Hi,


New to the forum and precision shooting, and just purchased a brand new SWFA 10x42 MRAD scope.


I mounted the base and rings, lapped them, leveled the rifle side to side and front to back, adjusted for eye relief, leveled the scope using the top turret, and when I looked through the scope it looks like the reticle is canted a few degrees in relation to the turrets ( had to tilt the scope to correct it ).


Is this not so uncommon and something I should learn to live with or should I return the scope to SWFA for replacement or repair?


Thanks,

Chris

I've rarely, if ever have been successful in leveling a scope reticle via the turret. I wouldn't worry with it. 
If at first you don't secede...try..try again.

Hi, and thanks for the reply.

Yeah. the top turret not being level could make it seem that the reticle might not be canted and that would not bother me so much.

What does bother me is that in order to get the reticle to center line of sight (not canted) I had to turn the scope to the right so much so that when you look down the center-line of the rings the turrets are noticeably off center to the right, just line of sight without using a level.

Now; if the movement of the turrets track with the reticle than its not so much a problem, but if the turrets do not track with the reticle, and there is a misalignment between my turrets input and reticle than my dope is going to be pretty screwed up, esspecially past 300 yards?

Thanks for the affirmation.

I have a couple scopes for hunting and plinking and never encountered this canted reticle problem before. I thought that it would be safe to assume that at 300+ yards that it could be a serious problem.

I did my research before buying and by all accounts SWFA looked like a stand up company to me, so I felt confident that if there was a manufacturing problem that they would honor it.

Thanks,

Chris

If you're seeing that much cant, definitely talk to SWFA. 

For an otherwise correct scope, I've found it better to use the base of the turret housing than the turrets to align the scope. This works for quality scopes with a flat base and with picatinny rails. You can use stacked feeler gauges and tighten one ring fully so the scope doesn't slip. Don't tighten the other ring all the way or slipping the gauges out gets hard.

I think the best way is to do what the OP described and get the rifle leveled. Then align the reticle with a string on a plumb bob set up 50-75 yards away. If the rifle stays vertical and the air is calm this has worked well for me. I've had a couple scopes where I had them aligned with the gauges and still had a little drift in POI. That went away when sighting on the plumb bob.
Reaction time is a factor...

I leveled the rifle secured on a bench with with two levels; one front and back and one side to side, mounted the rings, used an alignment tool, lapped the rings, rechecked than set the scope in, leveled the scope and adjusted for eye relief  than noticed the problem.

So I checked to see if everything was true with the bore down the center-line of the the rail, receiver, rings, and barrel with a thin piece of white nylon thread and it was true.

So by eliminating the rifle and mount concluded it was the scope reticle off by about 3-5 degrees using my eyball-o-meter.
