With the opener 3 weeks to the day away I finally got everything dialed in. I patterned both guns over the course of the last several weeks and dialed them in yesterday.
After a few other shots this is what the 870 did: PG 670 and 3" mag blends {202 in the 10" (my tristar looks the same, only with a little more hits in the 10")}
I like to put the dot on the birds head, so when I raise up a couple of inches he is going to get a good bit of shot in the head. Im guessing the only thing he is going to do is drop!
