Angel don't mix and match your componets. Compression formed hulls such as the Win AA and Rem STS are pretty much the same but the Win HS hull uses a special HS wad. Shotguns arn't as finickey as centerfire cartridges but if you going to load low pressure shells than a change in primers for example can change pressure.
If your going to load 2 1/2 inch 16's for your hammer guns i can pass along some usefull information. Also there is a web site devoted to the 16ga, it's called the 16ga society and they have a lot of good info.
I'm currently loading low pressure 2 1/2 12's,16's & 20's and working on a low pressure 2 3/4 inch 20ga load using Alliant 20/28 powder. If I can be of any help just let me know.
