hi all , I am just thinking out aloud . apologies if this question has been asked before and I am repeating it. I am of the opinion that the Winchester M70 is one the finest value for money rifles available as a factory produced rifle. what then is the difference between the 416 Rigby and 416 Remington bullet and ballistics in your opinions as Winchester do make the M70 in 416 Remington . thanks in advance .
