I am a little concerned. I have loaded three shells. One with lowest stated trailboss load and two with above said powder also at lowest possible load. For trapdoor loadings of course. .405 gr lead bullet. But the lenght of these hornandy cases makes me hesitant. Personally, I think it will be fine, especially since my neighbors gun is a break action gun (like a squirrel gun). But I'd like to get your opinions just because I have loaded them not for myself, but for a friend and because it is an odd cartridge length. I have seated the bullets with the groove right beneath the rim of the cartridge. (it's not called a groove, I just can't think of what it's called off the top of my head)
Should I pull the bullet out a little with the "groove" even with where the cartridge rim normally would be (even though it will look kind of odd)??
