Hey Guys,
New to the forum, GREAT place. I just picked up a really nice WASR 10/63 that is actually straight and built very well (no twisted receiver or trunnions out of square). I have a question concerning the rifling: I'm seeing conventional 4 groove rifling with good depth and sharp edges...not worn or anything, but each land has a smaller land that runs along with it....it's really hard to explain without pics but it's as if each land is divided into two lands, but not evenly divided. The rifling will spin the hell out of a bore brush and a patch and the barrel easily passes the "bullet test" but it's just something I've never seen before. using caveman illustration tech, each land looks like this: ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ Where a normal land would look like this: ________________________________________________________________ ________________________________________________________________ Can anyone help me to possibly identify this anomaly??? I'm really curious if anyone here has this same thing going on or it's some sort of defect. Thanks in advance and looking forward to any and all replies. |

Quoted:
Sounds like the rifle was rifled with a worn cutter. Is the bore chromed? BSW Yeah, it is chromed. I thought too that maybe the button or cutter that was used to rifle this barrel had maybe worn funny from service. But it's so symmetrical and even that it looks intentional. The barrel and trunnion are dated 1965 so it's an oldie......and has been shot..... most likely when it was a full auto service weapon. Like I said, the rifling is very sharp and very deep, and even a slightly snug patch will twist the cleaning rod like no tomorrow. I'm not worried about any accuracy loss or anything, just really curious. I'm gonna try to take a pic tomorrow and post it up just to throw it out there for curiosities' sake.....and hope that someone has seen something like it. Thanks for the reply. Jay |

I wouldn't worry about it. Variations in rifling are normal. As long as they are all spiraling the projectile at the same rate it shouldn't have a detrimental effect on accuracy. You say they are nice deep crisp lands and grooves and the bullet test is good. Should be fine. |
