Sighting in

[shoota]

Gents,

So went to the range over the weekend to sight in my rifle, got a new scope on it so needed to sight in for this years hunting. First off only had access to the short range on the weekend so max shooting was < 60 yards which kinda of sucked cause I wanted to see what I was shooting like at 100 yards.

Here goes....
Rifle was bore sighted set a target up at 25 yards, 1st shot was on paper, adjusted and on the 3rd shot I was dead centre bulls eye at 25yards.

pushed the target back to see what it would do at 50 yards. 2 shots at 50yards and both shots were side by side 2 mm away from going through the same hole however were 1.5 inches high at 50. I am wondering if that is too high??? what kind of height should I expect at 100 yards, I guess the only way to find out is to shoot at 100 next weekend however it has been bugging me since I got home. I read a bunch of stuff online but I would like to know what the experts think.

I thought that sight in at 25 you would be about dead on at 100, but the 1.5 inches at 50 is bothering me, at what point is it reaching it's arc?


oh yeah and as for ammo it's .30-06 Federal Blue Box Power Shok 180 grain soft point.

gun is tikka t3 lite stainless topped with a bushnell 3200 3X9X40, did I mention this thing shoots like a fawking lazer beam

Bear in mind your crosshair is about 1.5 inches above your bore and your bullet is coming up from there to print a zero at 100, if that's what your hoping to zero at. You will need to shoot again at 100 for sure, but I think you'll be pretty good getting on target.

With a 30/06 loaded with 180 gr spitzer bullet at 2700ish, a 50 yard zero should give you roughly a 200-225 yard zero, but this depends on how high your scope is mounted above the bore of your rifle. An inch and a half high at 50 is a bit much for normal hunting ranges IMHO. The best idea is to get out and shoot at ranges that are compatable with your hunting conditions. When shooting at longer ranges it could be that you will see a windage error that you were unaware of at close range.

Here is something that can help you out with determining bullet trajectory. It is from the Norma Ammunition website. If you have some basic info like ballistic coefficient of the bullet and muzzle velocity, you can get a pretty good idea of the flight path of your bullet at any distance out to most practical ranges.
Here is a link . Give it a go.
