I would load Unique if you can find some. 1 1/8 ounce fits in a 67MM hull but is tight, I load 1 1/16 ounce, with very good results. By reducing from 1 1/8 ounce to 1 1/16 ounce I am sure the pressures are reduced. Powder does burn well. By how much I wont know until my test results come back form Precision. This data is directly form the Alliant website. I picked the Windjammer and Fig 8 loads as I had tons of those wads on hand and the 6,400-7,000 psi was well within my target pressures. I also loaded some 1 ounce loads but am awaiting their tests as well. That might be my best load as long as the velocity does not vary too much.
