Hi All first post here. Scouring the net and my manuals for data for the right Cowboy load for my 51 Navy Pieta 36 cal with 38 conversion cyl.. I am using hollow base wad cutters in .360 in a 38 spl, brass the Bullet weight is 128gr from a mold by MP molds. I want to use as light a load as I can to start, and am looking to be able to use Pyrodex, or Smokless (Unique) . Looking for 700 fps as a starting point. So far I believe 15grains Pyrodex (110% compression) or 3 grains Unique is in the ball park.
So I have questions:
1- Since it is hollow base I do not think a over powder card is appropriate?
2- What will the differences be in pressure between the Pyrodex and Smokless at the same velocity?
3- Where can I find data on Pyrodex loads that list chamber pressure?
4- What says you on my load weights? 15 & 3
Thanks for any help!
