.30-.357 breech seated load data?

I've got a .30-.357 chambered Ruger #1; 1in 10 twist. I used a .300 BO reamer run in enough to use sized down .357 mag brass. I'm breech seating an Accurate 31-175 PB. I've been using AA#9 but am not getting a good burn. With Fed Magnum Small Pistol it works okay but changing to a standard small pistol primer leaves it looking like I'm using black powder and starts to lead immediately. So, right on the edge I'm thinking. Was thinking of trying AA#7, Blue Dot or HS-6. Wondering if anyone has been down this road before and has some good load data or any other pertinent advice?

Thanks in advance.

P.S. What's a good name for this cartridge? .30-.357 Blackout maybe?
