    What are the pros and cons of .308 Winchester and .30-06 Springfield?

    IMHO, from a handloaders standpoint, one is simply a short action version of the other... That being said, the .30-06 will better handle heavier bullets, buuut the .308 has the advantage of a lighter more compact shooting platform. A piece of paper 1000 yds is in just as much danger by either one when properly loaded ammo and a properly equipped shooting platforms are employed (i.e. a NM M1A vs a NM Garand with DCM approved ammo for both) Like wise for deer out to 600 or 800 yds if you can shoot that far;)

    Well lets say for instance we have two identical bolt guns,same maker,action and barrel length. Now we load up a MAX rd. for each using same primer, IMR-4895 and use a 168 gr. BTHP match grade bullet in each load.

    Here is what you end up with (data taken for Lyman #49 manual),the 308 MAX load is 42.5 grs. of 4895 MV is 2624 fps,pressure generated with that load is 51.200 cups. On the 06 MAX load is 48.5 grs. MV is 2762 fps. pressure generated is 47.600 cups.

    As you can see the 308 takes less powder,works at a higher pressure but only gives up just a slight bit of MV to the 06. The 06 as stated gives you an advantage in the heavier bullet dept. over the 308. As JLA stated at 1000 yds. punching paper or anywhere below that at normal hunting ranges it just comes down to personal preference more than anything else.

    Before last month, I was a die hard '06 fan, but about a month ago I bought a .308 I have found out That I consistently fing accurate loads for the .308 as opposed to the '06 . I have almost decided that the .308 , under normal circumstances(not using a 200+ gr bullet) will do as good as a .30-06 in almost all catagories, with quite a bit less recoil.

    I have both...if you are going to hunt, they will both do well, but the 06 will take down anything in North America...it has more versatility in loads using all different weights of bullets. Your choice

    FTK does have a good point... However I personally prefer the 06 to the .308 due to the exact reasons jdon mentioned about load versatility...

    308 surplus is "IMO" more available as it is the current NATO round

    i have a .308 and love it. from my reloading books there is not much of a difference between the two. The 06 can haul a slightly heavier bullet but either way both caliber are great!

    The case capacity of the 06 is far more than the 308 and as such the 06 will do more than the 308 no matter what like weight bullet one chooses to use. It is exactly like cubic inches in an engine, the more inches the more power. As for 1000 yard shooting I don't think there is a 308 loading that is still going supersonic and there are many loads in the 06 that are. res45 with his loading data gave some insight to one issue that plagues the 06 and that is there are a lot of guns out there chambered in 06 that cannot take 55,000 psi loads. The lever action model 95 Winchester as one example and as such most factory 06 ammo and reloading manuals stay very conservative on pressures due to liability problems. The reason a 308 does not recoil as much as an 06 in like a rifle of the same weight, is because the 308 is not doing as much work (the bullet is not going as fast) as the 06.

    For deer and black bear hunting, as well as other animals of about the same body weight both are adequate but the 06 will give you about a hundred yards more range. For elk, big bear and moose the 06 with 200 grain bullets would be my pick at any range way over any loading in 308.

    "What are the pros and cons of .308 Winchester and .30-06 Springfield?"

    I reckon part of the answer really depends on what is your intended use for the rounds?

    Hunting (what?), target shooting (at what range?), only from a reloading perspective?

    As noted in the lates Speer manual, there is new news for the comparison of these two calibers. Before, when the max pressure for the '06 was 50kpsi & .308 was limited to 52kpsi the '06 won out on velocity in light & heavy bullets both. But now that the .308 pressure limit has been increased to 62K psi the .308 throws bullets up to 150 grains noticeably faster than the '06. The nod still goes to the '06 for bullets heavier than 150 grains. This will be for new loads developed with the 62K pressures. If you dare to work up loads till pressure signs develop & back off slightly I would guess the '06 would win out with all bullet weights, but new listed loads will now be showing the .308 as faster with lighter bullets.

    After reading all these responses, I have a question. If you have a lighter rifle with more pressure vs. a heavier rifle with less pressure, how would the recoil compare if both are loaded with the same weight bullet?

    The preferred bullet for my 30-06 so far is a 190gr SPBT. My twist is too slow for the larger bullets I've tried. I can hit pretty accurately but the bullets will not stabilize. I was shooting some 220 gr RN a few days ago and all the holes in cardboard were oblong, you could clearly tell the bullets were wobbling in flight. I think that would effect the velocity greatly at medium to long distance, when I hit steel, [at 300 yards,] they didn't dent at all. I also tried to use the 208gr A-max and had the same issue. So twist rate has a lot to do with it also. A 200gr bullet just might work in my rifle but it is most likely right on the border.

    It is a much larger issue than simply comparing one cartridge to another. There is much more of an exacting science to it.
