243 Win vs 6mm Creedmoor vs 6mm Rem

Any thoughts on these as long range target cartridges?

I like 243 because it's really common and if need be there is lots of factory ammo if I ever needed it.

The Rem has a slightly higher velocity typically. It is a nearly dead cartridge though so components are harder to come by.

The Creedmoor seems to have the fastest barrel twist rates (1:8 and 1:7.5) which is why it typically is loaded with 105-115gr bullets and the other 2 are usually 100 gr or less. Though since I would be reloading I can load them to wherever the rifle can stabilize. This is a new come and may fade out like the 6mm Rem making it harder to come by components.

Jury is still out on whether the 6mm Creed is going to take off like it’s bigger brother. I think it definitely has a leg up on .243 Win as it was designed from the onset to be a long distance target cartridge while the .243 Win was adapted to be a long range cartridge but that wasn’t the design intent.

This can be clearly seen on the SAAMI specs for the .243 Win which specifies a slower twist rate which isn’t good for stabilizing those heavier bullets needed to reach out. People have since chambered faster twist rate barrels in .243 Win and turned it into a target cartridge. As you have pointed out it isn’t hard to find factory ammo for, but you likely won’t find much of a selection of loads that are comparable bullet weights to 6mm Creed loads.

If your building a custom rifle .243 Win would be one to take a look at just from a component availability standpoint. An off the shelf rifle with a SAAMI twist rate is lacking when compared to the 6mm Creed.

As you said the 6mm Rem is a dying cartridge and I wouldn’t want to be the one to try and revive it.




Reloading...it’s like knitting for men.

I'm a big 243 fan. The 6 Creed, and 6mm, are pretty much equals, IMO. You MAY eek out 100 fps more than the243 with either of those cartridges, but 50fps is more like it. For the added cost of brass, the juice isn't worth the squeeze, IMO.

For the guys shooting factory ammo, yeah, the 6Creed wins, better ammo selection for long range.
And, there seems to be more off the shelf, long range type, rifles chambered in the Creeds.

IF I were building or rebarrelling, 243 every time.
By the same token, I'd go 260 Rem over 6.5 Creed, or 6.5-284.

If I were going with a 6mm bullet, I would eliminate all the recoil too. 6 dasher has proven to be an excellent round

Isn't the dasher a little light for 1000 yards? I'd also like to possibly use this for deer hunting out to 300-400 yards. I'll have to look at the specs for the Dasher again. It's been a while.

Looks like the round is hot enough but brass is hard to come by. You have to get 6mm BR brass (which is expensive) and the fire form it or pay someone to hydro form it, increasing the cost even more...

If brass cost is much of a factor then 6.5 cm will be the way to go. You can get once fired hornady brass cheap

FYI . . . the Ruger American Predator is chambered in 6Creedmoor and has a 1:7.7 twist rate.
Thinking on getting one of these after a little more research. Not much money either. AND . . . with 10 minutes of work,your gettin' another $150.+ worth of trigger.
I have several other Ruger Americans. The "V" block bedding system is great and the accuracy is exceptional. ---- SAWMAN

The cm stuff is a big marketing scheme. The diff is the twist rate on barrels. From what I have heard they basically stole the .22/243 and created the 22 cm. Same thing with the new 8.4 or whatever, they copied the 338 Federal I guess. Thievery imo, and I am not a fan of that. I will pass and go with non-thief products. Just my opinion though.

Yeah. The main reason I am leaning towards it is that there are lots of decent factory rifles that cost much less than a custom build and the 6mm CM has a faster twist rate than the 243 Win and 6mm Rem do in factory rifles.

I just want to make sure I wasn't overlooking with the comparison.

The Creedmoor's have a longer neck also. Some say better to hold the longer VLD bullets that the "new and better" owner is "supposed" to shoot.
Me . . ??? . . I say . . bla,bla,bla. ---- SAWMAN

I'm a 240 weatherby or 6mmbr guy. I use the wby for hunting because it is the velocity King. But when I'm out for accuracy it a br or br offspring that rules the day. If you want to know what's hot in calibers start googling match results. You might be surprised if a lot of top 10's are 6 br, brx, dasher, xc

The 6mm Dasher is a beast. I have always wanted one. Sometime I want to get one. Need to break down and sell a couple of rifles I guess.

The dasher and the brx are both amazing

I’m going to pick .243 for the benefit of shtf. Every single person I shoot with owns a .243.

243 is a great round also. I hope you enjoy it. What twist rate are you going to go with?

The 243Win is a great chambering. Especially nowadays with the great bullets in partition or no lead style.
During my years guiding in Maine,I had sports kill some of the bigger bodied deer,and used it for longer range coyotes.
In the last several years there have been some lower weight bullets offered (55,58,60gr) that will turn the 243 into an excellect varmint gun. Ìf a faster twist gun,it will also shoot the >100gr bullet waaaaaay out there.
IMHO . . . the 243 and the 7-08 are two of the most overlooked chamberings produced.
Great choice sir. ---- SAWMAN

What about 243 AI? Looks like you can shoot 243 Win and 243 AI accurately if properly setup. Everything I read so far has been positive other than the cost of a custom rifle or having to rebarrel a factory rifle.

I have a close friend with several 243AI's,and two 260AI'S. My wife has owned and hunted exclusively with a T/C Contender chambered in 30-30AI for 25 or so years now.
My buddies AI's all shoot <MOA. My wifes T/C will shoot just a little >MOA @200yds. Forming brass is easy. Drop in a 30-30Win . . fire . . out pops a 30-30AI. I started with cheap factory ammo but you can find the cheapest bullets and powder,load them down pretty low,and fire form your own. A plus is that my wifes gun would shoot factory 30-30Win ammo almost as accurately as fire formed,hand loaded AI ammo.
My wifes 30-30AI will shoot the heavier bullets (150-168gr) about 130-150fps faster than if shooting the 30-30Win loads.
For loading info on the AI's you just start at book max for the origional,then work up from there. Almost everything has been AI'ed. Some are good,some are ho-hum. --- SAWMAN

Picked up this new 6mm Creedmoor, Ruger Precision Rifle, for a pretty astounding $749 at a big box outdoor store... Not sure if I'm allowed to state which one. A quick perusal of the various ads will reveal it. Both the 6mm Creedmoor and the 223 variants are avail at that price.

I had a Vortex just sitting around doing nothing, so it found a home, as did a spare bipod.

Looking forward to getting some range time with this Big Ugly Ruger. :)

I've been loading for and hunting with a 6mm Remington since the mid 1970's. This will be a bit of a change. I haven't even got dies for it yet, just a box of factory match ammo, 108 gr Hornady.

So - if someone is looking to get a 6mm Creedmoor... This is a great bargain!

Regards, Guy

$750 is a decent deal.... you can’t build one a whole lot cheaper
