My peeve is with people's insistence on using expensive, boutique, 20 per box, hollow points as carry ammo.
They are the manufacturers' money makers. Their 20-rd boxes of self defense ammo cost more than their 50-rd boxes of target cowboy plinking ammo. Why? Because they are really good salesmen. And a lot of the 'experts' are sponsored by them.
People, the makers are playing you. They will keep making better and better, more expensive HPs that will magically expand and stop just short of exiting the bad guy. They suck you into their game to sell you the Goldilocks choice of the ones that are 'just right'. New and improved. Sexy. Best. 'Ours dump all the energy into the target.' 'Ours will expand more reliably' But not always.
They also sell velocity, and lie about it right on the box, because HPs depend on velocity. Velocity comes with recoil. That's also unnecessary.
You're simply drilling a hole in somebody. Deep holes work. No expansion is necessary. Exit wounds are ok. But you have been taught to fear it in order to sell hollow points that won't exit.
The 50-rd boxes of LRN, FMJ, WCs, SWCs, RNFPs, target / plinking ammo are all killers.
Believe it or not the bad guys don't just shrug off the wounds from them. Neither would you. Are you more confident, does it give you more courage, knowing that the bad guys are all using 115 FMJ 9mms? Are the BGs somehow tough and immune to non HP ammo? You're not. Don't attribute the BGs with more resistance to being shot than you.
"Using non-HP ammo will get you killed!" Really?
The hole bleeds along its entire depth. Why even take a chance that the high velocity, heavy recoiling, expanding bullet will stop short of damaging EVERYTHING. There are more veins, arteries, organs, bleedable tissue in front of where that bullet stopped.
End of rant.
I see it all the time on a local marketplace website here in VA. Any Glock that’s been “customized” or “improved” or “enhanced.”
