You didn't say how far you're comfortable shooting. With that gun and that ammo, I would follow James B's suggestion and sight it in at 1.5" high at 100 yds. As soon as you have time, set some targets up at 50, 100, 150, and 200 to see what your bullets are doing. Getting more familiar with your rifle and loads is always a good thing. Find the ammo that groups the best at 100 yds. and go from there.

Troutman10: I recommend you sight your .30-06 to be 2" high at 100 yards. This will make you sighted right on at about 200 yards and maybe 7" low at 300 yards, depending on the bullet weight you use. Use some of the freely available ballistics programs to get more detailed information. The idea is that over a decent range window you simply aim at the center of the vitals area and shoot, making no adjustment for your distance from the target in relation to your sight-in range and your cartridges peculiar ballistics. If you strike your target 3" above the center of the vitals or 3" below the center of the vitals this will still be a killing shot. Probably 7" below the center of the vitals on a deer is still a killing shot, though it may be getting dicey.

I just checked an exemplary commercial loading. A Federal cartridge loaded with a 150 Grain Sierra Game King bullet sighted in for 200 yards is 1.7" high at 100 yards and 7.6" low at 300 yards. If you were 2" high at 100 yards with this load you would be dead on just beyond 200 yards and a little less than 7.6" low at 300 yards. Different bullets/cartridges will result in somewhat different ballistics, but maybe not too far off of this general set of numbers.

In special cases a different sight-in may be preferable. For example, for elk hunting I sighted my .30-06 shooting 180 grain bullets to be 3" high at 100 yards. Elk have larger vitals areas than deer do, and I think this adjustment made sense for an elk hunt.

ORIGINAL: Troutman10

I was wondering if anyone knew a website that could help me out with my 30.06 (or if anyone here can supply me with info instead of a website). I'm going to be shooting 150 gr. shells out of it and didn't know what to expect for ballistics. I've sighted it in for 100 yards and it's right on. It's about an inch or two low at 40-50 yards as well. I would like to use it to its full potential just in case I had to make a longer shot than 100 yards. Any help would be appreciated.
I zero my .270-.30/'06 class rifles to hit 4" high at 100 yards. This puts them about +4" at 200 yards also, -3" @ 300, and about -15" at 400 yards.... This is with 150-grain bullets at a MV in the 2900 FPS range for both cartridges. This gives a max "point-blank" range for deer hunting of around 330 yards, but greater for elk or moose. A mid-range height of 4.5" will not cause midrange misses on deer, but anything greater might......

They only way for sure to know what it's going to do at longer distances is to actually shoot it at those distances. Don't assume anything.

Ifor one only use the "ballistic charts" as a general guide. There are just to many variables in the equation. You can have all the charts and web chair quarterbacks say this and that but untilYOU ACTUALLY GO OUT AND SHOOT THE PARTICULAR LOAD IN YOUR GUN it's all guess work.

Case in point......... you said the rifle is shooting right on at 100 yards but an inch or two at 40-50 yards. Well it didnt take long for folks to chime in and say that it's not supposed to be> I have no doubt you are being honest so whjat gives? Real world experince or something a chart says.

I am in no way trying to demean anyone here it's just that over many years of shooting my experinces tell me to shoot loads at various distances to tell what really happens, besides it's great practice to do so. Not saying that anyone here would do it but there are some that have never shot over 100 yds and then have no problem when hunting taking shots they shouldnt have.

Well, sorry for my rambling on.....
Agreed

Excellent rambling Double A!

Ballistic link for you to get a guideline. Need to input data such as Muzzle Velocity, Bullet - style & weight, BC- Ballistic Coeffecient,sight in range, sight height (scope - 1.5" is common unless using high rings or see thrus) Max range, Intervals of data (ie 50 yards to 300 will give you ballistics on 0(muzzle), 50, 100, 150, 200, 250 & 300) then calculate.

You can get the FPS from the manufacturer then subtract -150 FPS for MV due to the 22" barrel. BC should also be found on the manufacturer's website in the ballistics for the bullet.

Any way just a guideline but may help you.
