I noticed his complaint about the cost of the ammo, .416 Rigby at $106, I just spent £96 on 40 rounds of Federal 7X57 for my .275 Rigby as the RCBS dies arent yet in from the importer! Its scary but I will keep that ammo for my week long stalking trip to Angus this coming November. As back up I will take my CZ550 FS in 6.5 Swede as I have far too much ammo for that!
You should buy something in 7.62X39 perhaps a VZ58 or equivalent.
