Has it been done? Converting SKS to 9x39mm

[bryan.14]

I was wondering if anyone has ever converted an SKS to 9x39mm.

Looks like an interesting cartridge currently used by Ukraine/Russia.

It could be called SKS Vintorez or VSS Simonov.

Where would you get the ammo?
My understanding is the SP5 and SP6 are not available for export.

You'd need a chamber reamer and a bore reamer. If the SKS barrel is pressed into the receiver, good luck getting it off without damage. Secondly, remember the barrel walls are optimized for light duty firing cycles (by expendable peasants). Do you want to take that risk?

Ahh, great gun wisdom from President Biden.

Did the Russians go with .365 Makarov diameter or .355 ?

i thought they went with the larger 9.3mm diameter ( 3.66 ) or something close to that ..... at one time i was thinking of building one and using a 285 grain cast bullet from my other rifle ( a 9.3x62) .

The 9mm conversion (.366tkm) that you just discovered was shared a month ago.

 

[RRH.01]

You shared the chambering so what? The OP asked if anyone has converted one, so I shared a video I recently seen of one converted. Exactly like he was wondering. I didn’t just discover it, just jot a forum I frequent. Commie name, 541 posts, every one sks related. #### it’s one of those dorks…

Neat history on the Makarov... off topic a touch mind you.
They purposely loaded it down to ensure it couldn't actually used against themselves effectively.
Or so the article claimed.
