I think where differing in opinion stems from pellet count. I'm pretty sure in Brads opinion you are not achieving 100 pellets or even 80 in a 10 inch circle at 60 yards. Some would say this is the minimum to ethically shoot a turkey.

I had this same debate as I did not feel you needed 100 pellets to still attempt a shot with reasonable confidence.

I'm not siding one way or the other as 60 yards does sound far with a 20 gauge but I have never seen your particular set up and Im the guy that was being ridiculed for recalling two accounts of witnessing turkeys being taken at long range.
