scope zeroing

[Topkat]

I mounted a Barska 10-40x50 scope on my M1A......At 100 yards i'm not even on the paper. Looking down the iron sights and firing a round i'm dead on. Benching while aiming down the iron sites, as I look thru the scope im way high and right. turning the up and down adjust all the way down the scope reticle is still too high (about 2 feet) and is into the stop.
Now what?
thanks as always

Move to 25 yards. See if you are on paper. If not, move to 10 yards.

Once you zero at 25, move to 50, rezero, then move to 100.

BTW, I have had a lot of problems with Baraska scopes running out of adjustment. You could try shimming the rings or using some Burris Signature Zee rings with inserts.

If you have access to a bore sighter, start with that. If you don't, start close and get on paper (as the previous poster mentioned).

Also, did you install that Pic rail on the rifle? If so, is it a flat or canted base?

Keep in mind, you get what you pay for with optics. With Barska's reputation, it could be a problem with the scope itself. People wouldn't be spending $3K on high end rifle scopes if an $80 unit would do the same thing (not that you need to spend $3K… I'm just saying the Barska is at the shallow end of the pool).

The 10-40x50 scope isn't helping matters any either, regardless of the brand.

Way too much power to put on an M1A in the first place.

And very limited adjustment range due to the excess power in the second place.

Do you have a more 'normal' power scope you can put on it and see if the mount is off, or if the scope is just way too powerful to have decent adjustment range?

Check to make sure you don't accidentally have the scope mounted 90 degree's out. The elevation turret should be on top, or facing up, the windage should be on the right side of the rifle, as you look from behind the butt.

If the elevation turret is any place other than on top, you have it mounted 90 degree's off. Been there, done that once.

Post a picture of the scope mounted on the rifle if your not sure.

Never mind, I just open your pictures, should have done that to begin with,my bad.

He did in the OP.

Its mounted right.

Scope has three knobs so it would be pretty hard to do it otherwise.

Get closer and use a bigger target. A sheet of poster board, even a newspaper behind the target to see where bullets are impacting so you'll know where to begin.

I shimmed the rear ring .012'' and at 50yrds the vertical axis is good now. yay!
but L/R is at the extreme left edge of the paper and im out of adjustment :banghead:
What now?
thanks for all the input!

I sent the mount back, it sits cockeyed on the gun.......weird.
Thanks for your help folks

No kidding! A 40x scope is way too much for most applications, especially when you consider the gun it is mounted on in this instance. Plus, it seems like higher magnification doesn't usually work out in cheaper optics.

For whatever it's worth to mention it, I run a 3-20x on my bolt gun, and I routinely shoot that rifle beyond 1,000 yards (was shooting at 1,250 yards with it earlier this week, in fact). At those distances I'm engaging IPSC targets, or 10-12" steel plates. You can see plenty with 20x for those applications, even at those distances. Some of my friends use 5-25x scopes for that kind of shooting, which is also fine. But, I also find myself in situations (quite often) where heavy mirage prevents me from even using 20x effectively (I've had to dial as low as 10x on heavy mirage days).

if you knew more about the "sight" in process, you would not start at 100 yds.

Set up for 25 yds. Get that puppy spot on or what ever your happy with. Move out to 100 yds.

You can google the process as well. U-Tube also has a tutorial on the matter.
