That 475#2 on Champlins table is still on his website! It is a Francotte, and is light, but manegable. Price is $6850

The bullet diameter is indeed different for the two versions of the 475#2! The 475#2 Nitro Express uses a .483 dia,480 gr bullet, and the 475# Jeffery uses a .489 dia, 500 gr bullet. Both were loaded with 80.0 grs cordite!

I just happen to have 80 rnds of brand new HDS brass for 475#2, so this rifle is looking better to me all the time!
