They dropped the 260 chambering last year but it was only in the sporter weight rifles not the tactical.I just checked their new catalog I got last week and they are only chambering the 7mm-08 in models 10/11/and 16 which are all sporters.I never remember them ever chambering the 7mm-08 or 260 in tactical.Bet it was a misprint in your gun book,I' ve seen that before.Wouldn' t be any big deal to rebarrel a tactical to 260 or 7mm-08 however,with savage the barrel nut makes that easy.
