I quote Héctor Medina from the lead recovery thread:
"And, sometime soon, we will get some 0.25" cal pellet molds made."
You know someone was going to ask about this so let's get on with it! What size, weight and design of pellets are you thinking about? Are we talking single, double or sextuple cavity molds?
In another thread you poke fun at those who enjoy casting bullets: "For those survivalists/die-hard Walden-pondians, the 0.25" cal is the smallest caliber where you can reliably cast decent, light, pellets" but since you brought it up I'm beginning to think you might be the Walden-esque of anyone here!
More seriously it does sound like an interesting project to compliment the .25/460 project.
