30 calibers
 

Besides the amount of powder behind the bullet, what is the difference between the 270, 30-06, and 300?? Thanks in advance.

RE: 30 calibers
 

The .270 uses a smaller diameter bullet ( .277")...

The 30-06 and .300 Mags use a .308" dia. bullet and the main difference between them is that the larger case for the magnum holds more powder...More powder + same bullet = more velocity, which means more energy and a flatter trajectory...

The .270 also uses less powder, the average deer round is 130, while the average deer round in the .308 Win and the 30-06 is 150, and the .270's elk and moose round is a 150 grain, but the .308 and 30-06's standard elk/moose bullets are 180 grain.

(short sweet and overly simple)

270 is a necked down version of 30-06. Basically, or rather in simple terms,its the same cartridge but smaller bullet. 300 is the same diameter bullet as 30-06 with a different cartrdige, load, etc

From the deer's perspective, not a d@mn thing!

RE: 30 calibers
 

by "necked down" do you mean smaller projectile? The length?

RE: 30 calibers
 

smaller in diameter projectile

The 30 caliber does not automatically have more power. Power is derived from a combination of bullet weight and bullet velocity. The 30-30 is a 30 caliber but does not have the so called power of the 270.

I would suggest that if you are interested in this stuff that you purchase the Hornady reloading manuals where you will find about everything there is to know about calibers and ballistics.

Or... Check out the ballistics tables, free, at www.remington.com or www.winchester.com or www.federalcartridge.com .

You must not have ever seen the fear in their eyes when they look up and see a 300 WM pointed their way.
