Good to know! Thanks.
Question: What if I put a -10 on the bottom front ring and a +10 on the bottom rear ring with 0s on the top of both rings?
It may be better to do as you did for proper fit and gripping power. Just thinkin' out loud, as I have the 10s on hand but no 20s.
That's what I did on my 270 AM but never really noticed as the thing shoots flat enough that 0 MOA cant is sufficient.
Roy, I have used them a lot, but never on a 338.
I used then for many years on a none braked 300 RUM sport using the 1" Grand Slam Weaver Scope and also on a braked 300 Rem. Sendero. Also have used them on braked Rem. Sendero using 30mm ring dia. on my NF.
I would not hesitate to recommend them and use them with confidence.
Went on a Elk hunting trip from West Nevada to West Colorado; we did some mighty rough 4wheeling and when we got back home (Nevada) my zero was dead-on!
Now

I have never done that. The way I see it you have the maintain the proper ring opening diameter for the right grip. If you off-set -.010 on the bottom then to maintain the right dia. you have to use +0.010 on the top; if you use zero, which means the ring internal diameter would be 0.010 bigger they might not give you the awesome grip they normally provide.
I have used them like:
In the Front: -0.020 on bottom and +0.020 on top.
In the Rear: +0.010 on bottom and -0.010 on top.
For A Grand Total of 0.030.
In the Front: -0.020 on bottom and +0.020 on top.
In the Rear: 0.000 on bottom and 0.000 on top.
For A Grand Total of 0.020.
You could do:
In the Front: -0.010 on bottom and +0.010 on top.
In the Rear: +0.010 on bottom and -0.010 on top.
For A Grand Total of 0.020
But never mixing them like you propose.
Something I really like about them, they will rotate properly to accommodate
themselves without leaving any marks and providing mighty awesome grip.
Man! I could become their sales person...
What ever you do, wish you the best!
