I have to laugh when people either don’t read the question before answering, or they have no idea what they’re talking about. The rifle setup you are building is not being built for hunting, as stated in your question, also you have chosen a great round (.308 or 7.62×51 NATO) for competition shooting. Altho if you’re planning on target shooting out to 1000 yards consistantly you’re better off with a .300winmag or 6mm.br or even a 7mm magnum. Most bench shooters that use a sled for long distance shooting use their own handloaded ammo in complete custom rifles in “exotic” calibers, tho the 3 I listed above are also very suitable.
Your scope choice should have a wide field of view at full magnification and distance.Allowing as much light into the tube and reticle as possible increases shot placement consistancy. The scope you have chosen is a 12 to 36 power with a 80mm objective, giving the scope a tremendous light gathering capability at full power and distance. Depending on the rifle and stock you use, it’s very capable of giving consistant .5moa groupings at 200 yards.It would be best suited for 200 to 500 yard shooting simply because of the magnification, not the caliber .308 bullet. .308 is very capable of reaching 1000 yards accurately and consistantly, but it’s easier with a bullet more suited for the job, like those I mentioned above. You’re scope should have no more power than can be accurately reached by your caliber at maximum effective range. The scope you have chosen is underpowered for your caliber at maximum range, but is very suited for your caliber at shorter (200 to 500yard) ranges.
