Yes and no. Who "really" needs a season to do a barrel swap? If you want to change calibers, just do it!! There's a BUNCH of folks that have a supply of different barrels. It just takes the urge or desire. One rifle, different calibers. See an interesting caliber you think you might like to try? Pick up a pre chambered barrel and bolt head if needed and go for it.
I go from 17 VHA to 20 VT to 20 VT "short" Wildcat to 20 TCM Wildcat to .221 Fireball to .223 to 22 BR to 6 BR to 6.8 SPC to 6.8 BR Wildcat and a few in between.
