I use retumbo with a 200 WC.
Here is what he said -
The heavy load for our 7mm Dakota generally consists of a 175 gr. Swift A-Frame or Nosler Partition. We would recommend starting with 70 gr. H-4831SC and moving up to about 73.5 gr. maximum. We prefer the Federal 215 primer with this load and an overall maximum cartridge length of 3.330".
I have never loaded the 168gr. or 180gr. VLDs for our customers so I don't have any load data for them.
Please let me know if I can help with anything else.
