Is There a Better Cartridge Than 308 WIN?

[Muddyboots]

Fired from a 20" barrel? For general distance use? Anything more efficient.

300WSM?

I thought that the answer to ALL ballistic questions was "6.5mm".

Mr @BFD 2.0 …tell us what you want this efficient rifle to accomplish. What distances must it be capable of? What will you be shooting with it? What is meant by efficiency? If it's the most power per grain of powder burned out of the shortest barrel the old .358 Winchester will smoke it's parent cartridge.

There is no best round.....

Define the mission of the round and parameters (price/availability/ranges/etc).

.308 is one of the greats and probably wont go away for a long time, that doesn't make it the best.

It is...but this is much more fun...

Shooting a .308 is like riding a Moped .

or driving a PRIUS!!! LOL

If going to use the .308 Win case??????
Go with a .260 Rem!!!!

A 308 Win would be from the gasoline era. Is there anything better than a 50 cal? Yup a 17 HMR when dumping gophers near irrigation lines Carry on with the mayhem lol.

Thanks Calvin, typo, changed to 8208...magic pixie dust for those two bullets.

Ya see - I told ya the answer was "6.5mm". LMAO

Doesn't the 7mm need a longer barrel?

You do realize the 7/08 is a necked down 308. Why would it need a longer barrel?

 

[Calvin45]

How on earth do you cram enough 7828 into a .308 to make a "hot load" with a 175 grain bullet???

Never mind…I see it's 8208 now. I was legit curious tho haha. I wanted in on the drop tube technique one would need. I've had some interesting results in using powders I'm told are way too slow to good effect (rl25 and 7828 in a 270 for example). But the .308 just seemed impossible.

You do realize the 7/08 is a necked down 308. Why would it need a longer barrel?

Because it's a smaller bore diameter. "Need" is a funny word…but all things being equal, from equal length barrels with equal capacity cases the one with the larger diameter bullet is more efficient. Generates more power. And wouldn't require as long a barrel to realize it's full potential becuase the total cubic volume for powder to burn and gas to expand is is much greater.

Extreme example but think 257 wby vs 458 win mag. Both based on a 30-06 length h&h case. Which one is more efficient as in powerful per grain of powder burned? Which one do you think would really benefit from a 26+ inch barrel more than the other?
