Home Forums Reloading Varmint Rifles 6mm Creedmoor / 243 Winchester

The 6mm Creedmoor and the 243 Winchester....
Co-joined twins separated at birth???
So is there any measurable difference?

No, except that you can buy really good factory LR ammo for the Creedmoor, and slightly better barrel life.

I was always in favor of, " because I can..." The fun factor.

Buy both - isn't that what rifle loonies do?

Yes, that's true, and you're evil.....👍

If all 243's came with a 9 twist there'd be few that would upgrade to a 6mm Creedmoor, because 243 ammo is everywhere.
But the Creedmoor's 8 twist beats the heck out of a 10 twist 243 in versatility.

That makes sense. It's the same reason why I like a 1:8 on my 22-250

I wore out the barrel on my Dakota 243 so I rebarreled to 22-250 with 1:7 twist.
Now that Barret Fieldcraft is out in 6CM with 1:7 twist, I had to go for it.

I just received a 6mm Rem barrel with 7.5" twist. Should shoot the long ones well.

Cliff,

I have a one in 7 twist barrel, that I chambered in 6mm Rem and put in on a long action Remington.

RL 19, pushes 115 grain Bergers at 3250 fps MV...

105s bullets in excess of 3300 fps...

definitely a long range flat shooting cartridge.. bullets seated to mag length in the Model 700...

only regret is that I put it on a Long Action Remington instead of a Long Action Model 70....

24 inch Pac Nor barrel...

John, thanks for the info on loads. Mine is on my Blaser R8 and I'm using a 7x57 magazine insert so I should have no issues in seating my bullets out to where they are the most accurate. I've not used RL19 on my 6 Rem before but will certainly look hard at it.

Cliff another thing I'll pass on...

my most accurate rifle is that 6mm Rem...

and its most accurate load was a charge of H 414, with a 75 grain Hornady HP..

sadly discontinued, to make way for the 75 grain V Max, which isn't as accurate at all...

Speers and Sierra 75 HP are more accurate than the V Max...

MV was in the 3600 fps+ range...

Thanks John. H414 has been a favorite powder of mine in the 6mm for a long time. I still have a couple of hundred 75 grain HP's. I think the Sierra is a good choice, too.

If only they had come to market with a LH model...I'd have a stable of Fieldcrafts.

All this new stuff... Ruger Americans, Field Craft etc...

beginning to think I'm the only guy around who is still happy with a good old Model 70 any day of the week...

but me,and Ruger 77s

and Weatherby Vanguard/Howas get along pretty well also...

I'm even enjoying some of the Model 700s I have, once Redneck has done the bolt handle pinning job
on them....and I don't have to worry about them coming off anymore....

but then hey... I'm the kind of guy who likes old style bullets.. like Round Noses...etc...
so what do I know???

I agree and think the 6 Creed is the slightly better mousetrap. I expect I'll own one, or more, in the future.

That said, there isn't a lot of difference in performance, and you can purchase 243 ammunition in practically any small town. I don't think that's possible with the 6 Creed yet. The ability to find 243 ammunition almost anywhere is a big deal if a hunter forgets their ammunition and leaves it at home.

I had a hunter leave his 6XC ammunition at home one year. He had a backup rifle and had remembered that ammo, but otherwise he was going to have to borrow a rifle, which no one wants to do on a big hunt. He's a friend and I've teased him some, sort of, saying a 243 reamer would probably clean up the 6XC chamber.

Looked at a brand new Stainless 700 ADL .243 with the jeweled bolt and the black tupperware stock and 1:9 1/8" twist today. It felt light and handy enough even with 24" barrel, fit and finish was pretty good, the stock was slender and sturdy and appeared nicer than a lot of cheap rifles, and the matte stainless finish seemed smoother than what I remembered as more of a rough sandblasted finish.
I'm pretty sure that it would work with 80 to 105 grain bullets, which is all I'd really need.

I'd have a hard time looking further or fretting over it not being a 6 Creedmoor since I already have a pretty good supply of .243 ammo and seem to have some sentimental attachment to this 60 year old cartridge that has benefited as much as just about anything from advancements in bullets.

Also kind of attached to the 700 as it was my first centerfire rifle, although in a blued and walnut 30-06 BDL. They just seem to fit me really well and always feel just right in my hands, especially this lighter weight version.

In the end, I don't think I'd be missing out on anything with this choice.

Now just imagine it with a new spider web paint job......
Ok, I can shill for my own stuff 🕸🕷

Go ahead and get the Creedmoor

I didn't spider web mine.
Factory 80 gr are at .75" at 100 yds.
Haven't worked up any handloads.
Just a yote popper.
My prev ADL synth was .5" w 70 gr Nosler BT on max charge of 4350.
