Vitahvuori N560 is the most readily available powder where I live and Retumbo is not available.
There is a powder called RS80 by Swiss Reloader which should be between H1000 and RETUMBO, and there is also VV 24N41 which is a .50BMG powder that may do well in the .338 Lapua improved versions with the 300 grain bullets.
Has anyone had any experience with the Vihtavuori powders in the improved .338 Lapua based cases?
