I can only dial out to 150 yds, I'd like to dial to 200 yds.

Will I break anything if I put shim material under the back of the rail near the receiver screws?

Also, the front of the rail is in contact with the top of the barrel. What happens if I remove enough material that there will be no contact?

It definitely can be shimmed if done well. Figure out what thickness shim you will use and put it to the far rear of the base. I would use bedding compound or epoxy under the whole length of rail. Finger tighten the screws down until touching the front at barrel or receiver and rear at shim. Let cure 24hrs or whatever recommendations bedding material says. After cure torque down the screws. You then would have a fully supported rail with built in cant. I would put release compound on the receiver and degrease the rail before bedding.

I shaved down one of those rails to clear a 10/22TD barrel. No issues arose. If you wanted that support you could bed it as well after making the clearance needed for the desired cant.

Or just buy one of the many off the shelf rails made for the 10/22 with the cant you want. Preserving that special edition Ruger rail.

These are great ideas, thank you.

Can you point me in the direction of an extended rail with built in can't?

EGW 20 MOA Rail they also make a 30MOA.

Leopold, Area419, etc make some also.

I like the the EGW 20 MOA rail.  I have one on both of my 10/22's.  EGW 20 MOA Rail Link

If you need more, you can also add Burris Signature Rings to get more off set.  I have them on one of my 10/22.  Burris Signature Ring Link

Got one ordered, thanks for the help.
