I patterned the lead version of the shell, Iam not into paying 3.00 a shell for the heavy stuff. I used the 3.5" #5's I think it was 2.25 oz. payload; these things patterned great in my MP153 consistently getting 25-30 pellets in the kill zone at 40 yards. 40 yards is my self imposed limit due to my eyesight.

I also patterned the heavi shot 3.5" #5's (not sure of the payload), but the Federal ammo out performed the Remington hands down. I found my new shotshell and saved $10.00 a box.
