BPI has plenty of data for 3/4 and 7/8oz loads in 2 1/2", 2 5/8" roll crimped and 2 3/4" fold crimped 16ga. Sadly a lot of it is with discontinued powders, but there is enough with common powders, 800x, Longshot, Universal Clays and International Clays. Luckily I'm getting old so my stock of PB should last me until more data is available or I'm too old to hunt.

Most 2 3/4" fold crimp data will fit in a 2 1/2" roll crimped shell. I just make sure my 2 3/4 data in 2 1/2 cases are at the lower end of pressure.

2 1/2" 16ga left/red - 2 3/4" 16ga fold crimp right/black

After the first shot the rest are just noise.
