What would you say are the most efficient medium bores in barrel lengths of 20" to 22"? What I mean by efficient is most powder burn and least effected velocity, not cost of ammo. Thanks! Gary

In a 20-22 in my OPINION when you get larger than a 06 type case you are going to have trouble burning the extra powder in the barrel. So before
30-06, 338-06, 35 Whelen, 9.3x62 375 Whelen

I know Ruger is sticking the 416 Ruger in a short barrel. Do bigger cases work sure but you burn a lot of extra powder for the gain you will get.

35 whelen comes to mind.

For shorter barrels it's hard to beat anything in the 308 family, 7mm-08, 308, 338 Federal or 358 Win.

Gary,

Not sure what promted that question, but just a thought of caution:

I've never bought a rifle or picked a cartridge because the barrel or cartridge case was "EFFICIENT"!

Now, I do have a 308 and a 303 with 20" barrels because the concept of these rifles are "COMPACT".

Ray, You hit the nail on the head. I like shorter, compact rifles and was trying to pick everyones mind for caliber. First thing that came to my mind was a 308. Trying to think outside my box!

Id say 308 also. Never wanted one till I got a killer deal on a '53 m70 featherwight in 308 winchester and started reloading and shooting it. Now I like 308s alot

I think the 358W wins hands down for energy with least amount of powder! Good enough to take moose at 200 meters.

+1 for the 358 Win. They don't make 'em any more efficient.

I DO Lou !
.375 X 41, 300 grain gas checked bullet at 2150 fps.That's 30-06 energy level with 36 gr. of powder. Now what practical purpose do we have with these larger bore efficient cartridges? roger

22short!

Not if the shorts cost as much or more than the LR. That's when you can get em. or have a rifle to use them in. roger
