7.62x39 with heavies?

[brybenn]

In talking with a buddy about suppressed rifles and sub sonic rounds like the whispers and blackouts I had a thought would it be possible to take say a savage action and custom chamber it to 7.62x39 necked to 308 but have it throated for longer bullets? The soviet case firing 200+gr Amax or other target bullet should be or close to subsonic if I'm correct in thinking. This would be cheap minus the custom barrel but an easy and simple way to get a 30cal quiet target rifle for playing with. Just neck size the 39 case to 308 and go I believe. Any thoughts or am I just way off the mark?

I am not sure what you mean by this... you do know that 7.62 rounds ARE .308" right?

aren't 7.62x39 actually a .310 diam bullet?

the 7.62x39 rifles that use a .308 barrel have the slightly larger than normal sized throat ( normal to a 308 barrel ) so the slightly larger bullets can be used .

if a person can find a inexpensive 303 with a good barrel , these can make exellent rifles to rechamber into 7.62x39 .

Most 7.62x39 rounds are loaded with .311 bullets. Most match bullets are .308 diameter

Yes, I've done it and it works. I use the PT&G reamer throated longer for .308 barrels. I can fire military .310/.311 surplus anytime in them. It does work perfectly for long heavy bullets too.
BTW, we're not allowed suppressors as citizens here in Canada, so it won't be that quiet.

Ahh! Info assimiliated!

Thanks for the info, and setting me straight!

I know we can't suppress rifles here but it should be a lot quieter then my 2506 270 and 300wm. Thanks for the replies

What twist rate did you use?

 

[lejarretnoir]

For the heavies 9", 10". Overkill for surplus rounds IMO, but still shoot well.
For surplus and 125 to 150gr 14" works best. My 788 with a Shilen 13" twist fires 125 to 168gr equally well and getting 1" groups with Chinese surplus.

I have a Stevens/Savage I'm thinking of chambering to 7.62x25 Tokarev. This will also make a nice quiet round with heavies.
