I have a number of Pope barrels on '03 Springfields that were for jacketed bullets and they are all right hand twist while his single shot lead bullet rifles are left hand twist. They all have Pope's markings on the bottom of the barrel, an example is:
650
WL
HT
14/0
3/5/24
H M Pope
My take on the caliber marking is the barrel was originally something like 30-06 and when it was rechambered, they added this caliber marking. None of my jacketed bullet Pope barrels have a caliber marking on them.
