I like both

Which cartridge do other members consider the most useful and versatile? And why?

.243 or .308

My 2 cents.
Aside from livestock, the largest game animal or varmint in my area is whitetail deer and feral hogs. Both easily taken with a .243. Terrain, being relatively flat and open, dictates some long shots. I do try to limit myself to 300 yd on deer. A quick clean kill means less gamey venison.
Varmints and hogs? I just take the shot, 400 yd with VERY minimal elevation adjustment.
Obviously, the .308 will do very well. I just don't see the need for a 150 gr bullet and the accompanying recoil.
That being said, If I ever have the opportunity to hunt Elk or such. I either borrow or buy a new gun.
Geography and indigenous prey led me to opt for the .243.

I'll go with .308

only because I don't have any experience with .243. Honestly, I've only shot a .243 rifle one time. I haven't been deer hunting too much, and when I have, .308's and 30-06's always did the trick. I know the .243 has a flatter trajectory, I just don't have much first hand experience with it. the .308 is a more common round, therefore I would rather have a rifle chambered in it because the world will go to shit within my lifetime. What about the .260? I'm also starting to like the 6.5 creedmoor by the numbers

oh...I know its off topic, but besides the recoil, .300wm kicks ass

Naw, hell I don't know as I don't own anything in either caliber. Like Vaq
said, I guess it depends on what you are trying to drop.

I'm with Reaper for several reasons. I have owned and shot others .243's and it is a fine cartridge. Great for varmit. My favorite for groundhog was a 6mm though. (1)When the world goes to shit I want to know that i have a gun that will feed on what is on the ground or attainable in storage or by alliances. I have 1500 rounds (shoot or trade) for an AK i don't own yet for that very reason. The HK41 has plenty to feed on as well. (2)I also like the heavier bullet for the stopping capabilities.

Very flat & fast trajectory. Less kick for sure.
My old 66 yrd old eyes don't see that far very well anymore, So I will hire Obama in a couple of years and use him as a beater to drive the game in nearer to me. Since he will be looking for a job in 2012 or sooner.
I will put up ballistics of both if I can get them to work...

Something tells me

that your Obama beater wouldn't last long before there was an ugly

The guys that have done this conversion say that by using the Yugo 24/47 makes the easiest conversion from 7.92 to .243 as the .243 is a necked down .308.
9 out of 10 times the extractors work, rails are same size and only real change is new barrel and headspacing. Mag is same size. Griffith even makes a box mag that will work.
Of course I would put on a varmit thumbhole stock and some decent optics and a Timney drop in trigger ($49.00).

Projected costs;

Yugo 24/47 $ 140.00 JG Gun Supply in AZ
Stock 85.00 Found one on the forum
BBL 250.00 Shaw or Shilen bull bbl
Smithing 100.00
Trigger 49.00
$650.00 +/- Plus Optics, I have one that I can use off of another gun, not great but good.
What do you think?

Sounds like a heck of a decent rifle.

7mm-08. Middle ground, kinda.
You can get some pretty decent ballistics from these too.
Plus a wide bullet weight range.
I've seen some mention of 6.8 on some posts.
Might be a perfect balance of ballistics and knockdown.

The 6.8 is a relatively new cartridge, introduced in 2004, that was developed to fill the desire of various military units for a round that would allow heavier bullets to be fired in an M-16-type rifles. It is obvious that, as a minimum, the gun's barrel must be changed, but the conversion looks pretty easy. Based on the .30 Remington case, the 6.8mm Remington is considerably more potent than the .30 M1 Carbine and seems to be well suited to the assault rifle. Its actually slightly more powerful than the 7.63x39 round. Its ultimate popularity will probably depend on what rifle selections become available. Per- the 4th edition of Ammo and Ballistics.

is how close the two rounds are to each other, really. Look at those measurements. Nearly all of them are precisely the same, except the crucial one, of course. The whole base of the cartridge, up to 1,5598, appears to be exactly the same.

The .243 was developed from the .308 casing.
Same brass, different neck size.

Possibly the same Brass, but Not the same neck size, It WAS a spin off of the .308. The length on a .243 is longer than that of a .308/7.62 NATO. In comparison of the 6mm to the .243- The .243 is longer. But which the 6mm has a higher fps compared to the .243 by almost 100 fps. According to my book , the 6mm has taken over all middle ground between the .22s and the 7mm, except for the .25-06. Overall length of the 6mm, from tip of the neck to the rim is 2.233, and for the .243 it is 2.045. The width is the same @ the tip of the neck and @ the base of the rim-.276 (neck tip), and .473 (base/rim) base.

Read my post carefully, then read yours.
100fps at 3000fps+-, yep, sure is but the .243 is a short action mil issue action, the remmy aint, the twist rate makes the "factory" .243 more accurate than the Rem 6mm. I'm gonna copy and paste a couple of sentences, If you don't mind.
"The .243 is longer."
"Overall length of the 6mm, from tip of the neck to the rim is 2.233, and for the .243 it is 2.045."
Both from your keyboard.
ACE, I aint trying to be smartass or piss you off. You can run circles around me on anything but
.243, .357Mag or .38 Special. Those are my bread and butter.

They are both from my keyboard, and both out of my book.- 6mm Remington- Remingtons 6mm was introduced in 1963, as a replacement for a basically identical cartridge called the .244 Remington. Remington expected that the cartridge to be a formidable competitor for Winchesters .243, but their guns were built with a 1 turn in a 12 inch twist (vs. the .243's 1 turn in 10 inches). This left the .244 unable to stabilize 100- and 105- grain bullets reliably. In 1963 the caliber was renamed the 6mm Remington, and the rifles were manufactured with a twist rate of 1 turn in 9 inches. The sales of this cartridge must be sagging because there is little new activity from the ammo manufacturers. Not pissed @ all. And defonately dont think U R a smartass. I am typing word for word from my book, and thats all....

OK, I'm good with that.
However I stated the brass was the same, different neck size.
You stated same with a NOT the same neck size.
We do agree.

Kinda spendy for reading and research, but.
Get all of the reloading manuals you can find and afford.
It won't be "gun specific" but you will be amazed at the cartrige info and history found in these.
Look at pawn shops and book re-sell stores. Some of the intros to calibers were written by the men who developed these rounds and weapons.
In edit.
Sorry , I shoulda mentioned that they are published by the bullet manufacturers.
Speer, Hornady, Nosler, Sierra, etc.

So sam, is this

what you are doing with that Mauser action that you posted a day or so ago? Say didn't I read a post of yours that indicated that Mrs. samD had you on some sort of gun leash? It might have been a very old post IDK, I can't keep it all straight...lol
