Sighting in a 25 yards...

I've talked to a couple of guys that say you can sight a rifle in a 25 yards and it's dead on at 200 yards. Ofcourse, I would not trust this and would want to check it at 200 yards anyway.

I'm a firm believer that "paper doesn't lie" and if you want to know what your rifle's doing at a particular yardage, you have to shoot that yardage to know.

Has anyone heard of or used this method of sighting in at 25 to 200?
Does it work?

Your opinions and experiences are appreciated.
Thank you, Bowhunter57

Re: Sighting in a 25 yards...

If your shooting a rifle that shoots over 3000 ft sec in my experience it will be about dead on at 300 yds if your dead on at 25. The way I normally bore sight mine is put a 2" dot at 25 line everything up bore, scope all that jazz shoot a few make sure I'm hitting the bottom of that 2" dot and normally I'm very close to being dead on at 250 yds.

This is my experience hope this helped,

Nathan

Re: Sighting in a 25 yards...

yea i could see where this might work for some rifles but i would say the same thing as you. If you want to know where it shoots at 200 then shoot at 200. There are so many varables, velocity, scope height, bullet BC and others.

nddodd,
I should've mentioned that I'll be sighting in a .25-06, so it'll be over 3000 f.p.s. As long as it gets me within a couple of inches of being dead on at 200 yards, I'll be happy. After I'm close enough at 200, then I can fine tune my P.O.I. without wasting ammo and/or guessing where the rifle's hitting.

Good hunting, Bowhunter57

with a 100 grain bullet with a BC of .400 shooting 3300fps if you sight it in at 50 yards then you will be almost dead on at 200. It might work better to sight it in at 50 yards if the gun shoots over 3000 fps. Just an idea

That sounds like a good plan. I take my bolt out, and look through the barrel. That gets me on paper, usually 2" from the X at 100 yards. I, then, sight in 2" high. That process usually takes me 6 shots.

Re: Sighting in a 25 yards...

25/200 is an Army tradition for battle carbines, and it's ballpark accurate. Unfortunately I think it's way too sloppy for hunting or - especially - precision rifles. Also, the ranges have changed now to 25/250 and 25/300.
