I have a Savage LA set up to use a .260 Remington Lightweight Sin Arm barrel for deer and a .204 Ruger factory sporter barrel for varmints. I use Go and NoGo gages for headspacing consistency. I do not have any problems chambering factory loads and see no measurable change in accuracy. I also reload, so I recheck my chamber length and bullet seating depth after swapping barrels just to make sure I don't have any suprises with the reloads. Both barrels shoot better than 0.5" MOA most days with the right loads which is more than fine for deer, hogs and Pdogs. So with the calibers you listed, I would just swap barrels and shoot'em.
