I reload .308, but like others said.
What shoots good in my Remington 700 might shoot like crap in your rifle.
Each rifle likes different brass (Yes brass makes a difference, my rifle likes Horandy & Winchester Brass and HATES Federal), Bullet, Bullet depth, AND powder. I really haven't seen a difference when it comes to primers.
(Example, weighing the brass to make sure they are all the same, measuring the volume of each brass to make sure they are the same, weighing all the bullets, weighing each individual powder charge, setting the depth of the bullet to your rifle is critical for the best accuracy, etc....)
To make a round for your rifle, a reloader would need your gun for a minimum of 2-3 range trips with it. Assuming the reloader loads up like 50 rounds of ammo for the gun, with 10 different loads (5 rounds each are the same).
For 800-1000 yard performance, YOU SHOULD have a heavier bullet than a 168 grain. 180's would probably be the better choice.
Now for hunting and target practice thats REASONABLE, a 168 Grain bullet is good.
