"inherent" accuracy is a load of complete BS, Besides that what's not accurate about a cartridge that the PPC family is based from. You don't get more inherently accurate than PPC. People like you are the reason I'm building this rifle.

The reason rounds like 6mm BR are viewed as being more accurate is there aren't any crappy rifles so chambered. If SKS'es came in 6br people wouldn't think of it as an "accurate" round.

Like I said to each his own. I will believe the 7.62x 39 is accurate when you are punching 1 inch 5 shot groups at 300 yards. Then I will recant my statement.

Saying the 7.62x39 is like a ppc is a bit of a strech. I know they 7.62x39 is the parent case for the 220 russian and the 6mm ppc is based on the 220 russian. They arent shaped anything alike the only thing they really share in common is the the base of the cartridge. Don't get me wrong the 7.62x39 is a great round for a battle rifle it just isn't something I would chamber in a target rifle.

99.8% of 308's won't do that, does that mean 308win is an inaccurate round?

I wouldnt say the 308 in an inaccurate round but I wouldn't call it a target round either. The main reason it is used as much as it is there are target matches that require it or a military round. Like I said if you build your gun and can maintain less than half MOA accuracy I will recant my statement about the 7.62x39.

I tend to agree this line of thought. After the bullet is in the bore of the rifle, why in the world would the shape of the case have anything to do with it.

handloaded match grade 7.62x39 vs handloaded match grade .308..... i doubt there would be much if any difference.

Now I am a total ignoramus so dont trust my opinion farther than you can throw it, but I am guessing the LAST 4 inches of barrel matter a lot more than the shape of the case in the first 4 inches.

with ammunition handloaded to the highest degree of precision shooting the most precise projectiles 7.62x39 is just as likely to be a 1/2 MOA shooter as ANYTHING else. When that 110grn berger bullet leaves that shilen select match bbl it will have no memory whatsoever of what was stamped on the case head.

krochus, will you be using a .310 or .308 bore? I admire your guts to give x39 a whirl in a match rifle. My concern is the lack of quality bullets. The Hornady V-Max is about as good as they get, from my searchings.

Freakin' awesome.

That's a bolt handle. I'd try to put a skull on mine, though...

.308 bore 1-15" twist

1-15" twist?? Isn't that a little slow?

Just curious, and looking for edumacashun...

A 1-15" twist should stabilize bullets up to 150grs, I'll primarily be shooting 110 to 130grn bullets, I would have gone with the slower twist 1-17" rate recommended for this bullet weight range but at the somewhat slower velocities of the x39 I wanted to insure a good stability factor and not be on the "ragged edge".

the reason behind using the slowest twist I can get by with is to achieve the highest velocities possible with the least pressure.

That's not a bolt knob. It's a space station.
