I currently shoot a blaser 6.5x55, mainly fallow. This does everything I want in the uk. I also have a 308 barrel, this just mainly gets used for boar now. My question is, when my certificate comes for renewal Is it worth changing the 308 for .30-06, purely as a driven boar set up. Just a bit more performance with heavier bullets? Or should I just leave as is. Is there enough difference to warrant the change?
