hello, i just started reloading the other week with a mec jr, its great , i use sts shells and i call them green gold, i was wondering i load them with 16.3 grains of 700x and i use 209 cheddite primer with a grey claybuster wad with 7/8 number 9 shot , my question is about changing hulls , i dont want to take these shells in the bush when i shoot guys with my friends becuase i lose them , its easy to pick them up at the skeet feild and trust me i do , hence the green gold , i have some canadian tire hulls and some wallmart hulls, people tell me their not good for reloading but can i reload them once with the same recipe i have for my sts shells and still get the same effect, that way i can shoot trees and not have to pick up the shells, thanks
