To cut through the chase of if you can or can't, If you have or have not, The equipment I believe is what you are asking about. The rest is un important.
Start with a know caliber for shooting long distance accurate. Lot's of calibers will shoot long distance, but few shoot long distance with the accuracy you will want. Some will push the 7MM and such, while they are long range rifles they lack the accuracy you are seeking. Look into something down the line of 6MM or 6.5 ect. As for scope choices-The world will chime in on this one. Most will run in the 32 power range or higher. Straight power or adjustable is your choice . Straight has it's benefits,but lacks the ability to power down on hot days when mirage is a issue. The rest of the equipment is not cheap also. Front and rear rest ( depending on your choice ) can be around $600.00 to $1000.00.
Reloading comes to a new pinnacle also. Components are not cheap. Since in long range shooting Hold over is NOT a option you need to make sure you run with a scope that has a proven record of tracking correct. You need to know exactly how many clicks to go from 300 to 600 to 1000 or 1200 yards. It can not be a guessing game. Once you have all the pcs you need, it becomes range time and practice. After that just go for it. What you will find is the people you will be shooting with ( if you join a club ) will be some of the nicest,helpful people you have ever bumped into,always willing to share info and time to help you. As will the people in here that shoot long range. I must say it is a whole new meaning of the words ,Challenging and fun.

Keep us posted.
