First of all sight your gun in at 25yds. Then depending on rifle and ammo you can work from there. Here is a link to one of many ballistic tables. Notice TRAJECTORY table for each bullet type.

I’d say you need to goto a range and shoot at 100 yards and even the gun out, then you just need to look at the ballistic chart for the ammo your using to see how your going to sight in the rifle and the calculations you need to make it shoot to the distance your looking for, since it really depends on how far your shooting on average.
since you didn’t tell us the ammo your using, just the name of the cartridge(. 223 Remington), we really can’t help you any farther then that, different brands, bullet weights, even powder choices can effect a gun’s performance with a particular caliber.
You have just learned one of the interesting facts about the diminutive bullet that the . 223 fires. 450 yards is way too far to expect accuracy and performance. I spoke with a professional guide recently from Wyoming. He suggests to his clients that they never take a shot beyond 200 yards, regardless of caliber.
I’m with Al on this you do need a ballistics table to determine what the drop would be for the intended distance. Having said that lets start in the beginning here shall we?
#1 You need to figure out just what range you are going to zero your rifle to. . 450 yds is not the proper one to start at.
#2. You need some range time shooting for zero to practice your accuracy.
#3. A 450 yds shot is difficult at best even for experienced shooters. You need to look up what your optimum PBR is for the caliber, bullet manufacturer. There is a whole slew of pertinent info you would need if your looking for the best accuracy you can get. Not the least would come from chronographs for muzzle velocity (average since no 2 loads exactly match although you can come so close it won’t matter much).
Please understand I’m not trying to give you a hard time. I’m just saying you need to do some homework. The little bit of info I gave was just a suggestion and there is a bunch more variables. It all depends on just how accurate you want to be and weather or not you really need squeeze as much accuracy as you can from your firearm.
Good luck to you.
at 100 yds its 1/8 of an inch
at 200 yds its 1/4 of an inch
at 300 yds its 1/2 of an inch
at 400 yds its 3/4 of an inch
at 500 yds its 1 inch
