Uhh, the 30-06 does kick more, I have a Mauser 30-06 that weighs a few pounds more than my Mossberg 308 and the -06 definitely has more kick shooting the same grain bullet, both have nice cushy pads on them so it don't matter to me.
and lastly all the powder that is going to burn in a rifle cartridge will have done so in the first few inches of bbl if the opposite were true rifle caliber handguns wouldn't work at all. As evidenced by the fact that the fastest loads for a 24" rifle are still the fastest loads for a 14" encore handgun utilizing the same powders
Really? Is that why the military is having so much trouble with the M-4 developing enough velocity for the 5.56 round to fragment properly?
I wish people wouldn't keep distributing these same old tired internet myths....

And the 30-06 does use slow powders...so do all of its offspring (25-06, 270, 280, etc), and they need a longer barrel to get up to speed...we've had this argument before...
Granted, I'm comparing different rifles of different weight here, but according to my Lee shooter program, the recoil difference between the 30-06 and .308 is significant. In my dad's 7lb Browning 30-06, with a 165 grain load, it shows 20 ft lbs recoil. In our Remmy 700 tactical, 20" heavy barrel, .308, which weighs in at about 8 lbs, it show's a recoil energy of about 16 ft lbs.
That's right at 20% less recoil energy.
By the way, when I shoot both of these rifles, I can definitely tell the difference. 20 rounds from the 30-06 and my shoulder is feeling it. 40 rounds out of the .308 and I'm still doing fine.
any reason to chose one over the other
