Last night I couldn't find the article I referred to above. Turned out it was at the office. Autumn, 1999 DGJ. He said 13 rounds of the old factory ammo averaged 2663 fps over a PACT chronograph. I wonder where Wright got his pressure and velocity figure. I've always seen the .350 No. 2 listed at 2600 or 2625.

I pulled up the "Mystery Rigby" thread. Odd. My reference books cover quite a few obscure British rounds, but I've never seen mention of a .350 Flanged Magnum. Since the No. 2 seems to have actually been loaded to 350 Rimless Magnum velocity, the only reason for a flanged version of the rimless would be reduced pressure. I wonder where Wright got his information on it? Perhaps he found a reference to it somewhere that simply used the incorrect nomenclature for the No. 2?
