Yes, it costs the same as a 5.56/223
If you are building one yourself the only difference is the barrel, and you can pick them up for $200 on Midway
If you are a handloader then the cost of ammo is pretty similar also. Maybe the 308 projies are a bit more expensive but you load in 20% less powder along with the dies and that's about it.
If you have a 223 upper and a few tools you can buy a 300 barrel and swap out for a taste-test. Try the new calibre and if not satisfied swap back. For the cost of a barrel, $200
