Home Forums Hunting & Shooting Long Range Hunting Rifle Cant

Something like that! Haha

An informed long-range rifleman will tell his gun builder to make sure and clock that barrel up dead nuts at 12:00. A good long-range gun builder will answer with way ahead of ya partner.

So, with a little practice it seems canting the rifle into the wind could allow holding on the target and letting the amount of cant to handle windage.

Then that would screw with the elevation.

The windage does not change with distance unless you adjust the scope to center at some distance. If the scope is offset 1/4" (one quarter inch) to the left, and the rifle is sighted to hit center at 100 yd, it will hit two and a quarter inches right at 1000. If the rifle is sighted to hit center at 1000 yds, it will never be more the 1/4" off at any range under 1000 yds (ignoring the effect of wind and mirage, of course). If the rifle is sighted to hit 1/4 inch left at 100, it will be 1/4 inch left from zero to infinity. The higher the scope is mounted, the more offset will result from the same amount of cant. With adjustable stocks, cant can be minimized for any position. If you can't use an adjustable stock (rules etc.) you make the stock to work in one position, and adjust your body for the rest! GD

Good summary, however spin drift prevents the above 1000 yard sight zero scenario from working as described if you are referring to actual point of impacts. If you are only referring to line of sight your description is correct.

Yes. I ignored ,wind, mirage, spin drift, gyroscopic precession, and direction of the shot. In truth, any time I have turn an "X" into an eight, it was because I missed a wind change. I could never fins anything else to blame. GD

True that on the wind! I do treat spin drift as a constant in relation to impact whereas all of the others are variable. At those all too rare times when I have a perfect 1000 yard no wind zero, I would then shoot at 500 yards and see a consistent POI 1/2 MOA left which centers the group on the left X ring line and asking for 9s or worse. I had to ask one of our top national shooters why that was and then the light bulb turned on...of course he additionally said "that's what sighters are for."

Or, said another way, unless the windage component of the POI is set to exactly match the bore offset (not the scope offset) at some distance downrange, windage will change with distance.

Yes it can

Well played Bb, well played.
