Both the 125gr and 158gr Gold Dot loads are very high penetration ammo, according to the testing I have seen from Speer, personally I would save this for hunting/woods ammo.

The design of these bullets is why they penetrate so much, combined with the velocity.


Our old duty ammo back in the day was the 125gr Remington .357mag, this bullet showed rather shallow penetration in actual shootings, again due to bullet design combined with the velocity it was being pushed at. The same bullet in the .38 +P expanded and fragmented much less, and penetrated more.
