Let's answer Aussie's post above: ballistically speaking, how much gain would he get going 280AI over a 280? Are we talking a 1/2" at 300 yards, 1" at 600 yard, etc?
Read his parameters...
I'm not being a smart ass, I would like to know myself. I've thought about and looked at many tables, but it's all different...and I don't have one to comment about. I have pondered it a bit myself though.
If 270's are "gay", then its the wierd uncle that plucks his eyebrows. 140 TTSX at 3,100 is about 1" less drop / 1.7" less drift than a 130TTSX doing the same speed in a 270. At 500 yards.
