FNG with a question. I am in the process of putting together my first medium range gun. It is a .308 Remington 26 inch sps varmint with a weaver 4-20 mil mil tactical. I just ordered Seekins medium rings with there 0 cant base. SWFA said with that scope and a 20 degree base I may not get a 100 yard zero. I am planing on shooting paper and steel at a max of about 800 yards. Not sure if I should have ordered the canted base or not and just wanted to get some opinions. Thanks
