I have never had to, but if one was shooting uphill (30' below target) at say 200yards, would you need to aim high or low?
I'm shooting 140 gr Remington Core lok in a 30/30 cal.
What about downhill?

HOW LOW?
Is there a website that I can find this on?

Can't help you there, maybe James will come on, he's pretty good at that. I have almost 0 trigger time behind a 30-30.

At the ranges most people use the 30-30 I wouldn't worry about it. You'll not see the major differences until you've reached a little further out.

Thats wrong, shooting up hill you will have less drop and shooting down hill you will have more drop.

I disagree.
There's no more "drop" in a bullet shot up hill
or down hill than there is from one shot from a
level position.
"Drop" is determined by gravity, which is equal in
all cases here on earth. Now, depending on the angle
you shoot from it's possible you'll want to hit the
animal higher or lower so that the path of the bullet
beginnig with the entrance tears thru the appropriate
vital area i.e. a little higher shooting from steep
uphill positin, little lower from a steep downhill
position but again, unless these angles are STEEP and/or
fairly long range it's not too much to be concerned
with. This is my opinion.

I misread the post  , If your just shoot up or down hill 30 feet then there isn't going to be enough to worry about. A 30-30 sighted in @100 yds. is going to have somewhere around 7 inches of drop @ 200yds. But if you were shooting at a 45 degree angle @ 200yds. there is enough to make a differences.

PK, I disagree shooting at a 45 degree angle up hill a bullet will have half as much drop as one shoot level because it is going away from the force of the gravity. And shooting down at a 45 degree angle it will double in drop because it is being lanched toward the force of gravity.

The correct answer is to hold lower than normal when shooting steeply up or down hill at long range. (At gentle angles you can ignore the problem altogether over the maximum point blank ranges of hunting rifle cartridges.) http://www.chuckhawks.com/shooting_uphill.htm

Using the numbers from the preivious post
(7" drop at 200 yds) this would give a shot
fired up at 45 degree angle a drop of 3.5"
and one shot down at 45 degree angle a 14" drop
unless I'm missing something (and I admit I could be).
This is WAY off from other posts stating the need to
aim 1" low in all angle cases (which seems negligable
to me).
And HWY_MAN, MGD???
How much cheaper can you get?

There is no question that firing at extreme angles will cause bullets to impact higher than they would perpendicular to the earth. To disagree spits in the face of physics.

After read that link it looks like i'm wrong  . I guess I better go back and read up on this I thought I had it figured out.

So professors, what's the equation? There's some dead/digested deer that are un-dieing to know. PK

Have you ever read a loading manual or any material dealing with ballistics? Google is your friend...but I'll look it up to appease the un-dieing.

Lyman 48th Edition, page 107, paragraph 5:
"The distance a bullet travels in relation to the earth's center, or gravitational pull, from the muzzle to the target is what determines how far a bullet will drop in a given time span. With a steep up or down angle, he distance to the target will be longer than the distance the bullet travels in relation to the earth's center. Rather than dropping the amount we expect for the distance traveled to the target, the bullet actually will drop for the distance it travels in relation to the earth's center. The steeper the angle, the shorter that distance becomes."

So, the distance that the bullet travels
in relation to good old terra firma, not the angle
at which it is shot, determines the drop?

Basically...
I've seen a lot of rangefinders lately that do the math for you. They calculate the actual range, then subtract "X" based on the angles.
There is a formula you could use, but it would be very complicated. Certainly more than this country boy could figure out on the fly. But it really is not much of a factor (for rifles) unless you start talking about long distances or extreme angles.
Or, it makes a big difference when you are bowhunting from an elevated postition. Even a shot from 25-30 yards could sail completely over the back of Mr. Big Rack if the angle-to-target is not taken into account.

OK, how's this: I was wroooooo... I was wroooooo... OK, I made a misttttttt.... Alright, tell me this, how low do I need to start aiming? One inch in all cases seems a bit static for the many variables. OK, I may not have been exactly correct. THERE WORLD WIDE WEB, ARE YOU HAPPY NOW?? PK
