Home Forums Hunting & Shooting Express Rifles and Big Bores Only Is 375 where big bore starts?

I think that meets the criteria for all, except maybe those that think it's 0.45 and over.


From the other more recent posts it sounds like there is a cross over of meaning between "big bore" and "dangerous game cartridge" where the former is commonly being applied to the latter, which comes back to being a combined calibre/energy definition.

If we talk about a dangerous game cartridge I think it is widely accepted that it is 375H&H and above, although the trusty old 7x57 can take out an elephant if you are careful with your shot, but I personally wouldn't try it outside of an armoured vehicle.
