Re: zastava m57/ tokarev 7.62x25
Josh, First welcome to the forum, there is lots of nice knowledgeable people here. Most right handed shooters tend to shoot low and left from natural pull of the trigger. I would first get used to the gun and make sure your trigger pull is smooth etc.
After all that my ( like new ) M57 was still shooting left so I took a brass punch and drifted the rear sight to the right a tiny bit and on first try got it to shoot dead on center. As far a shooting low some of that seemed to change after I started hitting center but it also is something you need to adjust your front sight bead from low to high depending on the range to the target. Every gun will be a little different, as my P64 shoots low at about 15 yards so I raise the front sight a little in the rear notch to compensate.
Have fun, the M57 Tok is still one of my favorites, as far as the brand of ammo I have not noticed much difference in POI with any except some poor quality, inconsistant old corrosive stuff.
let us know how it works out after a bit more shooting. By the way my rear sight ended up a little off center to the right to be dead on.
