jumping into the world of precision shooting and trying to decide
caliber. We have deer rifles in .308 but it seems the newest craze is 6.5 creedmoor?
-I'd like to eventually shoot 1000 yards.
-I am able to reload for either caliber

Which one?

308 just because every newbie who jumps into 6.5 c is making it next to impossible to get brass or loaded ammunition

I am sure most people would tell you 308 but I have had great luck out of my 6.5.

.308 is a great round but 6.5's are where all the time, money, and research seems to be going...well, bullet diameters from .260 to .290, anyway.

If I were starting out with long-range shooting and wanted to shoot 1000 yards, I'd go with 6.5, hands-down.

7.62 can do it, but it won't do it as well.

It's true.  The worst thing to happens to small arms in the last century was the insistence to chamber rifles and machineguns in .30 caliber.

Meh.

Bolt gun = 6.5C
Semi = .308WIN

Different applications, IMO, for starters.

The fun part of the arguments start when the 260REM and 6.5C guys start fighting.

You do realize CM work perfectly well in a properly built semi-auto, right?

Secondly outside of single feeding the .260 in a bolt-action the is no advantage to using it vs 6.5CM.  Literally it comes down to a .7 grain difference favoring the .260 and you have to shove the bullet into the powder collum in order to get the 260 to fit into a magazine.

6.5mm is "happening" right now. Like its been mentioned there is a ton of loads, equipment, new products, expertise, being generated on it. Not just that but also ballistically the 6.5s are better. Better BCs, less recoil, short actions, and longer lives on barrels. As a young hunter I was always suprised the 6.5 Swede didnt have a larger following on this side. It was, and is, an excellent hunting cartridge and has been around a long time. I see the 6.5s really taking off even more in the future. If you get a good deal on bullets or brass I'd stock up.

Same loads, drift over 1000 yards at 10mph wind.





My opinion: .30 works.  .30 can be accurate.  With the data and practice from 1000 yards and less, you can do just about anything with .308 that you can do with a 6.5, but 6.5 makes it easier to do with a lower margin of error at lower recoil.

LRRPF52 and DeltaElite are both correct, actually.  The US took the lazy way out and then after getting other countries to sign onto using the .30 cal the US then dumped it for the 5.56...

So you used one of the best bullets for the 6.5 and one of the worst bullets for the .308?

We use scopes with elevation knobs  for a reason, dialing drop.

I used the last .30 cal bullet I used.  I'd be happy to chart whatever projectile you'd prefer to see.  I'd much rather dial 28 MOA than 41 MOA myself.  Since I quit loading for .308 for anything but hunting, I used FGMM because the velocity is available and last I knew it was considered a standard.  Give me a projectile and muzzle velocity you feel is more apples to apples and I'll chart it.

Yep.  The Germans had the excellent 7X57... fucked up and adopted the 7.92x57.  The Japanese had a superb little 6.5 cartridge, fucked up. and went with the lackluster 7.7.  The Garand in .276 would have been even better than it was.  The .30 Carbine round necked down to .22-.25 would have been a world beater.   The Germans again fucked up the intermediate "assault rifle" cartridge buy insisting on a .30cal bullet (That cartridge with a 6-6.5mm bullet might still be in use).  The Soviets did the same thing with their version of it....

Spit the best .308 bullet out as fast as you can, and an 18" 6.5mm will beat it for wind drift still.

The biggest thing you see shooting long range is how the higher BC pills just don't like being pushed around by the wind like they do to .308.

Trajectory of the .308 is like a small mortar in direct-lay mode.  I have watched both side-by-side for well over a decade now, after the previous decade of watching mostly .308 and .300 Win Mag through the spotting scope, so when you get behind the 6.5mms, the first thing you notice is flatter trajectory and substantially reduced wind deflection.

For bolt guns, at least here in Utah and the West, I'm seeing a trend where 6.5 Creedmoor has become the new baseline long range cartridge.  There are still plenty of .308s out there, but we're finally catching up with what the Scandinavians knew in the late 1800s already with 6.5x55, and Brits and others discovered in the early 1900s with that and 6.5x54 M-S.

What barrel length are we using? My loads are all from a 20" bbl. so it wouldn't be fair to compare to the superior 6.5 with a 24" bbl.

I will give you 20 fps per inch, which I've found to be an accurate estimation in that velocity range.  Or I'll take it away from the 6.5 whichever you prefer.  So +80 fps to your MV or minus 80 from mine.

After I chart, if you have the data I'd be curious to see if your real world POI is +/- where I'm calculating it would be.  So lets take 80 FPS away from the 6.5.

You know, I've heard you can make 6.5C from .308 brass.

It's not really worth it.

Sell the .308 brass and buy Winchester box ammo for 6.5 Creedmoor.

That brass is awesome.

Yeah that 300 Norma Magnum is a piece of shit....

There's nothing inherently wrong with a .30 cal round. I own two custom rifles LongRifles Inc. made the 308 and a diffeerent smith made the 6.5 creedmoor. Both are hammers and the Creedmoor is definitely easier to shoot at distance as it bucks the wind more.

However, the 308 has 3x the barrel life and really the 6.5 Creedmoor outpaces the 308 at the outer fringes of where most people shoot.

If you want to shoot 1,100+ yards regularly or shoot in PRS matches, go Creedmoor. If you're shooting less distance regularly or not in a competition environment there's nothing wrong with the 308 and you can walk into most stores and buy match ammo off the shelf.

People seem to forget there's been a lot of advances in ballistics over the years AND advances in smokeless powder.

So you used one of the best bullets for the 6.5 and one of the worst bullets for the .308?

We use scopes with elevation knobs  for a reason, dialing drop.


I used the last .30 cal bullet I used.  I'd be happy to chart whatever projectile you'd prefer to see.  I'd much rather dial 28 MOA than 41 MOA myself.  Since I quit loading for .308 for anything but hunting, I used FGMM because the velocity is available and last I knew it was considered a standard.  Give me a projectile and muzzle velocity you feel is more apples to apples and I'll chart it.


What barrel length are we using? My loads are all from a 20" bbl. so it wouldn't be fair to compare to the superior 6.5 with a 24" bbl.


I will give you 20 fps per inch, which I've found to be an accurate estimation in that velocity range.  Or I'll take it away from the 6.5 whichever you prefer.  So +80 fps to your MV or minus 80 from mine.


OK, that is fair. My 230otm(g1 .719 /g7 .368) load is 2397fps(47.7gr w760 3.245" oal)

Now of course the danger space will be reduced due to drop but wind drift  won't show the huge difference you 168 chart shows.


Obviously too long for mag feed but I am target shooting ,I  have time to single feed

Is that a Sierra bullet?

ETA: I'm not in any kind of competition vs those who prefer .308.  I'm only interested in the data.  The more data the easier for others to make their own decision.
