open sights

[huntingfool7]

I didn't draw it, I stole it off the internet. Take the line of sight that is drawn out if you want.. Follow the bore! Look down the bore. Look across the top of the bore. The illustration may not be perfect, but it does show the arc of the bullet trajectory with reference to the rifle bore. That simple!

Like many things found on the internet, it is inaccurate.  If you take the sight plane out of the drawing you can not have the bullet trajectory impact at 100 and 400 yards (and be on at both ranges).

Further if you take the line of sight out of the equation, the only place that the bullet is in line with the barrel is directly in front of the barrel.  The bullet will impact low at 100 yards then continue to drop from there.  Ending about 24" low. 
The higher your sights are above the bore, the flatter shooting your rifle will appear on dropping chart.

I am very comfortable with admitting when I make a mistake.  I view that as a personal positive trait.

I notice in your post #5 you state "If you sight (iron sights) in at 100yds to be zero, then your bullet point of impact beyond 100yds will be below target.

I wonder if we're viewing different parts of this thread.  Post #5 is an accurate statement.  I have been looking at and referencing the posted trajectory chart that shows the bullet impacting dead on both at 100 and 400 yards.  Don't know what cartridge that refers to but it's not an 30-06

None of what I list here is 'dead on at 400yds' if sighted in to be zero'd at 100. It is 30 some inches low at 400yds. I don' t know what optical illusion you're seeing.
 
Fine! I've removed the graphic if it is too confusing.  What I liked about the graphic is that it depicted the angle of the bore relative to getting the bullet path enitial arc to zero at 100yds.  Your visual sight plane does impact or pass through the arc two times.  This isn't rocket science..  And it ain't my first rodeo.
 
The OP has stated that he'll just sight in at 200yds..  Lets leave it at that.

Not confused at all...however I am very sorry to have offended you.  Best wishes and I hope you have a Merry Christmas.

jackofalltrades  thank you for the picture. like i said i will sight it in at 200 and i should be good up to 300 yards if i see were it shoots. now just to wail til it stops snowing so i can sight it in. thank you everyone and merry christmas

 :)But don't forget that once you are sighted in, if you shoot your rifle upsidedown the bullet won't fly as far.

Happy Ho Ho and Merry New Year!

Bo, That is a funny thought.  If said gun is sighted in to hit dead on at 100 yards then was turned upside down.  The bullet would cross the line of sight (between 17 and 21 yards) and continue to drop.  The bullet would only cross the line of sight once in that case hitting low at 100 yards.

Is that also the case if the shooter and target are upside down too? Or just the rifle?  what if the shooter is upside down with a right side up rifle shooting a sideways and inside out target?

  The shooter really should be perpendicular to the rate of the bifelinial complex of drop of the cortex( X )the rate of contour of the ogive. other than compromising the factor of the grooves enhancing the HP expansion factor the equation is straightforward.
In other words never look thru a right handed optical device left eyed which of course cannot be done with open sights and always consider the axis of the earth and direction of orbit. ( hint the sun rises? in the East.)
