I dont think they will be that big due to only being offered in one caliber and one grain of weight. They more than likely wont work with the TC line due to them not having the skirt to seal the bore.

What do you mean by this? Why not TC and yet others canshoot. I understood the expansion on the bottom would engage the rifiling? I realize the PB had the skirt, but the thin copper workd same as PB right??
