Re: Guess what bullet I am Testing ?
I don't have an 18" 260, never got it and the one I used was returned... I DONT" have an 18" 260 I think I would know.
I have SHOT an 18" 260 and it tracks with a 155gr 308 going 3100fps, 8.8 mils to 1000 yards and you don't lose much wind drift, only elevation.
My SHORTEST 260 is 21" ... and it kicks ass, I shot a 3" group at 800 yards with it on video in about an 8MPH wind. No drama going short.
