That is a fine WR 375H&H there , just looks great !

On the sight , I have seen them to that range on 303's (heaps of them) 577BPE , 450/577Sniders , Bore rilfe's & Cape Guns , I think the 375H&H is equal or has the edge on them all

!

I was told in SA at one time ever house hold or farm had to have a rifle in a military Cal-450/577 early on then 303 , that is why so many Cape Guns in these cals , any way when in a stockade or strong hold , all the defenders could use the long range sight to lob a hale of lead on the attacking masses , or some thing like that ?

Not the answer for your 375H&H how ever .
