The reason I only tested 2 different loads is because they were the cheapest

. The Rem Nitro was like $5 for 10 and the Fed Mag Shok was about $7 for 10. Everything else was more expensive and since I'm shooting this stuff in a shotgun that has a a FULL choke barrel and is over 20 years old why bother with the obvious. The obvious is that my limit for shooting at a gobbler is 40 yards under ideal conditions, my patterns have confirmed this. At 40 yards there wasn't much of a difference at all with regards to the number of hits in the turkeys neck area. The number of hits was right around 6 on the red area of the target, which is about as big in diameter as a coffee cup.
I could have spent more money for some of the boutique turkey loads, but it comes down to knowing where the load patterns with regards to the point of aim. I have confidence in the loads I'm using and I'll tell you what, firing turkey loads is not fun, as they do kick quite a bit with my Win 1300. As a comparison, I tried my normal small game loads, which is about 1 1/4 oz of #6 with 3 1/4 drams and the difference is extremely noticeable, both in the recoil and the patterning. The shooting stick idea is a good one, I'll give it a try.
