The 1 in 9 twist of the 6MM gives you more options on the good bc bullets, over the 1 in 10 of the .243.
The nearly 100 fps you gain, gives you less wind drift and less drop.
There are a lot of great cartridges that are not that popular, 222 magnum, 220 Swift, 257 Roberts, 260, 280...
Not everyone wants to shoot a .223, .243, 308, or a 30-06, all the time.
That is an interesting point, and I think you are right.
Funny thing is, Winchester makes a special run of 6mm Rem brass cases about one a year, and they are sold out before they are made... the 222 Mag hasn't been a factory cartridge for 50-ish years, yet the brass is in continual production, and custom rifles are chambered in it all the time (and it is a favorite of mine).
Winchester made a run of .257 Roberts rifles last year and they were sold before they even got out of the factory. I tried to get one and they were already gone.
Kinda says something, ya think??
