Does anyone make a decapping die tall enough to fit the 450/400NE 3" case? My Lyman decapper does not, and in fact belled two of my cases badly last night before I wised up.

I'd rather not deprime using the full length sizing die as my reduced loads using Trail Boss powder don't expand the cases (Horndady's) at all.

Try the Lee wbsite Oregon45. I deprime before washing cases and beleieve the Lee will work for you. I use on .416 Rigby.

The Lee does not size the case at all.

Call Huntingtons and ask for help. He provided a decap die and an extra stem for my 450/400 3 1/4 for a very modest cost.

The larger of the two Reddings should work.
