I am wanting to update optics. I have a .308 and plan on shooting out to 1000yds mainly for competition. Do I need 5.5-22 or 8-32? Right now I have a junk Famous Maker 8-32 scope and don't like shooting 100 yard to 300 yards with it. I have a very small site picture because of the higher magnification or the junkyness of the scope, I don't know which. So therefore I need the advise of others. Thanks in advance!
