What are the velocity of the muzzle, feet per second (FPS) and the yardage of the .308Win and .30-06 Springfield? Your response will be greatly appreciated. Thanks. :)

Introduced by Winchester as a new sporting cartridge. The .308 is nothing more than the T-65 or the NATO 7.62X51mm military round. The Model 70 bolt-action and 88 Lever action
Winchester were the first American sporting rifles so chambered. It was adopted as the official U.S. military rifle cartridge in 1954, although weapons for it were not ready until 1957. The factories used a special ball-type powder in loading the 308, and it was difficult for the
handloader to equal factory ballistics with the powders then available.

In Power the 308 Winchester is superior to the 300 Savage and almost equal to the 30-06. It delivers about 100 fps less muzzle velocity than the larger 30-06 with any given bullet weight. Most authorities consider the 308 suitable for MOST North American big game, although it's on the light side for moose or big brown bear.

NOTE: The 30-06 is a slightly-modified version of the original 1903 cartridge, which was loaded with a 220gr round nosed bullet at a muzzle velocity of 2300 fps. A change was made in 1906 changing the bullet to 150gr and the case shortened by .07", with an increased velocity of 2700 fps. The 30-06 can be chambered and fired in any rifle made for the 1903 round, however, the opposite is not always true.

As indicated in the "Other Names" category the initial Springfield round was designated 30-03 Springfield, and with the modification in 1906 the designation changed to Ball cartridge, caliber 30, Model 1906. As with most all military regalia, the name was shortened to 30-06.

Also located in the other names section, the round was called the .30 Government. The original .30 cartridge was designated the 1903 cartridge, the year it originated. The modified round was designated the 1906 ctg., the year it was modified, with the modified name of 30-06. The first two digits, 30, indicating the caliber of the cartridge, the 2nd two digits, 06, indicating the year of modification.

This designation was necessary as they were limited in the firing of both cartridges as one should not be interchanged with the other in the same rifle. The -03 produced very poor accuracy in the -06.

Thanks, Harley Nolden for the valuable info. Just wanted to know before I purchase a bolt-action rifle. I still want to know the yardage. :)

ED:
I have found that for greater distances the .308 surpassed the 30-06. Now I am not an ammunition expert, I only know what worked for me.

Using a machine rest, sand bags and prone, sling supported, the .308 with a 168grn, Sierra Boat tail was great even at a grand. You'll probably find that the Bolt gun will provide uniform chamber pressures as opposed to the auto guns. This has also been an experience of mine.

Marrying ammunition will enhance the accuracy of any gun. I have found that if I had a Winchester Gun, Winchester ammo did well. But mostly Federal was the best of the factory stuff. Special loads, made by a competent reloader were the best, and after testing the least expensive.

Not sure just what you mean by "yardage," but I shoot the 308 at 1000yds on a regular basis and it works fine with the correct bullet. I use a bolt gun as opposed to the M1A service rifle, but the Sierra 175's or 190's work quite well at that distance. I will say that 1000yds is about all the 308 wants, for it drops off from there quickly and not much you can do about it for you can only stuff so much "go power" in that case.
30-06 probably could go a bit more, but in reality 1000yds is pretty much it for these two rounds. 300WinMag better choice for extreme ranges, but you pay a price for that extra performance in terms of recoil, barrel life, cost to reload, etc., but it does outperform the 308 or 30-06 especially with any wind kicking around. I am sure there are other opinions out there, but the above is what I have found with my experience.

No argument with any of the above, but there is a vast difference between punching paper at known distances and practical maximum ranges when hunting.

Both cartridges have similar trajectories. If you're guessing at the distance from you to a deer, and you're not all that experienced, I'd call either cartridge a 300-yard deal. That is, if you are zeroed at 200 yards, you're 2" high at 100 and 6" low at 300. "Point it and pull" will hit a deer in the body...

It's like anything in the world of guns: What do you plan to do? Casual target? Serious, competitive target shooting? Hunting? If you hunt, do you sit in a stand, mostly, or walk across open country? Do you plan to get into reloading?

For instance: I've been shooting a .30-'06 for 50 years. I've had my 26"-barrel rifle for about 30 years. I reload. I'm mostly a "walking hunter". The package I've put together works better for me than, say, a 20" .308 would. But that's me. Different deal for you, maybe, might mean the .308 would work better for you...

So do some more thinking before jumping onto any rifle. Little stuff like sensitivity to recoil, for instance. You might be happier with a .243--who knows?

Don't be in a hurry...

Have to agree with Art.

My 30-06 load is a sierra 165 gr game king spitzer boat tail soft point pushed to about 2800 fps. You run about an inch an a half high at 100 yards, zero at 200 and drop 7 inches at 300. 300 yards is about my maximum range for a 1 shot kill (in the field real conditions as in wind, weather, terrain etc) though I've TRIED to shoot farther than that at a wiley Buck Antelope. ;)

Federal Premium 165 grain ammo will do the same.

Remminton commercial 150 grain ammo will do nearly the same but with a velocity nearer to 2900fps and a +1.7/0/-6 inches at the same ranges.

180's will run more like +2 to 2.5/0/-9.5 and travel at around 2700fps.

Bottom line is if you can SEE the deer/elk antelope, put your sights on the kill zone and squeeze the trigger, if you THINK its out near 300, hold HIGH ON THE BODY, not OVER it.
You should STILL put the bullet through the vitals.

Art, I planning to reload my own ammo, go hunting for bigger game, and I am a walking hunter. It just that I am a .30-30Win reloader and hunter. And I am trying to go for a bigger bullet and bigger game than the usual white-tail deer. :)

Ed: Okay. Here's my opinionated opinion: I prefer the '06 over the .308. I bought my 26" barrelled gun on purpose, planning on getting the max out of my reloads.

Anyway, factory loads in the '06 are loaded to 47,000 or 48,000 psi, as I recall, because of the older guns. The .308 is loaded to around 52,000 psi. So, handloading the '06 to 52,000 psi lets you outdo the .308...

In a recent comparison test at 400 yards with a 90-degree wind of some 15mph, I held one foot less windage and one foot less elevation with my handloads in my '06 than with my friends 20" .308 with GI ammo.

I prefer the boat-tailed bullets. I have used 150-grain and 165-grain on whitetails to good effect. The 165-grain and 180-grain oughta do just fine on elk, from what elk-hunters with far more experience than I have posted here. Again, skill level and judgement play a large role as to one's success.

At any rate, have fun!

Thanks Art. Looks like the 30-06 it is. I like the round in my M1-Garand anyways. But I always wanted to buy a .308 rifle ever since it came into the market. But I guess my choice is the 30-06. Thanks again Art. :)
