.30-30 vs. .30-06

[Tyman]

which is better?

[JSnover]

The '06 is a much better big game cartridge. The .30-30 has been used on moose and bear but it's not the best choice for large/dangerous animals.

30-06 is 2 to 3 times more gun than the 30-30

The .30-30win developes 1900ft lbs with a 150gr bullet. The .30-06 developes 2820ft lbs with a 150gr bullet,that only somes out to about 1/3,d larger.With the same bullets the .30-30 leaves rhe muzzle at 2400fps.the .30-06 leaves the muzzle at about 2900fps.That is 24/29ths.Not all that much. Where the 06 has the great advantage is the spire point which carries fps/energy much further than the flatpoint or roundpoint,s in the .30-30. sam.

inside of 100yds, no animal will ever tell the difference. past 100, the -06 has a decided advantage.

Hi Samuel
On thing to consider is that the equation that shows energy is 1/2mv^2 meaning of course is that as the speed is doubled the energy goes up 4 times. So 2900^2/2400^2= 1.46 or 46% more energy.

My wife shoots her 30/30 well. The 30/30 is usually a 150g @2350=1840 ft pounds . Her mosin that she usually shoots has a 183 g @ 2600 for 2750. About matching your number.

Of course I am ignoring the effect of an aerodynamic bullet down range but am measuring near muzzle energy.

I am glad that you pointed it out (pun) most people ignore aerodynamics which play a big part in ballistic performance.
Good post
