This is Mike, Ned's Friend ( YES He has some friends), I went ahead and registered for myself
What I have been loading for 10 gauge 2 7/8 are OLD Remington Hulls cut to length, Remington *57 primers, 25 grains of Green Dot, Remington SP10 wad, two cheerios, 1 1/8 ounce of shot and a six star crimp.
You can also use one cheerio and use 1 1/4 ounce of shot.
And you can go up to 28 grains of Green Dot, and 1 1/4 ounce of shot, but when I shoot skeet with my NID the recoil is pretty high.
The Ithaca NID has 32 inch full and full barrels and swings quite nicely
Enjoy the day
