Hey there - new to the campfire and hoping you guys can answer a question for me (no real experience past 300 yards).

People are using 308's for 1000 yard shooting with good success, and that cartridge is much more popular than the 30-06 for long range shooting. The more efficient case and/or shorter action are generally cited as reasons for slightly better accuracy, but then the 300 win mag is also used with regularity when going long. The ratio of diameter to case length is much closer to the 30-06 than the 308, and it's obviously long action.

So why does the 30-06 have the reputation for not being as accurate? What do the 308 and 300 win mag have that the 30-06 doesn't?

Thanks and looking forward to the replies.
