Speaking from a reloading perspective, which would most prefer, the .243 Win ot the .244/6mm Remington?
I do not believe that is correct. The original designation was .244 Remington and was introduced with a slower twist barrel. They changed the designation to 6mm and sped up the twist. The 6mm is capable of slightly higher velocities. The neck is also longer than the .243 and holds the bullets better. I vote 6mm!The same, sort of.
The 6MMs are normally chambered with slower twist barrels, thus limiting the use of heavier bullets.
The .243s barrels normally have faster twist and will handle heavier bullets.
With the same, lighter weight, bullets they both have generally the same capabilities.
I have always favored the 6MM but feel the .243 has more versatility.
This one falls in the category of personnel preference in bullets weights for a given use.
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.Don't know about Arkansas, but here in Wyoming, you can get 6MM anywhere you can get .243.
Heard a story once about Jack O'Conner. He had little use for the guy that designed the .243, but had even less for Remington, so he got around it by just promoting Winchester rifles.

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.
