I am lucky enough to have a Mauser M03 (which is a great rifle). I am going to get a second barrel for some upcoming Fallow outings and was wondering if anyone would recommend either the .270 or .308? It seems sensible as I would like something with a bit more punch and I may take it to Scotland next year and I know from experience they prefer something a bit bigger than my .243 'up there'.
Anyone have any experience or recommendations?
Thanks in advance.
