"Doing fine" is perfectly acceptable for a hunting rifle, and your gopher-capable groups will serve you well beyond what a precison shooter would consider burned-out. This is a precision rifle forum and most precision shooters have a considerably higher standard of accuracy. When a barrel stops creating .2-.3 MOA 15 shot groups, it ceases to be useful to me.
Simple bullet weight differences have little to do with barrel wear. That is a byproduct of heat and pressure. Depending on the powder, you can have maximum loads over 60,000 psi, or you may have maximum loads with pressures barely 45,000 PSI... all with the same bullets. How you shoot your firearms determines barrel wear. Heat is a throat killer.
While there are certainly contributors to forums, whose credentials may be questionable, there are many whose credentials are above reproach. Look before you slag.
204 Ruger or 223 in a tikka would be my choice. Both of those mentioned are barrel burners, especiallly with the amount of shooting one can do in a session. You "will" heat the barrel up way quicker with the 243 and 22-250. I know, I have been there and done that. It is also nice to spot your hits, if I were to use them again I would put a brake on them. May I say I don't want to start a brake, no brake, too loud, blah,blah,blah.
