I’m currently downsizing my gun/ammo inventory. I have a bolt action hunting rifle in each caliber and ammo for each. Isn’t one of the 2 caliber rifles capable or shooting both of the ammos, but the other caliber rifle can only shoot the ammo it’s labeled for. Also is there any advantage/ benefit to one caliber of ammo over the other? Thanks for any input.

However, the reality is that any quality modern bolt action is built to far exceed the pressures developed by 5.56 in a .223 chamber. A .22-250 generates up to 65,000 psi, while burning substantially more powder, generating more bolt thrust due to the increased case diameter, against a weaker bolt due to having more material removed to accept the larger case head.
If you have some off brand stamped sheet metal Brazilian made .223 it might be a problem, otherwise it’s unlikely to be.
