Am waiting on a new scope for my AK. If I sight it in at 25 Yards not meters will it be pretty much right on out to 200 yards? Thanks guys, Bud

28 yards = 25 meters.

If you are hitting point of aim at 25m, you should be really close at 100m. at 200 you would be a little low.

Its pretty tough zeroing at 25 yards... but its easier to zero at 100 yards and then shoot at 25 yards. If you plan to zero at 25 yards and then zero at 100 yards I would recommend not touching the elevation on the front post, but just adjusting the windage on it. Then using the elevation adjustments in the front post to adjust at 100 yards.

My yugo m70 was pretty off and I had to play with it some - I did more bad than good trying to zero at 25 yards and ended up buying a laser bore sighter for my rifle since I jacked up the adjustments so bad - that worked for windage but not for elevation.

A friends wasr was dead on and needed no adjustments - his rifle is more accurate than the m70 :(.

Not with a 7.62 caliber rifle.

If you zero at 25 you'll be way high at further ranges. Zeroing at pistol ranges is like bore-sighting. It's okay to use to get in the vicinity, but trying to actually use the rifle at longer distances without zeroing further out is usually futile.

If you use 50 yards as your "near zero", you should be pretty close all the way out to 200 yards.

I sure agree with what you post about sighting a rifle at a 25yd pistol range, it gets you something on paper but what real good is this?

5.45 Russian ammo runs around 2900 fps.

Rear sight slide set at 100.

If zeroed at 25 yds. bullet impact will be 2 3/4" high @ 100 yds.
4 1/2" low at 300 yds.
This is the range I prefer to sight in at.

No good unless you already have the trajectory data in front of you. Assuming you do, sighting in with a new rifle or sight at 25 yards/meters is usually safe (keeping all shots in the target area at sensitive ranges), quick and prepares the rifle for sighting in at the longer distances. Once you have satisfactory results at 100 yds/m, you don't need the 25 yd range anymore unless you change a sight or make some other major change on the rifle. Read any military manual for sighting in rifles and you'll see that this is a very common practice. The U.S. military 25m target has a very small silhouette on it that's the size of a full-size silhouette at 300m. The sighting is set up for a near zero at 25m and a far zero at 300m. The small silhouette is an efficient way to show the shooter how small inaccuracies at 25m mean big misses at 300m.
