So I got a good deal on as Vortex Viper 6 5-20x44 when I got my Varminteer. It has a BDC reticle. Unfortunately I didn't have the option for a mil-dot which was what I really wanted. I'm about to buy a training rifle and would like to set it up similar to my Varminteer so I can start working on my long range game. Fresh start, do I need to get a mil-dot this time? Is BDC acceptable? I don't see many using it other than hunters? Is there another option in my $4-500 price range that would be better? I really am looking to get some trigger time at longer ranges, but I've never shot past 200 yards. Please school a newbie. Thanks.
