So lets talk about your favorite<(snip)>Subsonic load!
Wow! So work your way down to the point of not cycle, then back up! Now we talking! And this is why we hand load! custom load for host gun via. suppressor!Not all of them, especially not all Handloads. Though, generally, 147s are subsonic in factory loadings. Depending on host firearm or course, as the suppressor is extra, albeit inefficient, barrel length.
I cut out the 9mm part, because favorite isn’t what I call it, and it isn’t 147. Slow can be done with lighter too.
Speaking in generalities, the “best” suppressor oriented handload for any firearm will have the fastest burn rate of powder suitable for the cartridge, with a bullet whose speed doesn’t break the sound barrier. So heavy ones are easier.
You already know about the heavy part it seems, so let’s talk about gas.
Even though a suppressor will quiet any shot, it will have a lot less work to do, and do it more effectively, with a powder charge that has a lower bullet exit pressure. That means a faster burning powder. A faster powder will use less powder in total, and have less pressure behind the bullet after the barrel for the suppressor to capture. (And release slowly.)
In addition, depending on the host weapon, when the action opens there will many times be a lower residual pressure, which is nicer to the ears.
Slower powders will try to burn inside the can too, causing a louder shot. The can acts like more barrel, burning the powder in it, instead of trapping the already combusted gas.
So, Bullseye, HP-38, Ramshot Competition, and the like are the types you’re looking for as “Best”. But, even Power Pistol has a Sub-Sonic load.
Start at Start, then work down until the pistol won’t cycle anymore. Then go back up from there until it holds the action open on the last round every time. This will be the least amount of powder to work the pistol, and should be the quietest way to go about it.
The trick is getting the very most pressure out of the least amount of gas volume, no sending the bullet and putting enough energy into the slide to cycle, while having everything as close to depressurized when it opens as possible. Because for a semiautomatic pistol the most noise comes from the action at ejection.
As far as the 22LR, get 40grain Standard Velocities, smile at the Hollywood quiet!
I use my minor loads for gun games. Small charges of fast powders is what use 3.1 grains of N310 or 3.2 of N320 & Titegroup a with a plated 147 is pretty good. You won’t get the best accuracy out of plated bullets but they do the job most of the time…
excited about suppressor! now the 8 month wait. But I got 2, so that should keep me busyFind the load that gets to the velocity you want using a lighter charger of fast burning powder, while obviously staying under the safe pressure maximum and still cycling you chosen gun. By using the lighter powder charges of fast powders you produce higher peak pressures for a clean burn but less total gas volume that your suppressor have to slow down at muzzle exit. In my playing with by 300 BO I found that while 1050 fps is sub sonic and has not crack if you drop the velocity down to 970-1000 fps it is noticeably quieter than the usual 1050 fps that most subsonic loads shoot for. That said if you looking to maximize energy than obviously you want to get right up to 1050 fps.

Hopefully I’ll forget I ordered and it will be a suppress in 8 months or so!Ordered my first one, a rugged obsidian 45, back in early August. The closer it gets to that 6-9 month period the longer the wait seems.
No, not in all guns.....for sure.Ummm. Aren’t all 147gr 9mm loads subsonic?
currently waiting in line for a suppressor. Silencer Central is doing most of the work.
So lets talk about your favorite 9mm 147g Subsonic load!
got the Banish 45 & 22K
Win231 is Universal!For 9MM suppressed loads I've been using 3.5 grains of Win231. It's been very quiet in a variety of hosts and cans.
Win231 is Universal!
I got some HP38! good stuffNo..................231 is 231 or HP38
Universal is Universal..................
I got a ton of berry 147 from the panic days! but some 160gn heavy 9mm would be BOMB!If you look around Fiocchi, SBR, and Prvi Partizan sell a 158gr 9mm subsonic load. Advertised velocity is usually between 850-950 fps A buddy of mine has a 9-inch belt-feed 9mm upper and the rounds are still subsonic even with that length barrel. I suspect they would still be subsonic even in a carbine. Very quiet rounds if you're after quiet.
Hodgdon has a nice batch of reloading data for a 160gr coated bullet in 9mm. I would think from that data one could safely work up a good subsonic load for their favorite 158-160 gr lead/coated/plated bullet.
