A couple months ago, I picked up some Federal .410 3-inch shells. Both came in the same style box, but the crimps were different, one standard, the other with an old-school cardboard end. I've never reloaded...do you think that cardboard crimp affects the spread?

Federal .410 shell crimps

Gotcha, that makes sense. I was just curious if it'd be noticeable on clay or small game. Sounds like it's mostly minor, but still fun to see the difference at the rangeYeah, that old-school cardboard crimp can make the shot a bit tighter at first, but once the pellets leave the barrel, it usually doesn't change much. Still cool to notice
Theoretically, the folded crimp should deliver better patterns than the roll crimp, due to the cardboard top wad of the roll crimp interfering with the shot column.
One thing that tends to overshadow the crimp type is advances in wad/shot cup technology. The fact that most modern shells employ both folded crimps and better shot charge protection can make it difficult to simply compare crimp types.
With a .410 and the typical/customary full chokes most .410s come with, the slightly more open and larger patterns with the roll crimp may actually improve bird hunting success rates for some shooters.
