I have a custom build 300 PRC with a Defiance Deviant Action. Action also has a 30 MOA rail. I ordered SPUHR ISMS 0 MOA rings. However, it seems the scope is more level than canted down to the barrel. Am I losing elevation with the 0 MOA rings ? PS scope is a 7- 35 x 56 Nightforce F1 with Tremor 3 reticle
