    I got one of each - if you are building one, it doesn’t matter. If you are buying a factory stick and want to shoot the heavies the creed wins hands down. I also have to second the hornady match stuff in the creed. Those 108’s make you question all the expensive reloading equipment you own and the time you spend at the bench.

    My creed is the nicer of the two and is also a newer toy, so I would give the creed the nod right now. Mine is the bergara premier approach and I love it.

    I had a 6mm that was like a 243,,, not sure who made them back then,,, fun to shoot predators with...

    I can't vote for either since I'm building a middle ground rifle in 6.5/06,,, the 0.250 thou on each side of the 6.5 will be very close...

    Purhaps my next build will be a 6.5/7mm Remington or a 6.5/300 Winny

    Of course I won't know until I get there. Ha

    If the major rifle manufacturers offered the 243 Win. in a 1 in 8" twist or even better, a 1 in 7" twist, the 6mm Creedmoor might not have even been developed. I have multiple 243 Wins, one with a 1 in 10" twist and two with 1 in 9" twist. All three shoot exceptional well but, none of them shoot any bullets heavier than 100gr worth a flip.

    I HAD a Ruger American Predator in 6mm Creedmoor that shoots factory Hornady 108gr ELD Match like it's going out of style! 200 yard, 5 round groups, well under an inch are the norm. My wife tried it out at the range a few months ago. She put a whole box of twenty in the 1" bullseye at 100 yards. Take a wild guess what she's hunting with this coming season! Now I just have to go buy one for myself! :eek:

    That's the kicker, and what made my decision for me. No factory rifles in 243 with enough twist to run much over 100 grains.

    I've only really tried the 6mm Creed and it's fun! I'm sure the .243 could do the same but you would have to reload for it to use the heavier bullets.

    243 if your just going to hunt white tails. The 6mm cm shines at distance as well as on game.
    I’ve killed my share of deer with a 243.
    I have an odd allegiance to the 243 due to my location. Most shots are under 200 yards and our deer aren’t exactly big.
    That being said, buy whichever you like and post pics often!

    If you are building one.....Potayto, potahto.
    Factory rifle? 6CM unless you can find a 1:7.5" .243 Win.

    Depends on what the end user wants to do with it:

    Its really the same argument as 260 vs 6.5 Creed, but for whatever reason people dont get nearly as upset about this one as they do with the 6.5s. Who'd've thought right?

    Like it's bigger brother, the 6mm Creed was designed from the beginning to optimize use of long, heavy, high BC 6mm projectiles. The 243 was a necked down 308 designed around the state of the art (at the time) 100gr flat base soft point /sarc. The rifles commonly available off the shelf for both reflect this key difference.

    If you are building a custom rifle it doesn't really matter, and both will shoot near as makes no difference the same as the other (provided twist rate on the 243 is correct for the bullet weights being run). If you are buying off the shelf you are probably going to have an easier time finding a rifle set up for long range shooting with the correct twist rate etc in the 6mm Creed.

    However, if you are buying or building a brand new rifle and you have no prior investment in either cartridge, go 6mm Creed, its the new hotness which means more manufacturers are going to be spending time and $$ developing around it and the consumer directly reaps those rewards.

    IDK... flip a coin?

    Many years ago, the question would be .243 Winchester vs .244 Remington. I handload for both of those. The longer neck of the .244/6mm Remington was easy to partially size with my Wilson arbor bushing die. The cartridges centered in the rifle chamber with the partial neck size. Longer necks get consistent neck tension and cooler throat temperatures. It is well studied that the .244/6mm Remington barrels had longer life than the .243 Winchester.

    Hornady launched the 6.5 Creedmore when the .260 Remington was already well established. Why? The neck is the difference. 6mm 30-40 Krag.JPG

    I have a Rem 788 .243 Win and a Rem 700 6mm Rem.

    Recently, I grabbed a Seekins Havak Pro 6mm CM. I LOVE THE 6MM CM!!!! And I love the others. They are all ballistically similar on big game. As previously stated, the twist rate on the CM adds some excitement to the game. Anyway, the quality of the firearm is a serious factor. The 6MM CM Seekins is really a great shooter because it's a very well made rifle. So far I'm easily under MOA at 600 yards. I'm going to push it out much farther in July and August. (I'll report after my LR days are over.)

    When I buy a firearm I'm interested mostly in how it will perform for my intended purposes. I grabbed the 6MM CM because I wanted a smaller caliber with excellent LR performance that will also perform well on deer/antelope. 6MM CM is without a doubt a performer in both categories.

    BTW . . . the Seekins 6MM CM is my profile pic.

    The poor 6 rem a victim of improper twist.

    Same basically. I would give the nod to the creed. It's a shorter case so bullets fit mag better. Better shoulder angle. More brass options. Better twist in factory rifles for heavies. I have built plenty of both. But now no one ask for a 243. Creed creed creed. I personally hunt with a 243. But I compete in 1000yard br with the creeds. I like the 6.5 Better for distance because of the higher bc. Shep

    For those of us who love to shoot but do so on.a limited budget, custom rifles are a fantasy yet to be realized. But we can spring for a decent factory rifle. And with a minimal additional investment, my factory 243 became a 243 AI and the hand loads exceed the 6. So I chose to not lament what i don’t have and enjoy what i do have. Oh; and don’t let go of the fantasy. It may be realized one of these days.
