Kirby's got a cute William Evans double in this calibre. I must admit I've never heard of this calibre before. The 400/350(Rigby?), yes. The 400/360? no.

Can anyone expand my horizons just a bit?

I appreciate it. - Marc

Both Westley Richards and Purdy made a round by this name. (They are't interchangeable) Basicly 1950 with a 300 grn pill. IIRC many of these were rechambered to 9.3X74 (more power too)when it became hard to find ammo.

Thanks very much, Mike! - Marc

You're welcome!
