[Brian46]

what is the bore size on the 7.62x39, is it .311 to match surplus ammunition?

HHMMM!! I've been looking at the XCR in 7.62x39 also. I don't think it would be a deal breaker if .308 or .311? If its any help a quote from the Sierra reloading manual. "As a point of interest, we tried using .311" diameter bullets in the Ruger Mini-30 test rifle, as well as .308" diameter bullets in a Russian SKS. Although hardly an ideal situation, both combinations performed surprisingly well" My preferance would be a .311 bore. And I have no problem using surplus ammo in any gun!

Plenty of people shoot surplus from their XCR' so it should be .311

[Grumpy Wolverine]

You know I'll have to dig into that for you. I had thought that they were .311 but I want to check now to find out for sure. They shoot really well with surplus ammo in them.

[Niko-PG]

99% sure it is .311 but can't remember where I found the info.
Let us know your reloading results: I haven't been able to find a load that work better than surplus :-(

I have a keymod in x39 hitting 300 meter gong iron sights with ease using Romanian surplus

Savage uses a 308 bore and from what I can find they are not accurate, couple that with bi metal bullets in a tight bore and barrel life is reduced as well. Hopefully wolverine knows or can find out.

!00% AGREE!! My bolt gun in 7.62x39 is a CZ 527 .311 bore And the CZ 858 has a .311 bore also. Doesn't Wolverine have a AR type rifle in 7.62x39? What is the bore size on it???

[GUB]

Yeah, The Armalite M 15A4 Carbine in 7.62x39. What is the bore size on it???
