ok i have a m41k on a 16in bushy i usually run UMC 55gr thru it and it does fine i bought some EBR subsonic ammo and most of it went super however there were about 5 or 6 in a row that went totally subsonic.... it seemed that these started to go sub when the can got hot... is this related? i wouldnt think this would have anything to do with how fast the bullet is traveling but it has got me wondering... im trying to get some ammo that goes sub every time.... i know the ballistics arent that good but i dont care anbody kno where i can get my hands on some? dont say TTI armory ... they are sold out forever |

Just a wild guess ,,the barrel got hot = less friction = less pressure build up of the burning powder =less velocity Just like to little crimp on a cartridge can LOVER the velocity ,because the powder dosnt get up to right pressure for optimal burning but normally you get higher velocity because of the hot chamber  To many variables to say for sure How much did you have to pay pr ,round

man it was something ridiculous over 1$ per rd |

Or just get a Ciener kit and shoot .22s. You end up with about the same result downrange: a .22 caliber bullet traveling around 1000 fps. And the gun cycles just fine, while keeping your ammo subsonic. Sure the subsonic .223 is a little heavier, but if you're concerned with weight, shoot the 60 gr. Aguila SSS. |
