No advise from me, but why go from a cartidge so common to one so rare.
curiosity mostly - I have 3 Super Bs and just landed a destroyer with brass and dies .... so 'curious'
I'd rather find a barrel and just swap in/out ... "fun stuff" the Large isn't much different from the Para...
So thats where the Destoryer, went off the EE. It was a nice looking unit.
thanks for the heads up ...Just be aware Destroyer extractors break easily and are as hard to find as an honest politician.Also parts made in various Basque villages so almost everything needs to be hand fitted.
