What round is heavier

[texaswoodworker]

They're both about the same. Surplus 7.62 bullets are about 147 gr, and can go over 200 gr (I think 203 gr), and the 30-06 bullets can go from 110 gr, to about 240 gr. 30-06 is more common, so there are more ammo choices.

The .30-06 is also known as the 7.62 X 63. It is 9mm longer than the Russian equialent. The base of the Russian round is larger. I consider the X 54r to me more on par with the 7.62 X 51 NATO as far as power.

Russian long cartridge = 7.62x54mm Rimmed.
Russian short cart.= 7.62x39mm rebated?
The Russian long cartridge is powered between the .308 and the .30-06.
it is a very powerful round and now they(Sierra or Hornady) make .311 cal. 168gr. HPBT match bullet now so it improves the accuracy.
They are as accurate as the gun/shooter.
All if the above can be reloaded up to heavier bullets, so the Russian Long can be made as powerful as the lower versions of the .30-06. much like the .308.

Today it should not as much about bullet weight as it should be about bullet construction. Just a better choice of loaded ammo for the 30-06 For a hand loader ? They both are fairly close to the same level with better rifle choices in 06.

If you look at original data:
7.62x54r: 147gr, 2886fps. 185gr, 2660fps
.30-06: 150gr, 2740fps. 172gr, 2640fps
The walls of the .30-06 are strait to the bottleneck. The x54r are tappered. Is it possible that the tappered cartridge could have better velosity, sure it is. Even though it is shorter. Similar to the Short mag theory today.


You can handload the x54r to over 2900fsp w/ a 150gr bullet and modern powder. But again, so can the .30-06.

.30-06, 7.62x54r, 8x57, and .303 Brit were part of an arms race in the late 1800's, early 1900's. The U.S. cartridge was the last to come out w/ a spitzer bullet in 1906.
All four are on par w/ each other w/ the .303 bringing up the rear w/ an original militay load of 174gr bullet at 2450fps. This had more to do w/ the strength of the action then the actual potental top end of the cartridge.

The 7.62x63 is a better round & can be loaded a lot hotter than the 7.62x54R.

just use 7.62/59 which in the us is .308 its good round.

Please explain why. That's like saying Blondes are hotter then Redheads.
