I was trying to get more precision for my long range shots with boolits on my cz 308. It has a TR of 1:12, so I loaded with winchester 760 49 grains behind the 311466 boolits, aluminum GC and PC and lubricated with orange magic.
First shot great, second shot 2 inches below the first and third shot 4 inches below the first. 100 meters away.
I was also testing some loads of 311299 and win 760 which were more accurate.
What do you think I could have done wrong?
