Posting those side by side like that is even better to help folks make wise choices as a starting point in trying to get the most out of their guns. They still hopefully will do their homework, but these pattern pages help folks to have at least a ball park idea of what they might can expect from a certain barrel/choke combination.
I love indian creek, but as your pattern shows - many times that .555 just leaves too much to be desired in the outer part of the twenty ring. I can only imagine how many birds have been missed in the heat of a moment with that type setup and the bird at closer ranges. Have you tried a .562 or maybe even more so a .570 IC out of that gun with the same load? Don't waste your ammo for me, but if you have shot either of those, especially the .570 IC, I would love to see your patterns with that same load out of your Franchi. I bet the .570 IC out of your gun will shine. But there is nothing wrong with your Trulock patterns even if you don't test any further. As always, I love to see your results.
