My views are mine and mine alone.

The Big Game Rifle is - as others have put it - a Magnum Mauser rifle with a german/american inspired stock. It has NOTHING to do with the fast-handling rigbys of old other than the name on the barrel - which sadly is something that can be bought these days. Which it has.

Dont get me wrong, its probably a fine rifle. But its no Rigby as we once knew it.
As long as you accept that its a modern-day safari rifle with modern-day handling statistics, then by all means - fine.
