To answer you question.
I just stopped shooting trap on a regular basis and I found it cheaper to buy the 100 round pack at Wally world than to buy shot and reload. It was the shot that was expensive, the powder and primers were not outragous.
If the hulls are kept clean and dry I don't see why not.
As for the wads.... Just make sure you have a recipe for those wads.
you may know that there are certain combos you do and do not do.
If you are going to set up the reloader. i would suggest you go buy a reloading manual for shot shells first. They are around $25.
You will need to head for the Win hull section and then look up what load (1oz, 1 1/8oz) and what primer you are going to use.
Personally I pick win 209 as they fit in the hull. I once had some other brand that kept falling out of the fed hulls I was using in a 20 ga when I was a kid. Dad and I were hunting and he noticed that I was loading the shell and then reaching in my pocket for something else and sticking it in the hull and then closing my SBS. It was the primer and when I explained what I was doing and showed him the back of the shells open.... Well no more bargin primers.
As far as powder goes...I like Green and Blue dot for my loads. the Green will give me everything I need for target out of my 20, 12, and 10, and the blue works well for the hot hunting and pot shooting loads, they also double as my pistol powders.
With the shot size. It will not matter the load for 9, 8, or 7.5. Only the speed will matter for the small shot. 1200 FPS is good. All three will break birds from the 27 yard line even with 1 OZ.
Hope this was helpful.
