I patterned my 11-87 with 3'5" 2.25 7's and got 242 in 10". I draw the 10 before I shoot, got 150 in the top half and 92 in the bottom. I like it this way as I aim at the waddles. Question is, how much higher will the shot be at 10 or 20 yards. I don't think it will be more than an inch or two. I'd like to keep as many of those tiny 7's out of the breast as I can, if you know what I mean!
