Per Vapodog:
There is no such thing as inherent accuracy. It' s not true that a .308 is more accurate than a .30-06 because it' s a .308. Accuracy is a result of many factors including the shooter. Frankly I believe it has nothing to dowith the cartridge.
Absolutely correct. There really is no such thing as an inaccurate cartridge or bore size, there are only inaccurate rifles and sighting systems!
