Nope. Nice try but not even vaguely close mate.
Both examples I gave above are using the same muzzle velocity (3,000 ft./sec). Which is a realistic muzzle velocity for both cartridges using those common and popular bullets, not the hottest load and by no means the slowest. It’s the most sensible way of demonstrating the difference between the two cartridges at the range our mate here told us he wants to be able to shoot large deer.
And why when shooting large red deer in particular, I have come to the view that one is more suitable than the other.
I get the .243 fanboy reticence to see the issue for what it is. Remember I have been a .243 shooter since I was in my early teens, 40 years ago. I can out-fanboy the best when it comes to loving the .243 Winchester. In that time there’s only been a handful of years that I have not been in possession of one. I know the cartridge inside out and back to front, just like you.
I also know what 30% more thump looks like at the business end….
But if you have to identical rifles chambered in .243 & 6mm cm with 8 twist barrels the same length pushing the same pill there’s going to be a difference in thump??
Been pondering something similar but .243 v 7mm08. Since I can't afford either at the moment I'll keep pondering.
I know what I think. I also think that @257weatherby may have been implying the same thing??
It’s totally irrelevant though, isn’t it.
This circular argument keeps coming up. Oh but what if the .243 Winchester has a 8” twist barrel.
It doesn’t. No mainstream manufacturer has ever made a .243 Winchester with an 8” twist barrel.
That would be the end of the story where it not for the fact that a tiny tiny handful of people select a fast twist .243 Win aftermarket barrel. Which if I was the OP is what I would’ve done. But he didn’t. He went with the 1:10”.
So he is stuck with the comparison between the two, in this instance a 10” twist versus a 7½” twist. A lifetime of wondering what if?!
So it is the end of the story after all. It’s not about the brass receptacle that holds the powder. It’s about what length / weight bullet the barrel will shoot. The rest is just waffle.
Can you even buy a factory 6mm Creedmoor in NZ currently? A quick internet search turned up only one retail option, costing $3900.

A couple years ago, I probably would have went with the CM.
Nowadays id probably go with the .243.
I just think availability is worth something. I think at distances where there is a real difference, on game, you should probably be using a bigger gun anyway.

Yup. Very un-fucking mainstream!
And probably north of $4000 by the time the usurious Kiwi middlemen have gotten involved.
So completely unhelpful!
Nice rifle though.

Lol this should stir it up:XD::thumbsup:
Imo.
If your not using the long heavy projectiles then 243.
If using long and heavy then go 6CM.
As in a short action the projectile will end up taking case capacity. Hence, why my old tikka 7mm08 was based on a long action bolt stop and magazine with the 162gr pills.
Since rebarreled to 7mm Creed and it spanks the 7mm08, 160tmk doing 2880fps with only 41.3gr 2208.
If you can find a first gen ruger RPR they were a 1in7.5 or 7.75 twist.
Howa do sell 6creed barreled actions, so they are available as a decent price with your stock/ chassis of your choice
Yeah something like that would be amazing, but as you say incredibly expensive and hard to come by.
If after a while I feel like I'm not getting enough out of the 243 I'll start looking for something twistier or different again. Maybe I'll grow a man bun between now and then, who knows?
So is the goal of the exercise of swapping from 7mm08 to 243 just to reduce recoil? You handload dont you? You could have just used a 120gr in the 7mm08 and used lighter powder charges, to reduce the recoil to a similar level to the 243.
For example, ive just finalised a lighter load for my 8 year old boy to shoot my bitsa Model 7 6.5CM. I used 123 gr eldm's (left over from when i briefly owned a 6.5 Grendel) Ive downloaded them to Grendel speeds essentially. 30gr of powder pushing them at 2570 fps. It has seriously mild recoil, prints a 3 shot group at 100 measuring .35 inch and should hold more energy to 300 yards than your average 243 win load, and once he grows and can tollerate more recoil i can increase the loads.
Adults can still have fun despite what we’re told. I understand the need to tinker and change up I have my main stays and I have gap fillers the gap fillers for me make load development fun no pressure how good can you get it etc etc all of the gap fillers would do just fine as main stays gap filler=scratching an itch to me and having fun in the mean time . I love loading for a new cartridge I hate loading my usual
I think it’s fun just tinkering about and seeing what different calibres can do it would be a boring old world if we all had T3 7mm08’s we’d have nothing to argue about.
Pretty impressed with the 243 performance have been playing around with mine last few days and pushing a 85gr mono at 3290 from a 18.5” barrel, basically zero recoil with suppresor on it and the numbers look very impressive for a wee bullet out to a very long distance.
A fast twist 6CM with high BC bullet outperforms a slow twist 243 with a lower BC bullet, no question, especially when the range stretches out.
But I doubt that a big red hind hit in the hilar zone would notice the difference in the scenario above. She would be dead right there, either way
And when the range stretches out with the lower BC, speed shedding bullet, your chances of missing the hilar zone increase, especially in those pesky fickle gully winds blowing around the faces.
I’ve done heaps of drop tests at 200, 250, 300m with the .243 Win, to nail down my drops as well as I can. Various traditional hunting bullets, 85-100gr. Once I’ve got the ES down to acceptable levels and the drop from the point of aim is reasonably consistent, it’s the horizontal dispersion that raises big questions. Like… crikey… that was off to the left /right, enough to put the bullet slightly too far back on the deer, no problem. Picking those annoying downrange breezes you can’t really see is so hard, especially in our CNI winter conditions.
The >100gr 6mm bullets that have come along in the last few years shoot tighter at that range. They just handle the conditions that bit better, and for me have improved confidence no end at the ranges at which I wouldn’t take the shot with my .243… you’ve probably seen this before but seeing as how we’ve here… Gotta make some new vids.

I see where you're going, and I do have a load developed with 120 VMAX for this rifle and most of a box of them on the shelf. But I've wanted a 243 for about a year and finally decided I would have a go at getting one.
You're right, I could just have one rifle that does it all, (my rem mag gets plenty of love and I take it on expensive trips) but where's the fun in that? A 308 would do it all, but I sold mine so I could buy a shotgun and shoot ducks. Maybe I'll end up selling this as a 7 mill o latte and get a 308 again, keep the 243 barrel, who knows.
Reloading is my hobby, I find it all fascinating, my wife and most of my friends not so much ha ha
I want to learn about a caliber I have no experience with and with a bit of luck and some good shot placement, even put some meat in the freezer in the process.
Plus the barrel swap on its own should occupy my mind for a while at least :D
Then again, maybe a meth habit would be cheaper :XD:
Greetings Rated M for Magnum,
I think your post above says it all. The rifles and the handloading is a journey for you as well as me. Destinations, once achieved, morph into new ones so the journey, fortunately, has no end. Enjoy it.
Regards Grandpamac.
Would you consider 6mm Remington? About 100 - 200 fps faster than 243 and more foot pounds of energy. Then you have two of the American family Remington.
This is not correct, if it is a factory 6mm Remington, its a 1-9 twist or there about, the 6mm Remington was first called a .244 Remington and was 1-12 twist and wont stabilize over about 90gr bullets, after a thrashing in sales, by the winchester.243, the .244 was renamed the 6mm Remington and had a 1-9 twist, by then the .243 win, was firmly entrenched in the 6mm bore as favorite,
I'd prefer 243 due to ready availability of brass.
