Which do you shoot best and sing to you?

The 275 Rigby and 375 H&H are the obvious ones to keep as they are probably the ones that work best in the field on paper. But it comes down to individual preference - which fit the best and shoot best for you - those are the ones to keep.

The ones that look pretty, but you never use - they are the ones to pass on.

My view is that Rifles and Shotguns should be used and not safe queens. Using means careful use and not abusing. A rifle or shotgun is a precision instrument not a walking or climbing stick.
