A bit of research found that this is for 1-1/4 oz. lead shot loads

This statement is what threw me off, as I had thought you had made enough research to see that there is a multitude of hull/wad/powder/primer combos out there. I'm sorry that I was not more specific, but without knowing what hull and wad you are using then it would have been a total guess and not even a good one at that.
Get yourself one of the books listed by Howard, the RCBS shot shell handbook and the Lyman shotshell manual, I would get both. There are loads listed in one that is not in the other.
Shotshell reloading is one case where trying "stuff" just to be trying it, will get you in hot water fast! Shotguns are much weaker by design than some of the other guns, so play it safe and ONLY use listed load combos.
I have found that is best to find a load that works as you want and stick with that load, swapping back and to between powders/wads/primers only leads to confusion. I am not saying not to experiment to find what you want, but only that when you find THAT load, stick to it. I tend to pick one hull, it used to be the Winchester AA, but I find myself leaning toward the Remington hull lately. I do the same with wads and powder too, volume buying is the way to save $$ with shotshell reloading. Bushings are reasonable too, so there is not a lot of $$ tied up unless you have to have one of every size, the adjustable bars are OK especially for finding "that" load, but again I tend to stick with bushings.
Welcome to the world of shotshell reloding!!
