Re: Leveling the Scope Reticle for Long Range Rifles

i use the plumb line to make sure everything is level.i then go to the range and put a 36"piece of white paper on my target backboard butchers paper works.i take my level and draw a vertical line up the target put a dot in the center,then i go 200yds and click my scope up the target as far as i can staying on the target.check the level with the plumb line ,your bullets should follow the line up if everything is working you should have a bubble on your scope to make sure you hold the gun level also.

Re: Leveling the Scope Reticle for Long Range Rifles

Ok so some comment and questions from down under.

Firstly with reference to previous comments to Thomas Haugland's video.

I rate myself able to judge level pretty damn well. Now I will qualify that statement in saying that I wont attempt a challenge of it through a scope but in other trades like situations. And I know a few other top tradesman that can do the the same, but it is by far not the majority that can visually judge level.

Further to that video, Thomas goes on to check the tolerance of the ACD against his digital level and finds exactly what I have found and thought many times; that some spirit levels are a WOFTAM as the marks are way wider than the bubble. Instrument need to be precise. We wont accept a scope that maybe somewhere between .2 and 45. MOA per click so why make ACDs that have a about a 3 degree tolerance?

Secondly, I have been reading this thread and associated article as I am setting up a Howa 1500 in a Boyds in 243 as a entry in to long range. It may see a truing job and re-barrel down the road when my abilities progress.

And yes, as a hunter for 22 years their are a few things in the article I have never thought about because I haven't had to.

But if Bruce could answer a question that would be great. Dependent on machining errors, mounting systems and corrections, from what I have read I may end up with the reticle canted to get the reticle over the bore (Scope is a VX3 4.5-14X40 CDS) Correct?

Now if this is the case, purposely canted, then when I fit the ACD to the scope tube, I fit it on 'Level' with the action leveled, dont I?

Thanks and the threads are always thought provoking which I enjoy too.

Byrnesy, yes it's possible to have the scope correctly aligned to the bore and end up with it "canted" (not parallel) to the action. In this case, align the anti-cant indicator so that it is level when the scope is level.

Re: Leveling the Scope Reticle for Long Range Rifles

Bruce some feedback.

Shot the Howa today and it went well. Will post up a thread during the week.

So firstly, both me and my mate , who is a very accomplished shooter, both thought we were holding the rifle level but alas, no, not according to the ACD.

On setup the rifle was levelled then a plumb bob was hung 20 metres out in front disecting the bore. The scope was then placed in the rings and the reticle leveled. And wow the reticle was dead inline with the plumb line without moving a click. Scope was then removed and rings lapped. Even on sighting I only had to move 3 clicks left, 1/4 MOA.

SCope is a VX3 4.5-14X40 CDS and the mounts are Talley Lightweights. Barreled action is a Howa 1500 in Chrome Moly fluted varmint in 243. All sitting in a Boyds Thumbhole Varmint.

Re: Leveling the Scope Reticle for Long Range Rifles

At what range[distance] was "sighting in" done. How many wind flags or indicators did you have out?
What_____ hand twist is the barrel? What magnetic direction were you shooting? Were these "cold barrel" shots? Which way does the water swirl when you flush the loo or "terlet" as Archie Bunker said?
Have you read the whole post?
