Picked one of these rare No1s in .243,lovely gun, I also have the Stutzen International in 7x57, a tack driver! As these calibres are no longer made for the No1 it just adds to the feelgood factor,single shot rifles definitely focus your mind..also the rifles shoot PRVI sub 1/2"! My two were made in 2001 and 1995 respectively. Maybe a 7mm Rem Mag next ?
