Hello. I am about to purchase my first bolt gun from snipercentral, and I am stuck on which scope to choose. I only want to spend this amount of coin once. It is alot of money for me. I want to target shoot starting about 200 yards, and eventually work out to 800 -1000. I have a 1000 yrd range 2 miles from my house. My 1st choice is the Bushnell 4200 6x24x50. My second choice is the Leupold Mk4 4.5-14x40mm LR/T Target. Could you suggest which of these would be best for the type of shooting i will be doing? Quality of glass. Thank you very much.
