Winchester only do a run of 32-40 every 3 or 4 years which is why nobody has any!
I may have some 3030 brass that's already modified that I can pass on. It will be mixed head stamps.
I also have a custom mould for a gaschecked 165gn bullet if you cant find any.
ITL had a load of 3030 brass a year or so back.
