To the heart and lung area of your favorite big game animal..NONE..the hundred or so feet per second isn't even worth talking about.. however I do beg to differ with all that talk about the short one being more accurate..I've owned a few long ones that amazed me at times off the bench and I've never owned a short one that really shot worth S---...must be me.

Wow.
 

Do a search...... this topic has been around the block so many times..........

As others have advised, the 308 Win. is a fine round for medium game hunting. I own and have hunted with many different cartridges over the past 47 years. too many to mention here. My favorite has been and clearly is the 308 Win. The 308 Win. cartridge is pretty much ideal for bullets in the 150-168 gr. range. Don't get me wrong, the 30.06 Spr. is without a doubt one of the all time great hunging cartridges. You won't go wrong with either. If you hunt bigger game that would require a hard hitting 180-200 gr. bullet for a clean kill, then of the two, go with the 30.06 Spr.

Yea you would think that but its not the case. Kind of suprised me too.

My chronograph has never shown these results. A friend of mine spent a whole summer with his .308 and his .30-06 pushing 150 and 165 grain bullets with every available powder. He used his two .308rifles ( a Remington and a Winchester) his Remington .30-06 and my Winchester .30-06 and filled up a log book with his results. He started with 200 new pieces of brass (Remington and Winchester) for each rifle and discarded them after 5 loadings each - at which time he put new brass from different lots into use. Using my chronograph he always noted higher velocities from the .30-06 rifles and better accuracy with the highest velocity loads from both .30-06s. The .308s were very accurate rifles but only really showed it with their mid velocity loads. Overall he found tighter groups with his .308s than with the .30-06s (but not by a significant amount) and higher velocities - and most importantly higher usable velocities - with the .30-06s.

The Nosler book I have shows it mainly with 150's and under. Im just using the information "Nosler" printed.

Were they the exact same rifle?

I have noticed many differences between reoalding manuals and real life.

The rifles uesed were:
M700 - .308 and .30-06
M70 - .308 and .30-06

True. not sure if a test on 4 different rifles proves it the other way either. Most of the reloading books I have print the higher pressures in the lower weight bullets in the 308 is why it out does the '06. Specifically with the "sporter" barrel length guns. I guess 80-100fps doesnt make much difference in the real world anyway. A warm or cold day could change it that much.

No, they both wish they were .270s :)
