I'm pushing my 178's with 42.5 grains of 2208. I only tested as high as 43 gr (still have some 43.5 in the ammo box I never tried). Lapua brass in a Brno ZKK601. I'm waiting to chrono the load (expecting around 2500fps), and I am re-reloading the same group of cases to see how long they last, as I may be getting a bit more case head expansion than ideal. I also had to trim a handful of cases for length when loading the last lot.
