[QUOTE="Bart B, post: 103436, member: 5302"] Mr. Browning, I applaud you for noticing that southpaws get a different windage zero than northpaws (right handed) people. And also for being able to figure out the reason is because the barrel moves sideways in different directions before the bullet exits. I'm convinced that fewer than 1% of the rifle shooters on this planet understand this. One group of people in that 1% group are those who regulate double rifles so both barrels shoot bullets to the same point of aim. They do this by aligning the barrels parallel then putting a wedge between them at some mid point then clamping the muzzles together so their axes cross at some downrange point. That point is closer than the zeroing range. Which means a bullet from a .500 Nitro Express' left barrel goes straight down the barrel for several inches then turns right while really heavy recoil moves the rifle back and towards the left and when the left muzzle axis finally points at the point aimed at the bullet exits when the sights are aligned left of the target. Bullets from the right barrel make a left turn before exiting. So if someone very distraught says their $30,000 Holland and Holland .500 Nitro Express double has both barrels bent inwards at the middle and wants them replaced, you should calm them down and say "they're supposed to be bent that way." If one's a good enough shot to sight in a rifle standing on their hind legs using only two rounds, they may notice that the windage setting they end up with will be different than what's needed to zero from the traditional 'rifle on bags atop a bench' method.
