Aiming point / scope

diver1

I having a crisis of faith ( skill ). When your scope is set for 100 yards. If your target is say 50 to 75yds do you change your aiming point? If it's over 100yds I would hold a little high, dose the converse of that hold true closer aim lower ? I am shooting a Remington 280 which I think shoots flatter than say a 270. Thanks

When I'm shooting lightning bugs at 50 yards I aim 1 inch low but when shooting elephants at 50 yards I hold right on zero. Hope this helps.

Thanks it does, not hunting elephants just Hogs.

Usually no. Look at the distance between your scope and barrel. That is the vertical distance you travel at 100 yards....for hogs this won't really make a difference considering you are using a 280.

I usually set my scopes (on most of my hunting calibers) 2.5" high at 100 yards. Then I am on for big game out to 175-200 yards. You are trying to hit a dinner plate not mosquitos.

the thing is a bullet will travel not in a line but a curve ( imagine a football thrown at the endzone.)

For your 280 I would site in about 2 in high at 100 yards and in that time the bullet will be all over the crosshairs up to 100 yards.

2 in high at 100 yards would keep you good for vital shot 10-150 yards

Go range and shoot one shot at 50, 75, 100, 125 and 150 yards then you'll know where your bullets hit at those ranges.

Yup, I concur. I usually set all my scopes at 100 yards. Anything less then that distance, I still use the center as my point. You have a large enough kill zone on deer and hogs, to not to have to worry about it much. Hope that helps.

At 50-75 yards the bullet will be SLIGHTLY lower, lets say 1/8" inch. This is because the bullet is launched on a BALLISTIC flight while your sight is a straight line.

If you sight your rifle in at 100 yards the bullets flight and your line of sight meet. The bullet "climbs" from the muzzle the distance between your bore and the horizontal cross hair to be "on target" at the 100 yard distance you sighted in for.

For all practical purposes you do not adjust aim points on game until the range gets extreme for the cartridge being used. A deer will never know the difference at 50 to 250 yards with your caliber. If you do your part, don't jerk the trigger, and have a solid cheek weld and good sight picture the 2-1/2 inch difference from 50 to 250 yards still spells a dead deer.

Thanks again for all the comments, they are very helpful.

I sight most of my hunting rifles 2.5" high at 100 yards, That way I can sight point of aim out to about 175 yards, and still hit well within a dinner plate at 200, and with some cartridges 250. Between 0 and 100 yards takes care of its self.
