Like many others revolver shooters, I would love to shoot ICORE but that isn't available to me locally. Making a space for 8 shot revolvers in USPSA would be the next best thing and would hopefully grow the division. I think there needs to be a subdivision between the 8 and 6 shot revolvers so they are both recognized as revolvers but they don't compete directly against each other. I think it's great to add new shooters but not at the expense of the existing loyal shooters that have earned there spot.
Why not make a personal investment of your time and start an ICORE club? I understand that the Pioneer Gun Club could support an additional discipline. Here is a link to the ICORE club info page.
