Estate shotshell hulls

[dovehunter]

If it were me, and in the case of really light target loads, I probably would just experiment using different plastic wad columns and appropriate powder charges that, when coupled with the shot charge, would permit a good crimp. I know this is not "strictly by the book" but I have done it before - but only with really light loads - and have never had a problem. Normally though I only buy factory shells for which I have published loading data. If you're worried about it though, I'd just toss the empties.
