Subsonic 7.62x54mmR Round?

Post by Kiskaloo on Sat 8 Nov 2008 - 13:50

Has anyone heard of a subsonic round in the 7.62x54mmR caliber? I've tried a Google search and looked at some specialty ammunition manufacturers, but I am coming up blank.

Rico's SVD is chambered for this round, but while I can find sound and flash suppressors for the rifle, is the bullet if leaving at supersonic speeds, well... I understand range is going to be compromised but I am looking at ~100m which should be a cakewalk for her.

I can always just equip her with something else, but I was wondering if anyone knew of any.

I don't think there is such a thing, kisk. I know there are sound suppressors for Dragunovs, but they leave the spitting sound of a supersonic round. It's not silent, but it's far from an unsuppressed gunshot:

I'll be honest I haven't looked, nor do I plan to look. Still while there might not be a mass production subsonic round in production it's should be fairly possible to produce one. All you would have to do is load the shell with less powder. You could probably use something like wood dust to make up the missing volume, or just put divets in the brass. I think they did that a bit in world war one with 'guard rounds.'

I just decided to have Giuse use the WA 2000 since they make subsonic .300 Winchester for it.

Not that easy. In a large volume casing like the 54R, a smaller amount of powder can result in detonation. What you end up with is similar to a squib load, where the bullet gets lodged in the bore and the pressure has to go through the action to release. At the least, you kill the gun. At worst, you kill the user. Handloading is as much an art as science and there are dangerous areas for many powders that you simply don't mess with. Too little Win 231 in a pistol cartridge is an example. Bad stuff starts happening when you're burning the powder faster than the pressure can build.

You pick a gun by it's capabilities and if you want to suppress, you go for a larger grain, broad-nose bullet, like the 300 Win Mag.

I imagine the SWA Armory has the tools, tech and training to create subsonic 7.62x54mmR rounds should I ever find myself in a situation where a character is using a weapon that fires such rounds and needs the capability.
