155gr and 180gr. Just seems odd that these 5 shots didn't expand at all.

Posted On: 6/4/2021 By: John K

A: Odd indeed – I admit there may have been some peculiar defect with that lot of ammo, because Speer Gold Dot is without question some of the finest self-defense ammo on the market! But those were our results, and we don't try to hide anything when it comes to our wares. Unfortunately Speer hasn't published their own ballistic gel test data for this ammo (which they usually do on le.vistaoutdoor.com), so our own data is the best I have to offer!

Q: Did you notice anything odd with the expansion of these rounds? Seems that they did not expand much at all expecially compared to the heavier and lighter speer gold dots.

Posted On: 6/3/2021 By: John K

A: Thanks for reaching out John! We did in fact not witness very dramatic expansion from this ammunition. Still effective for self-defense, but the interesting results of our ballistic gel test should be taken into consideration if you plan on using this ammo:
