22.5 grains of PB, 209A primer, 12C1 wad, and 1 1/8 of 7 1/2's gets you about 1200 fps. This is out of a old IMR book. The online recipes are hard to find. I have dropped down too 21 grains for a nice lite load and up to 23.2 for a handicap. They all shoot great.
Dave has it nailed. I shot that for several years back when I was in my heyday. I shot new Fed Papers and then reloaded the empty once. They were fantastic loads out of a FC Perazzi bbl. Doug Braker did my choke on the TM1, but the bore was factory. Dougs FAve is right at .033. His and my mentor felt that .033 was ideal to producing the right combinations of density and pattern size. So, go wiht the 22.5 gr of PB and you will have a very soft shooting load for hcp.
