We get 'em here in Oz, popular in the .416 Rigby chambering. The two I have had a bit to do with, belonging to two close friends, were both quite acceptable quality for the price. Neither has ever jammed to my knowledge, both have fired over 500 rounds without a doubt.

They were imported a couple of years ago though, has the quality slipped since then? ...or is this problem peculiar to the .458?!
