Was wonderin' about using WC 860 for cast in 35 Rem and maybe .308 and 30/30. Do you have to use full case loads or can you start lower and still get good efficiency and velocity without getting into weird pressure excursions? I've got a small amount of H870 and would like to try it in the 35 Rem with a 200 gr cast to see how it does. Any suggestions as to where to start?
Thanks, Ron
