I load a little bit for my 410...I use either H110 or Alliant 410 powder (both powders throw an acceptable weight with the same bushing...I can't remember exactly what the grain weight is, without looking in my book)
Considering that a box of 410 shells is about 5 dollars more than a box of 12 or 20 gage, it only makes sense to reload this caliber!
I would load more for it....but the only gun I have is a "Snake Charmer" survival gun....hardly a skeet or hunting gun by any means. Still, I like to take the 410 out in the boat, and launch clays and try to hit them with that little gun, just for a challenge. (Yes, I have a skeet thrower mounted on the bow of my boat....it fits right in the pole mount for the bow seat...and I rigged a foot pedal with a cable, to trip the launcher, it's a blast!!)
You can purchase a MEC loader for about 175 dollars, BTW
