I have that exact scope but with the .223 reticle. If I had to do it over I would probably choose another scope over this one. This scope holds zero but it's not overly forgiving in regards to eye relief and the eye box. I've found that if you don't keep your head in about the exact same place every time you don't get a good sight picture, I know consistency is the key to accuracy but nobody's perfect. As expected with a low end scope the glass isn't overly clear at the highest(usually above 9x)settings and it doesn't gather as much light. At lower setting the scope is much more forgiving.
As with all the BDC reticles you will need to shoot your particular load and see what range each dot is on at, it will not be the even numbers that are stated. This is how the BDC reticle is set up on my rifle:
20" barrel shooting .223 PMC X-Tac Match 77gr OTM
Crosshair- 100yds
First dot- 232yds
Second dot- 322yds
Fourth dot- 396yds
