Improving Accuracy and Reliability

    Well, my Centurion 99 G3, which used to go bang absolutely every single time with the right ammo, doesn't always dent the primers. I've tried cleaning and lubricating the trigger group, doesn't seem to help. Some of the ammo is a little dirty, and I thought maybe it gave so much resistance loading that the bolt didn't close completely, in which case I'm darn glad the pin didn't hit the primer. Well all the dirty Chilean 7,62mm Cartuchos de Guerra are gone, and now I only have European stuff with shiny cases, so maybe it'll clear up. If not, would it need a new firing pin spring?

    And now about accuracy: My groups have been expanding, not shrinking. Probably just me getting tired and impatiently forgetting to let the barrel cool for a minute or two, but are there any ways to specifically improve the G3's accuracy? Specific handloads? I use Winchester match, a Tasco 3-9x40mm, and a sandbag. It once gave me roughly 1moa. I'd like to do better. Of course I'm probably the part of the equation that needs the most improvement.

    Do you clean the barrel after every shooting session ? Clean it till no more blue / green copper stains appear on the patch ?

    Never gotten blue/green copper stains. I do generally clean it after every use.

    Do you use a copper remover bore cleaner ?

    Is something loose , messing up accuracy ? Like the hand guard or handguard screw ?

    Which cleaners are specifically for copper? And yes, the handguard is loose. Any ideas of how to fix it?

    Only thing I know to tighten the HG is tighten the screw ? :-(

    Hoppies # 9 is a mild copper cleaner ( takes a long time ) .

    All of the ones that smell of ammonia should disolve copper . I use Shooters Choice copper remover . ( Also kills corrosive salts . )

    Follow directions , this stuff is aggressive .

    Tighten the screw? What screw? All I have is a pin.

    I would be happy with 1 MOA out of a G3 look-alike or even a real G3/HK 91 for that matter. Remember, these are battle rifles not sniper rifles. The accuracy standard for even the M-16 is only about 3 MOA I believe... For European models like the G3 it is in the same ballpark...

    My experience is with a CETME & it has a HG screw . If yours is a G3 or different , then I do not know .

    Best of luck .

    By the way , my CETME may have a chrome lined barrel , it seems easy to clean & very little copper fouling .
