mickey,

I think that the action of the gun was made in Belgium. I have seen quite a few like that and some
knowledgeable people have always said to me that these actions were from the Continent.
Re accuracy, that's great. I'll try to get round to posting some of my targets when I can find them.
I have a 450/400 that does the same and my H&H500/450 U/L Hammer used to shoot like that
all of the time.
