Anyone still use a Bushnell Bore Sight Tool (743333) to Set Up a New Scope?

[KnightExtreme]

Been using 1 of the Bushnell Bore Sight Tool (743333 Model) for a long time. Trying to Set up New Scope on a Rifle and the Scope WIndage turret is far to the right and when I attempt to dial it to the Center of the Bore SIght Grid it is max to the left but at number 5 left of center of the grid. Is it that the Scope is deflective? I put a different old Scope on and it dials right in to the Center of the Grid with the same Bushnell Bore Sight Tool. Same Rings Same Base. Appears the "New" Scope is bad?
Please advise (This is the First Time I have had this happen). Mount a few scopes and they have always been able to be adjusted to the center mark of the Bore Sight Grid.But not this Scope?
Thanks,

used one for years and with tons of setups. if it's a setup where all you did is pull the ring tops and install a new scope check how much adjustment the scope has compared to the old one. if you replaced the rings too redo everything and maybe even flip part of the setup and see if the issue goes to the other side. if it's all new see if the barrel and scope are actually not aligned, check scope holes to see if they're straight, eye down the holes to see if they follow the barrel through the muzzle.
was rare to have one dead on but they were almost always on paper at 100. did have issues with some of the 1" tubes not having enough windage to get to zero on setups that were.......less than correct.

What scope? There are scopes out there now that have zero stops on the windage. If yours has that, that could be what prevents it from dialing over far enough.

Burris Fullfield E1. Appears it is Different than my Other 2 Fullfield If it Does? Never had any issue getting any Scope To Align with the Grid but This 1. So Much for the ability to Get it dialed in. Expected it to be the same guess Not!

You could try mechanically centering the reticle and then remounting/bore sighting. Is this a brand new scope, one you've had or one you bought used?

 

[KnightExtreme]

Not sure what you mean as to "Mechanically Centering" I never needed to do that with my Older 2 Burris Fullfield Scopes but this 1 is Brand New bought in Nov 2025.
Why would they change what worked prior? Just will cause more CS required help. (at cost to them)

Bottom out the turrets... then turn all the way out, counting revolutions, Then turn back halfway. So if it's 6 complete revolutions, turn back 3 and it's centered. Then you're starting with the scope centered.

It's just something to try and see if it helps.

Yeah, I use one of these Bushnell gadgets, super nice, saves a lot of time, and lets me do a grid tracking test on a scope without burning ammo.

My thoughts - some guns just have really poorly aligned scope bases. I have a Rem 700 that's bases are off by like 30-ish MOA from center. So on that gun, I can just barely zero a scope with 60 MOA of internal travel., Scopes that only have, say 50 MOA of internal travel, will not zero on that rifle (at least not unless I use the Burris Signature Zee rings with the offset inserts to correct for the bases mis-alignment).

I just checked current specs, and the Fullfield E1 3-9 only has 50 MOA of internal travel, the 4.5-14 has 40 MOA of travel, and the 6-20x50 only has 30 MOA of internal travel. However, when I asked AI the zoom ranges on Burris's older Fullfield scopes, mostly had a lot of adjustment range (Most Fullfield IV scopes had 70 to 100 MOA of internal adjustment). So the E1's seem to have a pretty low adjustment range.

So my hypothesis is thus:

1) Your rifle likely has some misalignment of scope rings/bases (almost certainly true, ever gun I've ever looked at was off at least a few MOA)

2) Your older/other scopes had more range of adjustment available. Even if their specs said less, practical reality is often more - I had an old Vortex once that was rated for like 60 MOA or, but counting squares on that Bushnell grid, it would really do like 86 or somesuch).

3) Your new Burris E1 is likely the 4.5-14 or 6-20, and doesn't have enough internal range to accommodate whatever misalignment you have in your bases/rings.

You could correct that by using the aforementioned Burris Signature Zee rings with offset inserts, or you'll need to use a different scope on this particular gun.

I am in total agreement with this hypothesis after reading the several paragraphs I was sent outlining the issues with this gentlemans scope.
