Sighting in: point blank range?

I have read a little on sighting in using a method called point blank range or something of that sort. My question is what is this and how do you do it and why is it better then just sighting in at the average yardage you will be shooting at? Thanks for the info,

Sorry Should have put this in the firearms and reloading section. If someone could move it I would be greatly appreciated. /ubbthreads/images/graemlins/laugh.gif

I've set up my .223 using a point blank range type scenario. I am using Remington V-max factory loads and considering I want to hit a 3" vital zone. I have my gun sighted at 1.25" high at 100 yards. This gives me a zero of 195 yards and a "point blank" range of about 225 yards. That is, I can hold dead on for anything from 100 to 225 yards and expect to hit within that 3" zone (if I do my part).

Hope this helps.
 
Bill pretty much covered it. By "point blank" it means that anything under the "point blank" range you don't have to "hold off" high or low. You just aim at the center of the kill zone and your bullet will hit a little high or low, but not more than the size of the kill zone. He uses almost the exact point blank sighting for his .223 that I do. I'm sighted in at 1.25 inches high at 100 yds which gives me a point blank range for coyotes at about 225 yds. I mostly shoot the 52 gr. MHP or the 50 gr. TNT. your bullets velocity and ballistics coeficient will of course affect this tradjectory. The size of the kill zone of your quarry will also determine what your point blank range is. Anything further away than your point blank range you will have to hold over accordingly.
 
What Bill said is true, but is seems to me that the accuracy of your rig has to be taken into account. Shouldn't the vital zone be considered smaller, depending on your average group size..........?? Sometimes I think about this stuff too much and confuse myself. Anyone else have thoughts about this?
 
I never sight in my calling rifles that way, 1 1/2" high at a 100 will make you miss a small target many times. I'd rather my calling rifles be dead on at a 100. Many times my shots are in the 25-200 yard range with only a head to shoot at thru a small hole in the brush. I didn't always remember to hold a little low and ended up burning the hair off the top of their head and nothing else. Now I generally hit them between their eyes. If I get a long shot I can use the top of the bottom duplex where it comes to a point as a aiming point. Or you can just lay the cross hair on top of his back if he's not too far. It takes a little time, and a few shots, to figure out what is best for you, and your situation. I encourage you to shoot your rifle at 10, 25, 50, 75, and many other ranges, because you will never know what range the next predator will be, maybe 2 feet! My .223 is only 3" low at 200, 12" at 300.
