I lost my sierra loading manual in a basement flood. I remember that David Bradshaw said that the 7br with 150 gr matchkings with a charge of WW748 was a great load. If memory serves me correctly, it was 28.2gr. Can anyone confirm the charge from the manual?

The Sierra 6th edition no longer lists WW748 as a powder to use. I have attached the page for it.
I have had the most consistent results with 28.0 Grs of IMR4895.
