Is this night vision scope effective at 300 - 350 yards? I want to use it on coyotes that come into my farm yard. I am shooting a 25-06 and have killed coyotes at 575 yards, so I want distance with a night vision scope.

When I zeroed mine I did it at 25 yards ironsight, and 50 yards scoped. The effective range isn't that far on the standard .22 but in the end it comes down to personal preference.

Any scope will work on any gun. Its effectiveness requires your to match capability with need. A rimfire scope is intended for a 50 yard zero. If you expect to do most of your shooting at 50 yards, it will work fine.

He is right the bullet at most will be 1/2 high at 50yards. Zero at 100 if sighted correctly. The bullet is flat to about 100 yards and will drop significantly for the next 300 yards. At 400yards your drop is almost 7-8 inches and at longer than that the bullet loses most if its effective stopping power for hunting and the drop is really significant. Not worth the effort......

At night. You can sight in the 390 during the day in simi-darkness with a day light lens cover over the front of the scope. (the snap cover has a small hole in the center for look see during the day) 50 foot room with a target, bench rest and a rifle vise. You'll also need laser bore sight Figure you rifle ammunition ballistic and how many yards before it starts to drop. Set the 390 reticle to the red do on the target one or two inch above. Dead center set up will give you about two hundred yards on center... approx. Now you know this is a static test or sight in. During night because of some distortion and noise from the scope. stewbison

Hello, yes you could but the scope is limited the clarity of the image intensifier tube with effective range from 0 to 80-100 yards max and if you get this out of it. The only difference here is the 1,5 85mm lens. Most lens are 45 or 50mm. So with the 85 mm lens which lets in more ambient light and with a brighter IR illuminator you might get a 100 yards or more. You have a Russian manufactured monocular the Famous Trails has installed their name and logo. You have a generation 1 ex-soviet union image tube. It painted green like the Soviet military.

If you are trying to focus at a relatively close distance, you may be overpowering the scopes ability to focus at that distance. Most rifle scopes are set to parralax free at 100 yards.You can see this effect by putting the scope on its lowest power, focusing at 25-50 yards, and then increasing the power setting. You will see the image go out of focus as the power increases. This simply means that you must shoot at longer distances in order to use the scope to its full potential.

The other problem may be your parallax adjustment, but you may have already tried that solution.If not, make sure that the adjustment dial is set at the distance you are trying to shoot (minor adjustment from the indicated setting may be required to fine tune the image).

No, this is not a scope issue. The scope is raised above the centerline of the barrel, thus at 10 yards, the barrell is actually slightly raised in relation to the centerline of the scope in order to hit your point of aim. Since the front of the barrel is slightly inclined, at 25 yards the bullet is still rising in relation to the scope alignment. Backing up to 50 yards you will begin to see the bullet start to drop back down, at 100 yards it may drop as much as 8-10 inches, and at 200 yards, it may drop as much as 52 inches. This is assuming that you are shooting a standard velocity .22 long rifle cartridge (1050 feet per second or so).

The Tasco is not a 600 yrd scope by any means. If you want to get rid of them, there are plenty of deer hunters who will use it at 100 yards and never go beyond that. The MOA is usually imprinted on the windage dial, it will have a little fraction or a decimal there telling what it is at 100 yards. There are a couple good scopes out there, Nikon and Pentax are decent. Leupold is about the best. It will deliver beyond your eye vision and rifles potential. I have a Bushnell on my M-40, mainly because I can't afford a $1000 scope, but I can shoot door knobs off at 200 yards all day. The scope is a piece of junk, but I have it set up right and it works, Hope this helps.

The Bushnell 3-9X40 has been around for quite some time in several forms, but it is pretty standard to set it like any other scope.

With the gun resting solidly on sand bags or something like a Lead Sled, shoot at a target with a 1" grid on it. Those targets are a free download at http://targetz.com/, but you have to browse to find them. Targets No: 10049 or 10058 are both usable, if you can see a 1" aiming point with a 9 power scope at 200 yards.

With a known point of impact (POI) at 200 yards, you can move the POI to where you want it (inside the caps at the center of the scope, there are adjusting screws or slots). The norm is 1/4" per click (the adjuster can usually be felt to click) at 100 yards or four 1/4" clicks for an inch. At 200 yards, the adjustment will be twice what it is at 100 yards or 1/2" per click.

Make your adjustments, using the grid on the target to tell you how many inches it needs to move, and shoot the target again to confirm the adjustment is correct. It's pretty standard to shoot at least a three shot group to ensure the bullets are reasonably close to each other.

Another method is to set the POI at a certain number of inches high at 100 yards and assume it's right at 200 yards. If the mid range trajectory, for your cartridge, at 200 yards is X inches high at 100 yards, you can set your POI to that X inches high and be pretty close at 200 yards.
