Thompson long range was around before all the rest, several of my friends own these rifles and there very accurate. There are several different systems out there whether your dialing turrets or using hash marks. All these rifles take a lot of practice if you really want to be good at long range. My set up now, custom 7mm, night force scope, G7 range finder and all the reloading equipment costs a lot more than a thompson long range set up to shoot factory ammo. Are you a sniper or a hunter, what I'm getting at is you can dump a lot of money in the long range hole. Mark has been around along time he's well worth talking to about what you are expecting out of a long range rifle
