Which is most accurate 7-08 or 308. Most tactical rifles are in 308 but is the 7-08 which is a necked down 308 not just as accurate and as deadly? It has better BC and has good bullet weights.
Any difference would be so small, that in the end, I suspect the differences in rifles and shooters are the largest error factors.
I was on the firing line when a Long Range champ bud shot a 200-19X at 500 yards with a 7mm-08. It will shoot well.
Lots of Highpower competitors were using the 7mm-08 in the mid nineties. But this is mainly an expression of the irrational, superstitious, herd mentality prevalent among many highpower shooters.
In the mid nineties the 7 mm 168 SMK had an ungodly high published ballistic coefficient.
Not only did the 7mm-08 shoot well, guys like Mitch Maxberry were winning National Championships with the things. Yahoo!
Then, Sierra reduced the ballistic coefficient.
The day after, tumbleweeds were rolling in 7milltown.
Still, the 308 is about the easiest cartridge to load match grade ammunition. Because of this, there are all sorts of dogmatic statements, over which is the best powder, (for example: "IMR 4064 is the most accurate") and the fact of the matter is, there are a lot of powders that do well in the 308.
There are a lot of good bullets in the 308. My favorites are 168, 175 and the 190 SMK's
