Something moves inside when I shake it. Is this a hollow point packed with BB’s?
I don’t think so, but the hollowpoint appears sealed for a reason.Or is it a wooden wedge? The purpose of these big solids would not have been enhanced by BBs. They were intended to knock down big things and the process didn’t require any loose BBs AFAIK.
Could it be some wadding that has dried out over the years? Or perhaps the charge (BP?) has consolidated into a single lump. BP has a habit of doing that.
