There are only 4 African calibres - for want of a better term - that I have lusted after. The 375H&H, 416 Rigby, 404J and the 505 Gibbs. I have the first two so don't see myself picking up a 404J and the recoil of the 416R is about my limit so do not, apart from cost, see myself acquiring the latter, though it would be good to have one and those Heym's sure look good.
