Thank you for correcting me, you are right, the headstamp is "GP-B", I'll insert the lateral image later, here is a passage from TonyE's site:
"Cartridge Gallery Practice .303 inch Mark II (Smokeless) Canadian Pattern" was approved about 1908 for service in Canada.
It utilised a ball case loaded with a heavier 125 grain lead bullet with one external cannelure. Both British and Canadian made cases were used and early examples had headstamps from Ball cases of the period, sometimes cancelled by ring stamp. Later cases were specially made and were headstamped "GP-B", indicating "Gallery Practice - Ball".
The propellant was about 5 1/2 grains of smokeless powder and there was no neck cannelure in the case.
Velocity is not known.
