Beeman 25 to 55 in dead air ...

Is it a common thing to be spot on at 25 no change in horizontal ,pretty much stacking the pellets ,then shoot at 55 and be 3/4 to the right ? Conditions: 0 wind and rifle is shot off front bag off of palm of hand .I feel I can hold and shoot the rifle at 55 the same as 25.as far as keeping still ,my reticle is spot on static at the same POA .Wondering if clicking up to zero for 55 changes horizontal as well ? Idk?
 
best method ever that ive ever used to align a scope to the bore is the mirror method.

it perfectly aligns the crosshairs with the bore.

get a mirror,
set it up at say 5yds,
set your scope to 10 yds (or when its focused in the mirror)

look through the scope at your reflection in the mirror (a steady gun rest helps)

loosen the scope ring screws and rotate the scope till the vertical crosshair intersects the center of the bore when the crosshairs are centered on the scope objective.

"bam" your crosshairs are now aligned with the bore

snug your ring screws and recheck,
repeat till perfect :cool:


then use a plumb line to get a vertical line,
move the gun till the vertical crosshair lines up with the string adjust and and lock down your scope level,

now everything is lined up and if you miss its your own fault LOL

Thing is .that I did optically center the scope with the mirror method with the difference of me holding it tight to the mirror .Lined up the shadow reticle to the etched reticle.Leveled rifle and made a plumb line on wall to line up the cross hairs .I'm left scratching my head ? Lol
 
Thirty yards further 3/4" drift in either direction isn't unusual. Most guns the barrel isn't perfectly aligned with the dovetails. Not to mention most rings aren't perfectly aligned with each other. There's various methods of aligning the barrel so the horizontal plane stays true.

Typically I'll center a scope and use trusted good rings like Sportsmatch, mount the scope with a plumb and level. Then I bend the barrel to the centered scope at ten yards indoors. Then I test it at thirty yards in a dead calm. If they are centered at both ranges it'll stay true at longer distances.

Horizontal barrel alignment is critical because your zero will only be correct at one range if it's off.

totally different "mirror method"

what you did by pressing it tight to a mirror,
was set your scopes adjustment travel to its center.


the mirror method i posted is to align the vertical crosshairs of the scope to the bore of the gun.


2 totally different things :cool:

When you say " bend the barrel" is that literally bending the barrel? I've heard of bending the barrel to alleviate barrel droop but not for horizontal?

Ahh gotcha now ! So my scope is optically centered but not centered to bore so to speak. So I'm gathering when your back from the mirror at 5 or 10 yards the image you see in the scope is your crosshairs and the business end of the barrel from the mirrors reflection .
 
Wow ..I've never thought of that mirror method for bore alignment .I've always leveled the rifle itself the sat the scope in the bottom rings and adjusted to a plumb line on the wall .Seems like this mirror method is more precise and you actually get to see the vertical crosshair split the bore .Has to be more precise ! Yea if you could get that picture up ..would be sweet to see this .I'll have to clear out some furniture to get a good 10 yards back from the mirror over here lol.

im not understanding exactly what you're asking.

but no,
just because you have previously set your scope level to level with a plumb line it does not mean it will be centered to the bore,
the mirror will show you the way lol
:cool:

this method does not have anything to do with adjusting the turrets.

this is just for getting the reticle lined up,
after that youll still have to sight in normally.

Often scope rings or mounts are made for universal dovetail fit so they're not even centered on the receiver. Sportsmatch are the closest I've found to being centered on my eleven mm Weihrauch dovetails.

The plumb line should theoretically center your scope over the bore once the barrel is aligned with the receiver or compression tube.

I place a level on my breech block and plumb the vertical cross hair. This promotes true plane adjustments and gets me close enough for my accuracy abilities.

Others may have better more precise methods but this works well enough for me.

Agreed, most gun barrels are not perfectly aligned with the receiver. A good way to test this is to put a rear peep on at the back of the receiver, not the breach. if it is not aligned in the center of the receiver, your barrel and receiver are not aligned.
