Got a new toy. It's my plandemic osprey9 sealed and recoil boosted. Who'd da thunk the plandemic would still be going strong a slow tax stamp later? (13 or 14 months, my slowest of 6 form four silencers by far)
The gun is a Beretta 92fs.
To really test out this new fangled Nealon device silencer I dropped some 380 with 90gr bullet loads in 9x19 cases and it cycled. I was trying to make it malfunction, without the silencer it definitely would not cycle.
Usually I load 9mm pistol with medium speed 9mm powders like unique, AA7, HS6, I'm starting to load all my 115gr with faster general dynamics cbi which burns a lot like universal in a 9mm.
I usually don't load faster than cbi or HP38 in any pistol.
So completely opposite of how I normally load. I'll be loading a "powder puff load" and I kind of despise loads like these because an accidental double charge is possible and they tend to run dirty.

For my clandestine 9mm loads they need to:
1, be quiet enough to not wake the baby when eliminating coyotes or other preds around the hen house.
2, The osprey is sealed so the loads have to be clean burning, bullets jacketed, ect.
3 use fast powder, as they are usually quieter.
4, don't have to necessarily be able to cycle the gun without the osprey.

But fast burning normally doesn't equal clean burning. Another reason I don't like fast powder puff loads.

I do have a pound of Nitro100 NF, that's the fastest burning stuff I have by far, next to that it's probably HP38. A big gap there. Nitro 100 NF is supposed to burn pretty clean in 9mm and make decent plinker loads.

So I was thinking 115gr, subsonic.
Should be pretty quiet?
I'm very sure those "380 loads in a 9mm shells" 90gr rounds were subsonic and still cycled.

The brass I'll use will be Remington, or some other average capacity no thrills case as I have a few hundred of each of them. Primers will be cci, bullets will be Sierra 115gr HP.
I could use Sierra 90gr 380 bullets.
I don't want to use 124 or 125gr bullets as I save those for my hot 9mm carbine loads and 147gr bullets for normal P and +P pistol loads but I can use them.

Anyone use nitro100 NF for 9mm?
With or without a silencer?
Anyone have any pet loads for nitro100 NF in a 9?
My load manuals don't have any nitro100 NF loads listed. I could just treat it like reddot, titewad, clays, ect and work up a load.
 
Looks like for 115gr jacketed bullets my load range is 2.8 to 3.4 grains. Man this stuff is viciously fast.
No velocity numbers with what I found but I bet if I looked up the fastest powders listed using about 3gr they would give me an idea.
 
I agree with wreck-n-crew. You are going about it backwards wanting to run 90 grain bullets.
A 147 hp would be a lot easier to load subsonic. Not to mention more effective for a quiet coyote load.
I'd try to run the 90s in the carbine as a fast coyote load.
 
It's pretty easy to get a 124 grain load to cycle and remain subsonic. A lot of 115 grain bullet load data has starting loads over 1,100, however Accurate powder's online resource shows 2 loads with Nitro 100 and 115 grain bullets and both have Max charges that appear to still be under 1,000 FPS so that might work out just fine.

My favorite powders are Vihtavuori N330 and N340 with 124 to 147 grain bullets. It's real easy to get soft shooting, quiet, clean loads with these powders.

Well, I have shot them from upstairs (shooting from inside the house) without Mrs. Morris knowing. Although she did wake up with me getting out of, going upstairs and coming back down to get back into bed.

I setup a rifle so I only have to crack the door as the coop is only 60 yards or so away.

I just use my “minor” 9mm loads, 147 gn plated RN with 3.1 of VVN310 or 3.2 of N320 or tightgroup @1.160”

That said, I built my 9mm suppressors so I can disassemble them. If the can won’t come apart, I would stick to jacketed vs plated and reduce the charge but you have the right idea of picking a fast powder.

It’s hard to judge sound from video, much less one being shot from a cell phone held against the rifle to keep it steady while shooting but these are 3.2TG loads.
 
I wish I could buy big N powders.

Looks like Nitro 100 NF is the way to go. I found some 124gr plated bullet data. You hit full 9mm pressure at 3.5gr and are only doing like 950fps.

I probably will test 90gr bullets but would like to go with 115 or 124gr bullets. I would only use 90s if they offered significantly better accuracy which I don't expect them to. Every 90gr load I have tried in the Beretta gave less than desired accuracy.
 
Tests, well just a test.
I hand weighed four charges of nitro100nf at 2.6gr and seated a Sierra 115gr HP to a little over book coal.
They weakly cycled the gun dropped the brass at my feet, did lock the slide back after the last shot. No chronograph numbers as it was dark. Pretty quiet, I don't think they were supersonic.
Pressure signs were low, soot around the brass, ect. Primers were convexed. As if there wasn't enough pressure on them to push them out of the primer pocket back flush against the slide.
The 115gr bullets probably need more like 3gr of nitro100nf to run normally.
 
Here is a sig/Sierra 124gr 9mm bullet over 3gr of nitro100nf. It went through two 1 gallon milk jugs and 12 layers of cardboard. Should be deadly enough. No chronograph as it's dark out.
Brass ejects normally and locks the slide back. Probably load up some more at full power around 3.2 to 3.5gr, chronograph them and test them.

Worked up to 3.3gr of nitro100nf with sig/Sierra 124gr bullet. Sun was out so was the chronograph. I was getting between 955 and 1,013fps.
I don't think there's really room for a double charge, the brass would be almost all the way full.
 
I did some more testing. Heck they even cycle the sten and they are stupid quiet out of the sten guns 9.5 inch barrel and big no moving parts silencers.
I like this load I'll load up a few hundred.
 
Nitro100NF burns so violently, its more like it explodes so that the peak pressure produced seems to be more of a function of internal volume than bullet mass.
As if the powder has fully burned before the bullet can make the jump to contact the rifling.
The sig/Sierra bullet gives you a more internal volume than a typical 124 or 125gr bullet. I like it for my 9mm major loads cause I can load more real slow 9mm powders. Going to a typical 124gr bullet that sits further down in the case could be like switching to a 147gr bullet.
So be careful, powders this fast usually aren't recommend for pistol use.
 
I too have an Osprey 9. I've got a threaded CZ 75 Omega, threaded Beretta Tomcat Covert, a VZ61 and a couple of PCC's that I shoot regularly with it.

Hint: Keep the linkage for the lock cleaned with WD40, A LOT. Any residue that builds up will cause it to bind, and bend the lever, which will make it loose. SilencerCo will fix it no prob, but prevention is easier. Also, while it's rated for 300BLK subs down to a 7.5 inch barrel, that's the ragged edge for sure. Mine seperated and cracked after a heavy diet of 217 and 245 gr subs in a 7.5 300BLK SBR, Again, SilencerCo repaired without question, but I'd definitely recommend sticking to a 10 inch barrel.

Hands down, TiteGroup is the powder of choice for shooting with cans, especially with AR9 PCC's. The suppressor blowback can be 50 to 90 percent less, especially over powders like AA#5 which tends to burn my eyeballs out with the can (now I know how some of my old girlfriends felt - yet another load of guilt to carry around with me). Just works way better, and it runs extremely well when you're down into the small drop area, like 2 to 4 grains. That's more or less become my go to powder for almost any sub pistol cartridges I'm loading specifically for shooting with the suppressor.

My bullet of choice is the Gallant 147 grain Hi-Tek coated cast for 9mm, and Berry's plated 71gr for the Tomcat .32. 147's are definitely the easiest 9mm to load for shooting suppressed. Out of a 92, even hot 147's will be Subsonic, and will function with or without the can. 115's are very difficult to get down to sub speeds and still cycle without the can, but it can be done.

Oh typical max load for a 124gr bullet for nitro100nf is 3.6 to 3.7gr for plated and about 3gr for jacketed. So my 3.3gr load is over book. But they don't have a 124gr sig/Sierra bullet load listed. They have some +P loads and that much nitro100nf at the velocity I get is probably a +P range load.
Don't hot load 9 with nitro100nf.
 
Fired off some of these, the 3.3gr 124gr sig bullets. They chronographed at 950 to 1,030fps. Out of the sten with 8.5 inch M91 barrel.
They sounded like shooting a hot pellet gun with my form 1 silencer. These rounds cycled the sten, a little on the week side but half a mag cycled every shot.
 
I built up a nice 9mm load that works great in pistols and is still subsonic in a 10.5" carbine barrel.
3.8 grains of HP 38 under a 147 grain RMR FMJ seated to 1.14".
I'm sure a hollow point could be used as well.
Should be nice and quiet, and still get the job done. Burns cleanly and produces consistent velocities.

As for bullets... I tried both Berrys plated and RMR FMJ. They are both the same price, but the RMR grouped FAR better. RMR also has a nice affordable HP called the Nuke. Not much more than their FMJ... I think around $0.12 per bullet.

Ran through a chrono for five shots. (mixed range brass)
