I'll be interested in some of those 20 ga loads, though I am not turkey hunter (yet). I want to see what can be done with very light loads for upland game. For example, #11s are 870 pellets/oz, so a half-oz (435) EXCEEDS the pellet count of a full ounce of lead 8s (403) ... what I used for quail for all but the end of the season prior to the Cali lead ban. And the 11's are more lethal.
I could go down to 1/3-oz of 11s and get all the pellets I need. But who the heck has THAT load data, even for a .410!
Just one look at your patterns makes it clear that, um, maybe you don't need ALL those pellets for Mr. Tom, although on a turkey hunt where shooting is limited, WTH. On an upland hunt, one would expect more shooting.
We'll be talking sir ...
