I was recently looking through articles online and saw one talking about the 375 H&H which led to the 375 Ruger which led to the 416 Rigby etc and suddenly buying one seemed like a good idea to me as I've never had one that size. I saw a couple of Ruger No. 1's in 375 and 416 online but I really like the CZ 550 African.
Talk me out of buying one in that large of a caliber. Maybe hard to cast for? Find brass for? Uses too much powder?
