yeah
I have been intensely interested in subsonic rifle loads for a long time now.
You have 2 basic options to pursue: heavy (usually soft lead) for caliber projectiles and very reduced powder charges; or
itsy-bitsy little projectiles (pistol projectiles in rifles, or else buckshot, etc) and very very very reduced loads- sometimes primers only.
BTW: you will get all this off of the arcane site mentioned above. i have found a few other references, and if i get them all in one place i will happily share them.
For the smalll projectile loads: One option, a sort of cheat method, is to use a cartridge adapter/chamber insert. They come in various configurations but allow fo rexample a 32ACP to be loaded one-at-a-time into 308 or 30-06 chambers and fired. These are subsonic rounds. The 32-ACP-30-06 uses a same caliber projectile so the accuracy is pretty good. Some use sub-caliber projectiles, mostly allowing 22LR (or, what i use most 22 Subsonics or even colibris) to be used in larger bores: 30-cals, 45 colt, and all the way up to 22-in-12ga shotgun. But these may not be what you want.
I know what I want REALLY is actual subsonic rifle loads. So...
well, heres one of the 'use at your own risk' ones i found for 8mm mauser:
Bullet Weight : 125
Bullet Type : Cut down Lee mold, cast wheelweight
Bullet Diameter : 323
Powder Manufacture : allient?
Powder Type : Unique
Powder Weight (Grains) : 5
Primer Manufacture : any
Primer Type : any
Brass Manufacture : reformed 30-06
Velocity : 925- 1025

I have some more info on another file- can't get to it now. I'll post back Monday sometime.
But not alot of folks have worked these up. I even spoke with folks from other countries who offered suggestions, but cant export ammo to us hre. BTW: Quality Cartridge will work up a load for you, but you have to order a few hundred bucks worth for him to do it.
One last intriguing tidbit: In my search for the elusive 8mm Mauser Nahpatrone, which uses the mystical Platzpulver 33 blank powder (supposedly similar to VV N310) I came up with these Prvi Partisan M69 blanks:

actually, OLD Western Scrounger sells some! Here:

Now these blanks are not quiet, they are designed to cycle machine guns. But, maybe the powder has the desireable characteristics?
I dunno.
This is a work in progress fo rme, too.
