I am debating buying the above mentioned gun made in 1917. It is in excellent condition with 30 inch unpitted barrels that ring like chimes. This is a heavy gun. Can anyone suggest maximum pressure for a #3 frame Parker that is deemed excellent by a competent gunsmith. Would you think factory trap loads or 3 1/4 x 1 1/4 field loads would be safe in such a heavy large frame gun even though the barrels are twist. Surely there were heavy loads in 1917.
Thanks for any observations.
