How to bore site a gamo BB gun.

[moose]

Bought son a gamo BB gun for x mass. Came with a scope need to mount it but how do you bore site it when you can't take the bolt out. Don't feel like spending money on a lazer bore sighting light.

Take it out back and start close and just adjust the scope from there. Keep moving farther back and get it dialed in. OLD School. Never bore sighted anything.

Lol at this bore sighting and laser sighting business.

Start at 5 yards and get it about 1" below POA.

Depending on power of this airgun and the height of the scope, you may be zero at around 15-20 yards.

If you have something like a Black & Decker clamp bench , you could do this . Break the action open after mounting the scope . Look through the barrel and Lock onto an object about 20 feet away . Then adjust the scope so the crosshairs are on that same object . Fine Adjust the scope out of the vice .

Or , do what wdswtr said ............

buy 1000 pellets and shoot shoot shoot.before you are 1/10th into them used up you will most likely be in sight,

Yep or clamp it down, shoot once, mover crosshairs to where projectile hit target.

oops ! Forgot that one .

As far as I know , pellet guns are not consistent shooters .

Clamping down is probably not realistic advice for an airgun, as you'll have to pump it, or break the barrel to charge it up.

Unless it's a CO2 gun or a PCP, clamping usually is not an option.

I have sighted lots of airguns and usually just start at 20yds on a big piece of paper and move the cross hairs as need. Pellet guns can be vary accurate. I have one that will shoot sub MOA at 100yds. BBs not so much, but still can be decent at close range. Wind can be a killer with this light ammo at long range.

setup a target. start close and move back. bb's are cheap. we're not talking .308 ammo here.

caution on BB guns. they are more prone to richochette than pellet rounds.

I sure think it is realistic to get the scope on target. You only need to shoot it once and then move the crosshairs to the point the bb hit the target. Now your on paper and dial it in from there which should be awfully darn close to spot on.
