If you want a long distance calling plan, expect to drop over $2K. Before some of the cheap skates here tell me it can be had for cheaper, I'm talking in the 800+ meter range. When playing out there, to do it right, you'll want a few things.
#1. Rifle - Calibers will vary, but you can run anything from a 6.5 Grendel out to a Barret .416 for the long distance sex.
#2. Optics- Granted iron sights were sweet back in WWI/WWII, you want to see the prize, not SWAG it. (Scientific Wild Ass Guess)
#3. Bench rest - I don't care if you're solid like a brick house or twitch like Mohammed Ali, the bench rest will keep your rifle on to sight in your optic. Not to mention get a good bore sight going first.
#4. Spotting scope - Where your scope is powerful, the spotting scope puts it that much closer. Going out past 1000+ every round will give off a "vapor" trail as it flies down range. Another person on the spotting scope can dial you in a little better. Not to mention check down range windage and possible elevation changes caused by weather.
#5. Ammo - the match grade goodness from say Black Hills, isn't the cheapest in the world. Meaning $45+/box of 20 depending on the caliber obviously.
There's a few more toys you can buy like a shooting mat, laser bore sighter, portable weather station etc... to help you accomplish this. But a working knowledge of ballistics, elevation, windage, and atmospheric conditions all come into effect when making those kinds of long distance calls to paper or flesh. That's all the more reason the long distance shooting is fun and not to mention a skill that takes time and patience. There's quite a few semi-autos and bolt guns that can fulfill the long range urge. It'll depend more on you as a shooter to what you feel comfortable with.
