The factory full throws a really good pattern in most M2s. If I remember correctly my count was like 230-240 in the 10” and about the same in the 20”. My IC .555 will throw 300 in the 10”. All these numbers were at 40yds and shooting 2-3/4” shells with 1-5/8oz of 9s. I’ve got 2 buddy’s that shoot the same gun and all they shoot is the factory full. Hope this helps
