I brought the 320 accidentally at an auction..... Was meant to bid on the next lot of black powder, but fucked up! was a good deal though.

All good if ya want to sell it, hit me up

I used to load 5.2 grn behind a 200 grn bullet to reach 860fps in my pistol.

You can increase or decrease pressure/velocity a lot in a pistol cartridge just by seating.
Longer slower, shorter faster for the same powder load.

Barrel length of your rifle will speed that up a bit but should still be subsonic.
I think book max for 320 and 230grn is 5.4
