Don't know about Arkansas, but here in Wyoming, you can get 6MM anywhere you can get .243.
To the world, you may be only one person. but to one person you may be the world.

I prefer the .243 in my Sako A11 heavy barrel. With my loads, it shoots one hole groups at 100 yards when I do my part. It is also very easy to load for anything from small varmints to deer size game.

Got a real nice old 700V in 6mm......and a lovely 700 in .243.

The former has been a very solid varmint rig,still wearing its original 6-18 Burris.It shows a marked preference for Sierra 100 g'ers,be that match or gamekings.Loads and shoots very easy with IMR 4350.Case life is alittle better than the .243's.

Our 700,.243 loves the Sierra 85 g BTHP's to the degree that you can call it a one load gun.Its now wearing one of our stocks and a period correct('69),Weaver 3-9.Although it performs on paper and varmints with the 85' has been an amazing performer with Speer 100's(plain base) on small to med. Deer.The case life isn't quite good as the 6.

If I was building from scratch would go with the 6mm.

Edit to add......just refilled my coffee,theres 4 Deer standiing in the yard behind house.They're does........IF,it were hunting season,the .243 would've been the go-to rifle to drop one of them.Thats how we've always seen the .243.......handy,efficient,get the job done calibre.The 6 always seemed to be a little more purpose driven.

I would love to get up to Wyoming more, only been there once or twice. Lots of game to hunt and open spaces, I can see the need for the flat shooting rounds. I have hunted from TX for hogs to SD for pheasant and pdogs. We usually stop at WM or a small shop for supplies forgotten and I always check to see what ammo they keep on shelf, most places seem very basic calibers 223, 243, 30-30, 30-06, 270, 7mm-08, and 7 mag. It is hard to find 16 ga shells anymore for my dads Browning.

On a side note, .243 can be made from .308 brass and 6mm can be made from 7mm Mauser or .257 Roberts cases.
In life, strive to take the high road....It offers a better field of fire.

I throw this pic around on here a lot, but it's just so damn good! This was with my wife's Tikka .243 and a nice load I worked up. 95 gr SST, 44 grains IMR 7828, CCI BR-2 primer and Hornady brass.

That is interesting. In one of the older Speer reloading manuals, Jack O'Conner talks about once having had a custom .244 built on a Mexican Mauser action by one of the leading custom gunsmiths of the time. He states how he could not get it to group well at all with factory loads. He then loaded up some 90 grain Speer bullets and the gun shot sub MOA groups. Either Speer paid him a lot of money to say that or he really did not mind the .244 caliber.

For the reloader, the 6mm is preferred. For the guy using store-bought, the .243 reigns.
