One thing to keep in mind is recoil shock on the scope. I have had bushnells,redfields, of course tascos recoil shatter w/ my 300win mag and 30-06. If you are going to use a short action caliber (308 class) it may not matter. If your useing a long action or mag. dont scimp on the scope even if it stretches you to buy it. I have a aetec on a 6mm and love it, I just dont know that I would trust it on my mag. Leupold cant be beat for the price, did you look at the vari-X II 3-9? I pick them up on sale for $199.
