I don't mean to take exception with your comment, but I don't think that is gonna work. I'm not expert, but a .223 action is based upon a 5.56 caliber casing and a .243 actions is based upon a necked down 30 caliber .308 casing. So you need not only change the barrel, but you need a .30 caliber action as well if you want to go .243 caliber. Might want to check with a Gunsmith because that could cost you much more money than just the price of a barrel.

we're not talking .223 vs .243. it's .223WSSM vs. .243WSSM. completely different.

The fact is that the .223 WSSM and .243 WSSM calibers are based on the same size of cartridge, with the only difference being the caliber diff. IE: In theory you could take the .243 WSSM Brass and "Re-size" it to .223 WSSM size just by running it through your .223 Full Length Re-sizing dies. Again, in theory but not practical since the WSSM brass is so much thicker, etc..
With the .243 Win and .223 Rem, they are totally different base cartridges in size, shape, etc..

"magnum" is a meaningless word for the most part. Change it to ".223 flufferdoodle to .243 flufferdoodle" and you have the same thing. Lots of calibers are more or less the same brass wise/bolt face, and only require a new barrel installed properly to change, maybe a little brass trimming for length. 30-06/.270/25-06 etc. Those 'super short mags' fall in that category.
