What Defense Ammo do you carry in your 42?
Underwood extreme defender 65 grain +p
the 380 is borderline whatever load you use, so I use the most powerful I can find -- Underwood
Underwood here, too. Either XTP or XP in their +p load.
Used to carry Hornady XTP Custom but have since switched to factory loaded Speer Gold Dot.
I keep two magazines loaded, one with Underwood 65 Grain Xtreme Defender and the other with Underwood +P 90 Grain XTP JHP. I keep the magazine with the XTP in the 42.
Underwood 90 grain XTP Plus +P.
Yes, if underwood. The bonded JHP's are gold dots. Otherwise at standard .380 velocities bullets either expand but don't penetrate, or penetrate but don't expand.
Critical Duty simply because it feeds well and penetrates deeper than Critical Defense. If not this, then any cartridge loaded with Hornady’s XTP bullet.
Speer knows more about making their own bullets perform than the boutique loaders.
Increasing the velocity causes the Gold Dot to expand too early. The factory loaded Gold Dots have found the sweet spot for .380ACP.
I disagree, kind of. Speer needs to stay within certain specs to allow most guns to function. Underwood goes beyond those specs, after all, that is what they are marketing. I agree, however, the higher velocity of Underwood will cause the bullet to expand earlier and usually not penetrate as deeply as lower velocity rounds. It's a question of more energy or more penetration... On 380 I choose energy rather than the FBI alter of 12 to 18. I have seen gel tests of 12 inches, so that is good enough for me. Either way, the cartridge is "iffy" at best.
I use Lehigh factory 90 grain Xtreme Penetrator ammo. The ammo appears to be barrier blind and provides adequate penetration without over-penetration in a standard velocity round.
I tried this with Gold Dots, and, although expansion was good, penetration was poor generally, and very poor when I hit a bone going in.
I agree seems not many people trust this new bullet design. I however after watching all the you tube vids. am convinced these are the way to go especially with .380 and .32 auto where velocities are low and penetration is needed with a pwc better than hollowpoints
In .380 XTP is the only bullet I'd trust.
The standard Gold dot is made to expand at standard .380 velocities. That's why Underwood used a BONDED gold dot which both expands and penetrates.
I’ve never seen a non-Bonded Gold Dot. Where did you find those?
According to Speer, all Good Dots are Bonded.
I forgot that Gold dots have a plated jacket. Regardless, the Gold dot at 1200 fps will not expand "too soon" and retard penetration. at 1200 fps it will both expand and penetrate.
At 1000 fps it will do a little of both but not as much.
