For a 20" DMR in 5.56. Don't have any actual experience with target type scopes, but it seems like it's a trade-off between accuracy (turrets) and speed (ballistic reticle), with a CDS somewhere in the middle. Of course you can get both ballistic and CDS in the same scope, if that makes any sense. Once I find a load that I like I tend to settle on that one load, so CDS might be a good compromise? Thoughts?
