[QUOTE="dfanonymous, post: 1934435, member: 97050"] True velocity in supersonic. True BC in trans and sub. It’s not about if the Labrador is right or wrong. It’s about aligning the numbers. There’s various reasons for this, a lot of it has to do with including human error into the number. Which I’m assuming is the case since bullets don’t group better at 800y then at the 100. Even if one tried to blame it on a stability issue, it’s illogical to think that a bullet would be erratic at 100 then course correct itself at 800 perfectly. The BC shouldn’t be that low and when you go to shoot further, or even maybe closer, it will be off. Further more, the relevance of BC, to include g1vs g7 vs CC is for the most part (assuming you’re using manufacture recommendations) isn’t worth arguing about until you reach trans and sub. This is where you start seeing significant differences in data. If you’re firing anything past a .5 BC at 3000 fps you’re not even close to to trans at 800. Even if you’re at sea level in a Chicago blizzard. [/QUOTE]
