Edgar, there is no more PB, 7625, or 4756. I would first go to the powder company web sites to see what works in the 16ga.
http://www.hodgdon.com/ or http://www.hodgdon.com/ are two of the biggest. BPI's SG16 looks like the shortest wad they have and it's what you want for 2 1/2. Here's their web site - call and talk to them. http://www.ballisticproducts.com . You guys with reloading questions - we have a forum for that - it's near the bottom of the forum list.

Yes, Paul. I knew that. I was just posting MY recipe for 16 ga., and I have plenty of both 7625 and PB. In fact I just picked up another 5 pounder of 7625.

lucky guy
i am afraid what i have is all I'll get around- but at least enough for future hunting and a little clays

Rick, there's plenty of powders we can still use - just gonna take a bit to figure out what's best. Unique, Green and Blue Dot all work with lower pressures in the 10ga guns. 12ga over a 1 1/8 could be a problem, but at 1 1/8 or less there's plenty of powders for low pressure.
