If you want a "long range target rifle" I wouldn't go with the PTR or FAL, they are both incredible rifles the FAL is accurate and has great ergonomics and the PTR is rugged as all hell but neither are real standouts for long range accuracy
If you want a good semi-auto 308 for long range I would go with an AR10/LR308 or a Springfield M1a. They are both well known for there MOA capabilities, the AR10/LR308 is best suited out of all four rifles for optics mounting, all 3 other rifles are "difficult" to scope in comparrison. Also the AR platform will hold a zero much longer and will produce far less felt recoil.

"In a nation ruled by swine, all pigs are upwardly mobile—and the rest of us are F###ed until we can put our acts together: not necessarily to win, but mainly to keep from losing completely. We owe that to ourselves and our crippled self-image as something better than a nation of panicked sheep."-HST
