Oskar-thanks for the info. The High Pheasant loads I have a friend brought me about 10 years ago. They are 30 gram~1-1/16 ounce of shot. The B&P site used to show pressures for their shotshells, but I can't get the current site to function.

On a Gamebore site I find that Pure Gold shells have a 1400 fps velocity. They can't be low pressure.

RST doesn't list velocity for their loads either. I guess I could call them. They have been helpful in the past.
