Ruger No3 22 Hornet scope problem

Won't fix the Ruger base and ring issue but I have a set of Weaver bases that came off a #3 and were replaced with the Ruger OEM bases and rings. If you want to try them you'll need Weaver style rings but at least you can get the rifle shooting. Pm me your address and I'll mail them out no charge.

FWIW I've had three of the #3s and have not had issues with the Ruger bases and rings.
I have the Weaver bases on my #3, they came on the rifle. Using Burris rings, works great
 
I have a 1” aluminum dowel and a 30mm for scope work. Makes turning in dovetail rings easy and much better for the scope.
Also come in very handy when alignment issues need solving.
Just from the original picture the scope appears to be angled down towards the muzzle end. One ring is not correct.

Yep. I have the Wheeler scope alignment tool. Believe it or not the alignment is fine. It is just the angle that is off. Also lapped the rings with the Wheeler lapping tool. Didn't do anything to resolve the issue though.

I have a similar problem with a #3 in 22H, but you are way ahead of me!
Mine came with a copper shim under the front scope mount which was not a Ruger mount.
I picked it up when I returned from Desert Storm and Ruger told me the early #3 did not have Ruger scope mounts which fit.
I wouldn’t mind trying leftover parts to try and find something that does work.

I once had a hell of a time with a Winchester USRAC M94 XTR AE in 7-30 Waters. The gun was truly beautiful with a 24” bbl, deep blue, cut checkering and I wanted a really clean ring and base setup to compliment the rifle.
I had 2 readily available choices; all steel Redfield or Weaver tip-off rings and bases.
I went with the Redfield and quickly regretted it. My friend who happened to be the head gunsmith where I purchased the gun had 2 additional Redfield setups, all 3 had the same issue.
Someone somewhere at Redfield must have had the wrong dimensions given them when they drew up the CAD program for machining the bases.
Every one held the scope on a slightly less than parallel plane than the bbl.
Kinda disgusted I swapped my Redfield rings and base for the Weaver setup and bingo, the problem was solved.
I guess my point is……. if your No.3 has the original bbl is there an alternate base and ring setup available for it.
Anything can happen, maybe the base is indeed, machined incorrectly?
 
I received a set of Weaver bases from another member and problem solved. Someone at Ruger dropped the ball on this one but that is fine. I am still a big Ruger nut so I will let it slide.

Absolutely, I have plenty of Rugers too.
I also wouldn’t be surprised if some accessories are outsourced.
 
Weaver #85 and #86 with a note saying the front base may need to be modified and back base may need to be shimmed for perfect alignment I have these on two #3s and they work just fine right out of the package maybe im just lucky

I have a 77 6mm with the receiver machined for Ruger rings that I had to add about .010” shim under the front scope ring, it happens.
 
A followup on this as I did order the "tall" front scope base from Numrich referenced in above post. It appears Numrich does indeed offer the correct front base for the No. 3 rifle; a big "but hold on" as I ordered two and got two different sizes... One was the correct No. 3, and the other is the 1V front base as you will see in the photos below. So it appears Numrich has a bin with mixed front sight bases and it may be a bit of a crap shoot to see which you would get when ordered. In photos below the 1V is on top with a "2" cast in underside. The No. 3 base has a "1" cast in underside. I confirmed measurements posted by Gramps51 and G2 in this and previous threads for the No. 3 base.

Thank you for the help. I found an auction on FleaBay that closed with no bidders before I saw it. I messaged the seller and he was nice enough to re-list it for me, Now I have bases on the way. I should have rings already.
I would also gladly try Ruger rings/mounts/bases If some are for sale.
I also have a Win M70 XTR in 7mm RM that is a problem. The XTR has holes drilled off true so far that I have never found a scope with enough windage adjustment. I am told there are mounts with enough adjustment to correct for that, but I have no clue what to buy. Suggestions?

I have used Weaver Grand Slam rings for this issue- they are windage adjustable. I don’t believe Weaver offers them any longer, but I see NOS rings sold on eBay. There are also other windage adjustable rings by other makers with which you should be able to compensate for the misalignment of the mounting screw holes.
 
Leupold I believe used to sell bases that were for custom applications. These were basically blanks with I seem to remember the top dovetail machining done.

Or, maybe a good gunsmith could move the base or bases (2 piece) slightly and re-drill your receiver to allow proper scope mounting?
 
This is not a case of the holes being drilled improperly. As you can see in Celler 71s post above, it is a case of the front base not being the correct height.

I was referring to the M70 problem.
