Thinking of trying Fiocchi 9APE 158gr
- Thread starter Hiller
- Start date
Found the violin case at a local yard sale with the violin still in it for two bucks. The foam I put in it cost more than the rest of the set up. Always wanted a machine gun in a violin case. Probably from watching to many old movies when I was young.

35 cents a round?

The fiocchi 158 I tried worked great in my Uzi suppressed. So I picked up a case for 353$ delivered. I know it’s kinda pricey but couldn’t find a better deal on anything with a 158 projo.
I like to reload my own but thought it couldn’t hurt to keep some new subsonic ammo around.
I heard somewhere that there’s no such thing as to much ammo.

Once ammo is subsonic, like 147 grain is, there is no supersonic crackle sound coming off the rounds. So why bother paying extra for an even slower round?
I chronographed Speer 147 grain factory ammo in my UZI and got 1,045 fps. That's about 50 fps slower than the speed of sound at sea level, which is 1,100 fps. So... no crackle.
Sure, you're getting close to going supersonic, but you're not. That ammo is well under supersonic speed, even given that a 10" barrel is going to push a 9mm round out about 50 fps faster than a 5" barrel.
In Denver CO, at 5,000 feet altitude, the speed of sound is still 1096 fps. It doesn't all change that much with normal ground altitude.
This makes me wonder what the heaviest bullet that can be stabilized by the UZI rifling is. It would be interesting to see if the 158 grain bullets start wobbling at 100+ yards.
Now that I think of it, this is kind of a selling point for Remington UMC - that garbage is so low powered that 147 gr 9mm would probably be a real nice suppressor round.

I like 147gr. Have to be careful with the 147gr ogive. Most 147’s have a flattish ogive and may not feed reliably in some FA uzi’s.
The Remington umc147 cycles my suppressed 8” barreled Uzi smg fine. Had a bullet jam between the bolt and barrel feeding off the right side of the mag. I felt the ogive on the umc ammo was potentially unreliable in my weapon. So I went looking for a different ammo and ended up liking the way the fiocchi 158’s worked for me.
YMMV.

If you happen to reload I use a 124g 9mm FMJ bullet and power pistol powder. The bullet clocks in at 900 fps or so and remains subsonic cycles the subguns and pistols no issues
