Some of us make 2" "FourTen" cases out of .444 Marlin brass. They need to be treated like any other brass cased shotshell, and the loads worked up very carefully "from the bottom" because there is little load information available. The brass lasts forever; I'm still using the original 18 that someone left on the rifle bench at my gun club and have reloaded them at least 5 times each.

Or IS there tested loading data out there? Anybody know of a source for 2" plastic or brass .410 reload recipes?
