9MM Over penatration.

[275RLTW]

Know if that 124gr Federal HST is available locally? I hate to pay shipping (and hazmat?) on one measly box of ammo, can't afford to buy more. Especially when I have tons of 9mm plinking ammo loaded up and components to build thousands more.

Check Jax in FOCO if your up this way. I'll double check next time I'm up there.

Yep. 147 gr is meant for sub guns (MP5 & such).

New production 147 grain ammo such as the HST is not meant for sub guns.

I sure didn't know that! Thanks, you saved me from buying the bullets to roll my own!

And me drive to FOCO?! You have a better chance of having lunch with Elvis! I'd pay the shipping before my cheap ass would burn $40 in gas to drive that far for a box of ammo! I'll find some locally, or buy the bullets and make my own. Carrying a 9 is new to me, I'm a .45 fanboy. But now I have a Hi-Power clone, and my 9mm RIA 1911 is proving to be the most accurate pistol I own. Many thanks to whoever I bought that from!

I always wonder about folks worried about overpenetration. The real question isn't: "What happens to my bullets after they've lost almost all their momentum passing through a bad guy", but "What happens to the bullets that miss the bad guy because I've got about 9000 times more adrenalin coursing through my system than I've ever had and I'm shaking from it and it's dark and while I'm not firing blindly my muscles are on autopilot and <click click click> how did I run out of 18 bullets so fast and I hope everythings ok"

You ain't the only feller wondering such things.

Having shot quite a few animals up to and including deer with hollow points, I can tell you that I am far more concerned with underpenetration than I am about overpenetration.

As is just about every other heterosexual male on the planet I suppose.

Married, so I get it quarterly whether I need it or not. Cue the house music.

Late to party- as usual.

It was already corrected, but to say it again... New 147gr defense ammo is NOT built for subguns. ColoCCW is working off of some VERY old data referencing the first 147gr bullets designed for increased accuracy out of some mp5 for SF folks. Testing on 147HST gives reliable expansion (best I've seen- anywhere in 9mm) and penetration of ~12" through FBI standard calibrated gel out of a 5" barrel.

I wouldn't worry about over-penetration. Worry about under-penetration. Brassfetchers has nice ballistics visuals as well as diagram showing just how much of target areas are covered by bone. Another thing to worry about is bad angles can vastly increase depth needed for ballistic effect (so can fat... And the majority of Americans walk around with a good 4-6in of it around vitals). Some Google image searching will yield plenty of pictures of rounds from some very large handguns stopped on top of a sternum. Also, things as simple as down jackets have shown to reduce penetration to under 3" in skinny bad guys being shot with FBI approved, department issued .40 180gr gold dots.

my work has me manipulating human tissue with all manner of tooling and I can tell you from experience- the layers of connective tissue,cartilage, and bone that cover the center of the chest will stop MANY ballistic objects. I have found buckshot lying on top of cartilage before.

i prefer the 147s because they shoot identically to my competition load and give the smoothest, least snappy, fastest recoverable recoil impulse I have found. Yes, all 9mm is fairly manageable, but I can manage .16-.20sec split times and stay in a vitals zone on a silhouette at 7yd all day with these.

I do whatever DocGKR tells me to do. Win Ranger T or Gold Dots, whatever I have on hand.

+1

DocGKR is a good source for scholarly ammo testing.

Picked up the last two boxes of Ranger RA40T at the local Knoxville gun shop.
