I have RCBS dies (two die set) that I purchased back in the late '80s when I first inherited my 9.5X57 (M1910) MS. They also reform 35 Whelen very easily and properly (after trimming to overall length, of course).

Do your 235 grainers feed through the Schoenauer magazine, or do you just load two at a time?

I have found that if the bullet profile is not rather close to that of the original (Eley - Kynoch, DWM) specifications, a third round will get 'jacked' and will not feed.

The old Hornady 3715 (.375, 270g. RN) worked just fine.

Member Kuduae, however, has advised that he has used Barnes 30486 (.375, 235 gr.) while seating them further 'out' to more closely match the finished profile of the original cartridge.

There is now this option for fresh new (not reformed) brass, as well:
