Is there a method to zero the ak for a battle sight zero simlar to how an AR is zeroed @ 25M. i am limited to a 25m range. i am running a red dot on a stanag reciever cover mount. (the mount is solid) and my groups are consistant. high speed charts and trajectory tables are welcome but please put a grunt speak caption. thanks |

I've never heard or read anything official on this, but I'd try the M16 improved battlesight zero technique of POA/POI at 25 YARDS (roughly 22.84 meters). With the trajectory of the 7.62x39 I would estimate that this will give you roughly a 200 meter zero. Of course, there is a whole lot of SWAG method in that idea. If you used a parallel zero you could simply follow a ballistic chart from there. Good question, though. |

greentimber do you have a link to any ballistic charts? i havent had much luck finding one. i was thinking the same zero method. that is what i use for my ar's. (rtc350-1) top of the 4cm circle is the aim point and have the rds impact center mass. i wont to use this set up for some 3 gun matches. mostly they have run and gun up close hoser stages but i have seen 8 in plates used @ 100m or hard cover tgts. i dont have muh experience shooting this cartridge past 25m. thanks AATWLG! |

www.remington.com/ammo/ballistics/ballistics.htm just because I like to able able to compare to so many other rounds VELOCITY (ft/sec) Cartridge Type Bullet Muzzle 100 200 300 400 500 123 MC 2365 2060 1780 ENERGY (ft-lbs) Cartridge Type Bullet Muzzle 100 200 300 400 500 123 MC 1527 1159 865 SHORT-RANGE¹ TRAJECTORY* Cartridge Type Bullet 50 100 150 200 250 300 123 MC 0.1 zero -2.2 -6.8 -14.1 -24.5 Also consider that the tables are bullet path, not including the height of whatever sights your gun uses.... |

I've been working on this also, considering these factors (barnual 7.62x39 FMJ ammo) muzzle velocity 2461 fps ballistic coefficient .586 bullet weight 123gr sight height 1.5 inches cross wind 0.0 LOS 0.0 speed 0.00 zero range 27 yard temp 55.2deg f barometric pressure 29.92 humidity 15% altitude 0 feet elevation correction for zero range Ballistics calculator reports that your 25-27 yard zero would be back to about dead-on at 175yards. The above is all simulated and of course the only way to find out it to shoot it but this is the best online calculator I've found so far to play around with. Each rifle and batch of ammo will react differently of course. Blackops_1. |
