I'm using a mp molds 462gc hammer mold. In deep HP they're about 310gn if memory serves me right and in flat nose they're about 33xgn. These will be target loads as I cannot hunt with this rifle. Which by the way is a marlin Guide gun. I'm using cci #200 primers and lubing with something comparable to nra formula. For powder I have imr4198 and h322. I have load data for both and plan to work up the loads but I was curious if anyone had any tips as this case is pretty big. And with 49gn of imr4198 it looks to have a good bit of room. Thanks
