What protein do you use in shotgun shells

[Propwashed]

I imagine there is 100's of years of smoking/cooking experience on this forum. I hope you guys won't mind me asking questions on technique for certain cooks.
I am thinking of using Mexican charieso (sp? ) and 80/20 burger. Would breakfast sausage be better than burger?

Chorizo is usually my go-to on those. What else are you putting in them?

Italian sausage works well too. You could mix up some taco seasoning in some ground pork or beef and use that as well.
Key is with these is making them the day before and letting them sit so that the shells soften a bit. You could also use medium ground meat as opposed to lean to help in getting the shells even softer.
