Thread: Ballistic truing conundrum

It’s an accurate 625yd, measured with 2 different RFs and one i have used multiple times over the years. I range it every time & get the same distance. And never before with various different calibres, rifles, scopes have I encountered the situation where I need LESS dial up by a factor of 10%. In other cases the dial up predicted by ballistic programs is very close to correct or slightly low, ie need to come up 1 or 2 clx.
