yes i will be hand loading for this project!! can’t wait lol
A 6mm has limitations regardless of what case it's fired out of. I don't think I ever thought "hey, I can stretch it out another 100 yards with slightly heavier bullets". If I need more range I just grab something bigger out of the cabinet that has higher down range energy, makes bigger holes, and higher BC then the marginal 6mm 115's. I'm not so recoil shy to be stuck trying to make a 6mm do everything lol.
I also prefer premium hunting bullets (bonded/partitions) with lower BC then anything Berger, they are good target bullets, fine for blowing up ground hogs and the like that I'm just ridding the land of, but not nearly solidly constructed enough, or properly expanding enough, or reliable enough for me to shoot at things I plan to eat. Poor choice in a hunting bullet regardless of how much they market it.
At 500 yards my 105 Berger has almost 2x the energy of a 95 grain SST. I’m sure it’s over your head and your just arguing to suit your ego. I guess you could build a custom .243 and run the heavier billets....but then you run out of magazine room and end up seating the longer bummer back in the case, eating up the extra capacity.
I’m sure you will come back with some other reason you don’t want a 6....and that’s great for you. The OP asked about a 6 creed...
243Win with 1/9 twist will shoot many of the 105's and 107's just fine with factory twist, so when you compare apples to apples, which you don't seem to want to do, with 105's the 243Win will still have a velocity edge over the 6mm CM, so year, that chart really is a joke, and literally the first article that comes up when you google 6mm CM vs 243 lol
Congrats on your google skills.
Have you loaded 105s in a .243? Did they fit in your magazine? If they did, do you know how much powder capacity you took up with the long bullet seated deep? How well did it shoot seated so far off the lands? What was your BC degradation due to the slower twist?
I get it, you could build a custom .243 that would mostly get you what you get out of a 6mm....that’s not really the point....

Because the entire point of the argument is that you CAN use different bullets. That’s the advantage. Literally the point of the cartridges development.
Anyway. I think I’ve represented my opinion on this topic. I don’t feel the need to further convince anyone. Math is hard for some I guess. The 243 Win is a fine deer round, no problems at all. It’s just not as good the 6mm Creedmoor. Inferior in every way but price and availability if you’re not a hand loader.
Guess again ..... Any time there are comparisons made there needs to be similar test materials used for real results. Otherwise you're just making up numbers, going back to the math you mentioned.
Why not shoot heavy RN bullets from a short bbl 243 and compare it to a 24" 6CM with sleek high BC bullets at long range and tell me how great the 6CM is?
The graph does have some issues- among other things, I don't believe Barnes makes a 127 6mm?
But the point that many factory 243s won't shoot the same heavy bullets well that most factory 6CMs can, is valid. We've tried the 105-108s in a few 1-9 243s, with varying degrees of success and knowing we weren't maximizing BC. That's setting aside the fact that many factory 243s are 1-10 RoT. And... Setting aside the 112-115 6mm bullets completely...
You’re just arguing for the sake of arguing. Congrats on your post count!
“If you take a cartirdge and custom load it in a custom gun you can make it sort of match a different cartridge...”
The fact is that a Factory .243 does not keep up with a factory 6 Creed past 300 yards.
They don’t tend to shoot as well, and aside from ammo availability they offer no upside.
You can make up arguments that you could build a custom .243 and single feed hand loads and get there...but why?
You are 100% correct. Here the published article the chart was taken from. Its simply comparing common factory ammunition. The author obviously captured a 6.5 Creedmoor factory load in his data set.
