Gerald:
I shoot the .375 Flanged(2 1/2") a good bit thru an English double regulated for 270 grains and I have found the Woodleigh bullet to work best. From memory I think the velocity to be around 1900 ft/s and just a guess that the max pressure is somewhere near 38K psi. I also think to recall Elmer Keith shot a 0.375 Flanged in an oval bore and gave something close to 2100 ft/s but I bet the pressure was a might bit high. A "F" on an Austro-Hungarian would mean Foreign but this is a Pieper. I'd like to see a pic of the marks if possible.
Kind Regards,
Raimey
