Hi I am going to reload 325 grain cast with gas checks and 425 grain casts with gas checks. I am using Varget powder. i can t seem to find information with these weights in mind. I was wandering if anyone has loaded with varget with these weights and with casts? Can you use cast loading with cup and core and vise versa? This is for a 1895 Marlin Model336. And I would like to keep the pressures around 28000 cup. For the 425 grain Im thinking 49 grains of Varget and for the 325 Im clueless. Thank yo8u Ahead of time for any who can respond and to those who try...
