Re: narrowed down the choice
I would go with a mildot reticle, even if you are not going to use it for range determination you will get five hold-off points that make long shots more doable.
For field shooting, we do not go over 15-16 since mirage becomes too significant. I like 12-15 power settings for varminting, everyone makes their own choices tho.
Those are all nice scopes - for that rifle and caliber, I would personally go with the 4-14 and not look back.
