That is kind of like the old energy vs momentum discussions, or even a little penetration vs expansion stuff.I know this is not a gun forum but wondering about ultra-light bullets.
I'm so old that at one point I learned that low velocity (approx 850 feet per second) 230 grain FMJ 45acp was the ultimate self defense ammunition.
Now I'm seriously considering lightweight (50 to 75 grain) 9mm at 1600 to 2000 feet per second for self defense.
The advantages of the ultra-light + ultra velocity ammo are multiple but include very low recoil and seriously increased energy transfer as measured by foot pounds of energy (at short ranges).
Examples include but may not be limited to:
Liberty Ammo 50 grain, 2040 fps, 462 ft lbs energy . . .
Advanced PDF 65 grain, 1695 fps, 416 ft lbs energy . . .
Cor-Bon's 90 grain, 1500 fps, 450 ft lbs energy . . .
NovX's 65 grain, 1730 fps, 432 ft lbs energy . . .
Cor-Bon is probably the closest thing to a 'name' brand in this group. The major name brands don't seem to offer this ultra-light stuff. Hornady has some 100 grain ammo, which they market to women as low recoil (they even donate a portion to Breast Cancer research) but I'm not sure it is as serious as some of the above brands. Hornady seems to focus on the reduced recoil and feminine marketing angle more than technology in their marketing.
I'm currently using Hornady 115 grain JHP and Winchester Ranger 147 grain JHP as my primary carry and home defense rounds in 9mm ammo. But it seems like, at least at short ranges, the ultra light ammo might have serious advantages in terms of low recoil and high energy transfer.
Compare the energy of any of the ultra light ammo to my Ranger's 147 grain JHP which has a velocity of 985 fps and energy transfer of 320 foot pounds. The energy transfer of the heavier ranger to the ultra light stuff is literally 100+ foot pounds/25+% less than the ultra light rounds. That is significant.
I've never tried any of these types of rounds. Clearly for self/home defense they must be 100% reliable. But assuming they are reliable in my guns, it seems like switching from heavier/slower to much lighter/faster is a wise choice.
Just using LIBERTY's claims as an example:
- 32 to 38% less felt recoil
- - 65 to 75% more velocity
- - 25 to 30% more kinetic energy
- - Reduced over-penetration
- - More stopping power
Anyone try anything like these (in any caliber)?
Yes, agreed, this is pretty much that whole argument, taken to the extreme.That is kind of like the old energy vs momentum discussions, or even a little penetration vs expansion stuff.
These light weight, high speed rounds have high energy but they also have low momentum.
I don't like to go to an extreme in any direction. If I want more energy without losing penetration I would just go to a bigger cartridge.
Are those high-energy rounds performing anywhere near the advertised velocity out of that short barrel?Yes, agreed, this is pretty much that whole argument, taken to the extreme.
I actually split the difference, sort of. Decided to try a few boxes. I picked a bullet weight that is on the heavy end of the ultra-light spectrum (70 grain) but also with the highest energy (462 foot pounds) traveling at only 1700 feet per second.
Ultra lights tend to not penetrate deeply, so by picking a heavier ultra light, I figured I was hedging that bet just a little bit. But I never want over penetration (punching a hole clean thru) due to liability, and that should not be an issue. The biggest concern is probably heavy winter gear, like thick Carhartt clothing, some of the lightest weight stuff tended to rapidly slow down and not penetrate heavy clothing. But that was a real ultra light problem 15 years ago and newer bullet designs may have alleviated some of that?
As for more energy without losing penetration comment, I'm a died in the wool, confirmed 45acp 1911 guy, carried that for 30+ years. But switched down to a 9mm for easy concealment and lighter weight. Looking to optimize my new Springfield HELLCAT for old arthritic hands (added larger controls, changed trigger to one I can feel better), and fading eyes (added holosight + green laser to the tritium factory sights). Finding LOW RECOIL, but still viable self defense rounds, is part of this process (I did mention arthritis) to tame a snappy little gun that, with the added optics, weighs only 18oz.
I'd say yes - golf cart, grocery getter, ATV, snowmobile, prom limo - it does it all.can this count as a golf cart??

The velocity reports are out of 4" barrels, not 3" like my HellcatAre those high-energy rounds performing anywhere near the advertised velocity out of that short barrel?
It would in Hobart.can this count as a golf cart??

And given the ways they measure this stuff, the 4" barrel can be up to 45% longer than the 3". I bet that makes a significant difference in velocity.The velocity reports are out of 4" barrels, not 3" like my Hellcat
That should be on the Joke of the Day thread.I had my annual checkup the other day. At the end I asked my doctor what test was used to determine if an older person with reasoning problems might need to be put into a facility.
He said they use the bathtub test. They ask the patient, "If I filled a bathtub with water. Then gave you a spoon, a cup, and a bucket What would you use to empty it?"
I said the normal ones would use the bucket because it is faster.
As he picked up the phone to call Happy Acres Home, he said a normal person would pull the plug.
I like my room, pretty curtains.
Well I think the videos show actual 4" barrels that are not 5" barrels and of course there is some velocity drop, but most self defense ammo was tested out of 5" barrels and shot of 3.5-4" barrels so it seems like parity. Federal Hydra-Shok or Winchester Ranger or Speer Gold Dot is all going to test out of whatever they test out of and we have to take those numbers and adjust for our gun's barrel size.And given the ways they measure this stuff, the 4" barrel can be up to 45% longer than the 3". I bet that makes a significant difference in velocity.
Yesterday, my wife heard that Wheeler and the Union Township schools want to incorporate under the jurisdiction of Valparasio.Union Township schools passed a 21% last go around.
