I didn't realize 9mm could even do this! I knew it could push lighter bullets fast...but this is above much of the 10mm I've chrono'd in terms of energy.
do you have a 9mm carbine? between these and the G9...I'm half tempted to buy one. But what I really want is for Ruger to make their LC available for 10mm. These Civil Defense in that cartridge is the next video I am working on. Those were 60 gr >2350 fps / 750 ft#. Imagine THOSE from a carbine, too?
@@ShastaBean Yeah I have an AR9. Right now it is loaded with standard 115 hollow points as a house gun. I put a heavier buffer in it and going to run some +P+ 9MM BPLE.
@@ShastaBean It looks like the 5.7 has a slightly larger case volume. It's possible to stuff enough powder into the 5.7 case to risk blowing up the gun. This is really strange. I sent an email to Liberty Ammo to see if they can shed some light on this topic. Maybe there is some new powder on the market that Liberty ammo is using. Kind of like Hornady in their Superformance line. Or the 5.7 is just flawed and can't be improved upon.
@@ifinishedelementary yeah, it's a good question. Like I replied to Bill...I didn't realize this could be done with 9mm. It's above ft# of the some of the 10mm I've chrono'd. And you are right, that the volume is slightly higher in 5.7, which I wouldn't have guessed. So it could then be that more powder can still go into a 9mm, due to bullet length + the bottle neck part not really being able to take powder and the 5.7 bullets being longer? Dunno. I did just pull a 9mm bullet just to see its length. Fed FMJ was .5940. The 45 gr TSX is .6970. The 40 gr Nosler BTLF is ~.8100. I'd be interested to see what they come back with if you get an answer. When I compare the charges I'm working on with the 45 gr TSX, I've gotten up to 7.3 gr of Acc #7 with the latest primers and didn't pierce them. I might be able to get 7.4...we'll see. But with 9mm, same Acc #7 I see a 90 gr TAC-XP the Hodgdon data says a max of 8.0 and 8.2 gr for 115 GR. BER RNDS. That leads me to believe it would probably need an even higher amount, for a 50 gr bullet? Maybe 9.0? But I suspect they have a magic powder like you suggest. The fact the box says 2040 fps, and I (and now I see others) have measured above 2150 fps...? dang! Let me know if you get an answer. Now I'm curious.
@@ifinishedelementary oh, and if you do get a dialogue with them...I am also SUPER curious if they can tell you what pressure these rounds are reaching. That book data I mentioned says the 9mm 90 gr Barnes w/ Ac#7 8.0 gr is 34,900 PSI. Vel stated is 1242 fps, for an energy of just 308 ft#. Sooo...~520 ft# from these??? +P max is supposed to be ~38,500? These have to be well into +p+ realm. Whereas the book says the 45 gr Sierra Hornet w/7.4 gr says 45,400 PSI. I pulled a Civil Defense and bullet is .4990" (so, comparatively shorter) and powder charge is bumping up against 8.7 grains. It looks a lot like Acc#7, but maybe not exactly. Didn't take the time to dump some side by side. OAL was ~1.1100

i BET THESE ARE SMOKING OUT OF A CARBINE.

Any idea why they can get such velocities with a 50 gr bullet and the 5.7x28 can only get there with 30 gr bullets?
I don't load 9mm, but I expect it's a matter of case-volume and 9mm can use more powder
