I have both a Marlin .30-30 rifle (open sights) and a Savage .308 rifle (Bushnell 3-9x40 scope). I will tell you right now, the .308 blows the .30-30 away in a heartbeat. The .308 is so wickedly accurate and legendary - that's why it is referred to as the .308 NATO round - the military has used/still uses it.
