I so agree....
I've screwed up more than once letting the bird get too close , i had to change my set up...I could nail a bird at 60 yds. but I like to get them as close as possible, shame on me, lol...the gun/choke/load combo I was using was great but not for those close shots...I recently got a Mossberg 835 12 gauge so I spent yesterday trying 9 different loads at 40 yds., then I took the top 3 and shot from 20 yds., the Turkey Supreme won....#5 1 3/4 oz. 3''.
You have to know what works best in your set up before entering the woods...borrow some loads if you need too.
