Despite it's disadvantages as a rebated rim cartridge, the 425 Westley Richards was standard Game Department issue in Uganda for a long time and they apparently did not have too many problems with it until the ammunition became scarce.

It may not have the romance of a 416 Rigby or other equally great cartridges but it was good enough for the Game Department of a prominent African country in the golden days of African hunting - enjoy yourself building one and do post pictures of your rifle when it is completed.

Good hunting!
