I'd like to use up my remaining quantity of Winchester 473AA powder and Remington SP16 wads for 16 ga 2 3\4" field loads. Any ideas where I can get load data for this discontinued powder?

My 20 year old winchester reloading guide has gone missing.

There are some loads listed as follows using Winchester compression formed cases and Remington R16 wads (there are no loads listed with 473AA and SP16 wads)
1 20.5gns 473AA Rem R16 wad 1oz of shot Win 209 primer 1165fps at 8300lup
2 20gn 473AA Rem R16 wad 1oz of shot CCI 209 primer 1165fps at 8700lup
3 21.5gns of 473AA Rem R16 1oz of shot Win 209 primer 1220fps at 8800lup
4 21gns 473AA Rem R16 1oz of shot CCI 209 primer 1220fps at 9000lup
these are the only loads in the Win tenth edition
hope it helps
