Caliber wise if you do intend to use this on goats and yotes I would say that the .223 is a tad light(for goats) and the .308 a tad heavy(for yotes). A .243 or 25-06 sounds like just the ticket. Rifle wise you should just go fondle them all and make your decision on feel. All of the rifles you mentioned will shoot just fine if you do your part. I'm sure that some will say the .223 is fine for goats but I'm just expressing my personal opinion that a little larger caliber would be better.
