I have two 32 ga guns one double and 1 single shot both damascus guns. I load 5/8 oz of shot by volume with AAA goex in the 2 1/2 plastic hulls and I also have some magtech 2 1/2 inch brass hulls that use the small pistol primer. I see midway still sells the 32 ga 2 1/2 brass hulls. They would be a good alternative if you do not have a crimper. I use a GAEP crimper. I think Ballistics products has the 32 ga crimpers now.
