Anyone Shoot with a Bubble Level for their Scope ?
Just handling my new Condor even without the scope mounted yet, I can see the potential for rotation. I am thinking about getting a bubble level to mount on my scope.
Many complaints listed on poor quality reviews….
Does anyone else do this? Any recommendations on brands ?

Theres no absolute foolproof way to mount a level, but you can get pretty close.
My levels housing was turned on a lathe, so the end surface is as close to 90 degrees to the bubble as I can get. The level is now screwed to the side of the scope rail. The rail I assume is 90 degrees to level, since the rail doea not appear bent.
My level is shown here. http://talonairgun.com/forum/viewtopic.php?t=17647
A small good quality could probably be held in place in a similar fashion, and you could use it as reference to rotate a scope-mounted level to the same orientation.
Now I placed the rifle in a rest and positioned it until the bubble said the rifle was leveled. The rifle was pointed at my 50 yard target which has a vertical line drawn down it using another level.
Now I compared the vertical crosshair to the vertical line. Since the crosshair actually covered my drawn line, i positioned both side-by-side and it was easy to tell how much to rotate the scope in the rings. Once I got it, I sighted the rifle then shot at different ranges to check for horizontal POI changes. There werent any, so I am satisfied the level is correct.
Shoot at targets from close to far that have a vertical plumb target line. With perfect alignment the POI will hit the vertical line regardless distance to the target. With a canted rifle the POI will move further from the vertical line, to the right or left as distance to the target increases.
I looked and couldn’t find an alignment method, but this is what I would do. Both methods involve shooting targets at 50-75-100-150 yards.
1. Point scope at a blank wall or clear sky, look through the scope and align the bubble with the horizontal cross hair, they should be parallel to each other, shoot at several targets with a vertical line and see if POI tracks to left or right of the vertical line on the targets of different ranges. Move scope and not the bubble to align the POI onto the Vertical line on the targets. Do not move the elevation or windage adjustments
2.With a scope that is in alignment, use another level, placed on the receiver to level the rifle, attach the bubble to the Scope, bring the bubble on the scope to level. Shoot the targets from close to far target. Move the bubble and not the scope to align POI onto the vertical line of the different targets. Do not move the elevation or windage adjustments
Success will have POI on the vertical line of the target at all the different ranges.
There are probably better methods so someone else can chime in?

Very well made.

I fear this is one of those stupid questions……How do you know you have it mounted perfectly level or plumb?
good to hear from someone that is a good product. seemed the best of what I had found.
Cant go wrong with these……I had a couple.
Very well made.

Thank you with the .25 LW barrel and the 858cc tank it is a real killer very accurate and predictable.

Randy that is a nice set up there, very nice
Love mine with MilDots, bubble level inside, rubber coated exterior, and a red laser for those shortrange shots can’t be beat for 90.00!

I think from center of the barrel to center of the scope is about 2″ on the blaser. Maybe a hair less.
I thought about that, if it doesn’t matter at 500 then it doesn’t matter at 100. But I am adjusting 8.75-9.5moa elevation (depending a few things) and just a couple moa for windage for shooting at 500 yards. If an airgun is sighted in around 25 yards, is the same amount of adjustment or more for an airgun at 100 yards. So it will definitely come into play sooner, but you are still going to be reaching that airgun out.
Another thing to note, is a lot of us use scopes like leapers and centerpoint on the pellet guns. There is absolutely no point in a bubble level if your scope is crap, at least for the adjustment part. You may have it level, but there is still no telling where you will end up when you adjust 10moa on one of those. A bubble level is for that little bit of extra refinement, if there is no refinement to start with, that little bit won’t get you very far.
Good to know Lama. How far apart is your scope on your powder guns compared to you old A.F. rifle? If it doesn’t come into play @ 500 yards it Damn sure won’t matter at 100.
Speaking in long range shooting terms…
When you adjust, it adjust along the lines. So if your rifle is canted, and you adjusted up 10moa, what you really did was adjust up less than 10moa, and left or right a few moa. And it keeps getting more and more the farther you cant. In an extreme example, if you had it canted 90 degrees, and adjusted up 10 moa, you adjusted the windage 10moa, and none for the elevation. Obviously you would notice 90 degrees, but you get the idea.
I guess if you were using the marks in the scope to hold over when shooting, if you canted the scope you wouldn’t hit on the line, but a little to the side.
The effects of both get greater the farther you are shooting and the more drop you are having to compesate for. I shoot out to 500 yards pretty often with my powderburner and have never had any trouble, so I don’t think it is really needed. If you got into some serious competitions it may help, but short of that, if you have faith in your ability to hold it mostly level, you are ok.
I’m new to optics (Always preferred open sights) I believe the greater the distance and the smaller the target or instant kill shot the more important everything lines up. Also the greater the gap between bore and line of sight (Low rings/high rings/Tri-rail no Tri-rail/Objective bell size)Comes into play. It all adds up.
I have no level on my rifle. Quite often I take shots at game with the rifle not particularly level, and it doesn’t make a difference?? Maybe for top end compo’ target shooting, but out in the field they drop just as dead..

When on uneven rugged terrain it makes all the difference.
Sometimes you think you have your rifle straight when in fact it is canted about 20/30 degrees. When shooting at 60+ meters you’ll miss.
