My 1st few years I was a non-beleiver in patterning a gun. I just went out and hunted. Then I missed a bird a couple years ago, and I was crushed. I patterned my gun and was only getting around 70 pellets in 10 at 40.
I am now a beleiver in more is better, so now I stick with the 100 minimum. But more is better, I wish I could get all of them in 10" at 40
