Truth be told, it could still be done but it would have been better to have used a representative ammo from one of the same lots used for the other testing. View Quote I agree but I would put money on the results being different enough to be interesting. Like I said i wouldnt be appropriate for a laboratory white glove test but I would be happy with the results either way. The only gun I ever had a issue with Wolf was my AR10 carbine with a stainless barrel. Broke the extractor but that was years ago. When I get it back together I might try it again with where 308 has gone |

I suspect the steel in the projectile had an effect when the barrel got over 700 degrees and the steel in the barrel started getting a bit plastic.
I suspect it 'engraved back' a bit. That said, I agree with what you are inferring about the fast-burning powder being another factor. |

So the damage was less to do with the ammo and more to do with the ammo in very hot barrels? That makes sense, I guess there's not any issues for normal use. I don't know much to nothing about such things so wading through the masses of information and telling true from false and relevant from irrelevant isn't very easy. Thanks for the clarification

|
I have a lightweight Colt 1/7 CMV barrel with around 12K in it, at least half is 62 gran Barnul steel jacket. The bore erosion gauge is still well short of the reject for deployment mark. This is my main training and practice rifle so it gets used hard but not abused.
The control should be the same model Bushmaster lucky gunner used and the ammo should exclusively be one type of steel jacketed ammo. |
|
I am going to say, based on memory of last fall when I gauged it that the gauge went in a bit over a half inch.

can someone who has gotten this stuff confirm whether it's boxer or berdan primed?

Thanks for the clarification The problem is without a control we will never know Hard chrome is harder than steel, hard chrome is also performs less than ideally under high heat applications, I honestly believe that under normal shooting conditions the barrels in that test would have held up much better than they did, but due to the intense heat, and steel jackets the chrome lining began flaking off until the steel was exposed. |

The hot barrels definitely helped speed up the process, but I think the 'relative wear' issues will still be there. |
|
I think relative is the wrong term. I think of you were to do a proper graph temp vs rounds fired vs wear, you would see a slight increase over copper up to a certain temp and then the steel would go and jump asymptotic before the copper. Stay below that point and there will be a difference but it will be something more like 15 or 20% and not 50+% more wear.
With the temps they are running, they are softening the steel plastically. Softer steel has less problem engraving copper than other steel and that, and the slower burning powder, explains the Federal results. |
|
After all, do we hear much about chromed eastern bloc commie caliber barrels wearing out prematurely?

Wouldn't a better idea of the wear imposed by the Wolf FMJ ammo be had from looking at 7.62x51, instead of 5.56x45? I think most US military 7.62 M80 Ball produced for machine gun use over the last couple decades, has been with gilding metal clad steel jackets. |

Though I'm not an engineer, HeavyMetal's argument makes sense to me, intuitively. Why wouldn't hard, cold steel bullet jackets do quite a bit of engraving on hot, soft steel barrel rifling?
I would, however, argue that we never hear of "commie" AK47 barrels being shot out by steel-jacketed bullets because I'm guessing that most foreign users can't afford the volumes of ammo that American shooters can. And even if they did, I don't think they're interested in doing controlled tests and reporting their results from, oh, the Central African Republic. |

Yesterday Alexander Arms got in a boatload, literally, of their new 6.5 Grendel magazines from Elander. These are coated steel (withstand 96 hours salt spray), and are designed from the ground up to be dedicated 6.5 Grendel magazines, with both the curvature and rib placement specific to the 6.5 Grendel.
Should be the best 6.5 Grendel magazines yet. |

If the Russians start building 6.5G AK's it'll grow like wildfire. The performance of the 6.5G obviously stomps the 7.65x39, which will become apparent pretty quickly to not only the Russian masses but other nations looking for better weapons. All that is needed is ammo which could be supplied in the numbers needed should the facilities be allocated. While I'm a fan of the M16/M4, the US and other 5.56 using nations would be at a distinct disadvantage when fighting rifle to rifle with 5.56 vs 6.5G. Not saying that would ever happen but the Russians have already found a love of the 6.5G and are making the ammo so it will just take time for more people to realize how much better the 6.5G performs compared to what they have now.

I haven't seen it anywhere else, but there might be a little problem with getting any Russian AKs, let alone ones in 6.5. I hope it doesn't grow into restrictions on ammo too.

Interesting, makes sense, I wouldn't be surprised if they went that route for a main caliber. Personally I've really become a fan of the 6.5Grendel performance, I'm far from an expert but it seems like it would make a fantastic caliber for the AK or its predecessor or even better as the US's next caliber AR. Although I'm sure there's WAY more likelihood that the Russians do it. |

I sure "HOPE" Hornady starts to produce their version of the Grendel steel case ammo like their "Steel Case Match" now that there will be steel cases available. I know it may be a long shot but we can all HOPE.

Assuming a half-way point in cost between steel cased 5.56 and steel 7.62, I'm guesstimating a per box cost of about $7-8.00 once the market
stabilizes. Given the ballistics of this round and the weight of carbines for it versus the .308 GII I had been considering, the 6.5 becomes very attractive. So what would be the easiest way to put together a 16 inch midlength carbine with a pinned FSB?

None of that matters a hoot if the stuff doesn't actually show up on the market. With everything going on with Russia, if Wolf doesn't get it here soon in quantity, we'll probably never have a chance to really give it a chance.

If there's a demonstrated market, they'll figure out how to get it here. .gov can't even nail down our OWN tax cheats, I don't suppose a little corporate slight of hand on the far side of the ocean would be any easier.
