With a little massaging of the first coil the DAA output chute springs works quite well with #12 and #13 adapters but is to small OD for the #14 adapters. Also the 44 mag case does not like the DAA output chute spring very much. DAA output chute spring runs about 13mm ID and almost 15mm OD. But the 44 mag case is 13.06 nominal with a -.25mm tolerance.
Anyway I will order up something to try. Have received three good suggestions here, Aliexpress, McMaster Carr and The Stop Shop as sources, and will check dimensions and pick one.
Many thanks
