Re: 30-06 vs 300 WSM vs 300 Win Mag look at these numbers

Thanks for the comparison. The venerable 30-06 is by far the most efficient of the group.

I ran some data using a long barrel, modern chamber 6.5x55 with a 140gr Berger VLD G7=313 @2750fps. It did a bit better at 600 than any of the three 30 calibers...but only to 600.

The 168gr 7MM Berger G7=.316 running at 2950fps puts them all in the dirt at 1000.
The 180gr 7MM Berger G7=.345 running at 2900fps leaves no doubt as the the superiority of the 7MM bore size over the 30.

Guess that's why the .284 and .264 bore sizes have been showing up with higher frequency in the last few years.

Fair point but that raises an important question:

Which of the 6.5/7mm rounds match the efficiency of the 30-06? If it is the .30 to beat which 6.5/7mm does better without being a barrel burner?

If you're going to use bullets in the 140-180 range, then I would go 6.5, or 7mm. In the .30's my preference is 200 grains and up.

I think the .300 Winchester has been proven world wide, and is the "standard" this class is judged by. That's not to say other cartridges don't compete or have merit. If you look at the various platforms, and settings it's been used successfully in, it can't be left out of the discussion.

Relative recoil is a legitimate factor to consider.

I agree. The thing about the tried-n-true calibers like the 30-06 and 300 WM is with the tremendous advances in projectiles and powders both can shoot beyond the levels that existed when they came out.

Your data is obviously faulty. The 300 WM enjoys a minimum of 300 FPS velocity advantage over the '06. Therefore, your drops are not correct.

You are showing a 15% diff in drop, when in real life, the diff is 27%.

So, you might want to rethink this one.

I suppose those drops could be true depending weight of bullets etc. for example a 150 in the 06 could be over 3000 and a 300 with 210 could be 3000

It could be but he stated that he was going to use a 180 gr bullet for each one. His numbers are off quite a bit. There is no way the 30-06 will push a 180 gr pill close to the velocity of the 300 WM.
