Sound advice from a few guys on the 450 Rigby. I shoot one, and I would not trade it even for a 500 Jeffreys or 505 Gibbs. (MAYBE for a double in 500 NE....) Have a look at an article I wrote on the 450 on my website, www.huntingsafaris.net
In it I also explained how easy you can fireform 416 Rigby cases to 450 Rigby. I do not like Bertram brass (properly headstamped), and only use Norma brass (416 stamped) that I have restamped. I cross borders regularly with it, without any problems.
