    . . . and where is the bullet that caused all the commotion while all this is going on?


    Long on its way to meet the target.

    There is quite a bit to this.

    I skimmed over the posts and agree with the fact that the bullet leaves the barrel before the recoil forces act on the barrel and the shooter. The issue with flexing, and barrel oscillation, is more an issue for full-auto firing. A semi-auto target shooting situation will never have to deal with that.

    Now, the issue of stiffening the receiver would help to reinforce a build to make it overall more sturdy, but should not affect accuracy.

    The issue of accuracy on an AK is mostly to do with ammo quality *AND* barrel quality. The chamber of an AK is *very* loose, up to about .008" larger in some cases, making for a very reliable gun that doesn't foul up due to a dirty chamber, no matter how much you don't clean it. Sound familiar?

    IF you were to cut your own chamber and load your own ammo you would see much tighter and consistent accuracy out of it. The problem with 7.62x39 is that it is an "intermediate" round that doesn't have that good of long-range performance. Has been roughly compared to a .30-30 in ballistics. Thus the longer range calibers are preferred for an "accuracy AK" build.

    Hope this helps...

    DAMN!!! thats very cool. i love it when the purist scoff at the unwashed, then get their asses handed to'em. i have this underdog complex.

    i see shit like this at the range all the time. some dude shows up with a bolt gun all tricked out with more $ in a bench rest than i have in my ak. clamps the rifle in and literally stares at the magazine in his hand for 5 minutes wondering how he's going to get it in the rifle. my 14 y/o kid had to tell him to take the gun out of the vise.

    biggun, didnt even get as far as looking at the case diameter on the x54 vs the others. this is still a vaporware idea until i get the kit in hand.

    Here's a slow motion clip of the AK.
    I can see barrel flexing going on.
    The large bolt also racks the entire rifle.
    Yes there is some barrel flex, but that also happens with an AR shooting a smaller round, also a lot of that racking the entire rifle is hard to tell since most of the shooters are holding it loose.
    Here's a video of a milled AK, still has some barrel flex




    Smartbomb, a Yugo with a rough bore is my worse shooter, I'd say it's about 5-6" grouping with open sights at 100 yards. The rest will hit a clay bird out to 200 yards if I take my time and can keep focused on it, at that distance I sometimes have trouble keeping that size target and sights in focus at the same time.

    Rim diameter 14.40 mm (0.567 in)
    Go to Wiki and do a search on the different rounds, most have that info on there if you don't have a reloading book.

    The chambering reamers and sizing dies for any of the 6.5x54 variants will have to be custom made. That's why I went to the 6.5x54 Mannlicher instead - and it's available in both rimmed and rimless variants.
