sighting in question

[lakeshoremunster]

someone told me that if you zero in your rifle in at 25 yards and it will also be on at 100 yards, I dont have a range to test this theory out because the only range i have access to is bills over in circle pines and they have a 50 yard range only, I did site it in at 25 and notice that it shot two to three inches high at 50.

I know my .300 win mags is peatty close to dead on at 25 and also at a 100. But I still check it at 100 too make sure.

Go on the internet and find the bullistics for the brand of ammo your shooting and sight in according to that. It will show you zero @ 100 yrds and your + or - at 50,75,150, ect. I would start their but would also check to give me the confidance to take a longer shot.

This is a somewhat true theory, however the problem lies in the practice of actually shooting the 100 yard (or more) distance. Your sight line is very long in relation to your target distance at 25 yards, and much smaller at 100. It's an ever increasing angle, so any error is magnified over distance, thats why its called minute of angle, it's like radians forming a circle. Its a great practice for starting out if you have not had a firearm boresighted, but don't go out with just sighting and relying on a 25 yard target.

DO NOT take into any consideration where you are at 50 yds. If you you're using the 25yd > 100 yd method. The bullet is typically still rising due to your ballistics.

I run the line for Deer Rifle Sight in every year at my local club. And I see many folks wanting to proceed from 25yd to 50 to 100...

Don't do it otherwise just chalk up another 1/2 box of ammo readjusting everything a 3rd un-needed time.

Now for 200yds, again based on caliber type. If you're 1.5 - 2 inches high at 100 you should be good to go at 200 yd. But again that's rough but it'll get you very close.

there is an old rule of thumb; dead on at 25...dead on at 250. Not always true. I've found with all my calibers that if I'm dead on at 25 I'll be alittle high at 100. 25 is a good starting point to get you on paper after a bore sight and a fair prediction where you will be at 100. But there always is going to be some adjustment once you go from 25 to 100 to where you want your pattern. After getting my pattern adjusted to 2 inches high I go to 200 and see what I'm getting and leave it alone from there.
