I was wandering if anyone knows if there is anydifference in the blue tipped v-max bullets and the red? I purchased a box of fiocchi extrema 223 bullets loaded with 40 grain v-max bullets in blue. They shot great out of my m77(.5"). So i purchased hornadys 40 grain v-max bullets with the red tip and loaded up 100 rounds with varying lengths right around the coal that was reccomended for these. Best i got was 1.25". After talking to my local gun smith he said that usually when a gun will only shoot a specific bullet it is most likely a crown issue and i may end up having to shoot a flat base bullet. So im trying to find out if the blue tipped v-max could have possibly been flat based. The place i purchased them no longer carrys them and i can't find them to pull a bullet to check. Thanks, Nick.
