Has anyone tried to use the Hornaday 150gr SST bullet in the 7.62x39. Will it fit? What kind of results if any, are you getting?

If your referring to the .308 version of the SST,then I would say you might get spotty accuracy.I'm not sure what the bore on the XCR would mic out at,(I would guess .310)but the Russian 30 caliber was .311,and not .308.I don't handload so I'm not aware of Hornady making a .311 SST,this is all I could find on their website.https://www.hornady.com/shop/?ps_se...&category_id=b30b914a0297302107cd8c4695880db5

What DTOM said.

I tried reloading the 7.62 Soviet, and I even tried stuffing some 308 bullets in there. The results in my rifle were "less than ideal".

From what I've HEARD (note, not done, just heard) the Roooooger mini-30 uses a 308 barrel. Might be worth trying if that's what you're loading for.

FWIW, the Hornady 150SST is my "chosen" bullet for a do-all. But I'm loading it in the 7.62 NATO, so that's very different.

I'd think that the bullet would be a bit too long in a 7.62 Soviet, and that to keep it at mag length you'd have to knock down the powder charge significantly.

FWIW

Huh?

Cu 8.9 g/cc
Pb (lead) 11.3 g/cc

You can't make a shorter bullet w/ Cu than Lead (for same profile and weight).
Now if Barnes would build an MRX..... (W - Tungsten core - 17.1 g/cc)

7.62 NATO uses .308 bullets
7.62x39 uses .311 bullets

Also a 150 grain bullet may be a little long for the x39 case, leaving less than ideal powder capacity.

If you want to try heavier bullets look at 303 British or 7.7 Japanese tips, there are some lighter versions out there that may fit the x39 case.

Not enough case, 7.62x39 for either the bullet or powder. A bullet as heavy as the 150 gr .310 or 3.11 would sit too deep in the case. For an AK or SKS the 130gr bullet is about the heaviest loadable (with safety in mind). I would stick with what it was designed for a 120 - 125 grain bullet. A Barnes all copper in 125 grains would be whipass. :2cents: ;D Same goes for an AR or XCR in 7.62x39, the heavier the bullet the deeper it would have to sit in the case to fit the magazine. :2cents:

I should have made this point clearer in my first post. I was planning to use this in the XCR kit. So I guess I should ask: What is the bore diameter of the XCR in 7.62x39?
