Welcome to Long Range Hunting Kevin.
Your Leupold will do the job for you if you're just getting started. If money is an object, you can send it to Leupold and get target turrets put on it and have in back in about a week total. I've had this done before and it works out well. I think I paid about $110 for the last one I had done but that was 2 or 3 years ago.
Then, in the meantime, you can use your Leupold and then see if you still want to spend the bucks on a Nightforce. I use a NF and love it.
Or you could just pop for the NF now and be a very happy camper.
If you have further questions try them in the General Forum or something similar as you'll get a lot better response there. Not everybody reads the Members Intro forum.
Good luck with you new gun
