But again, to get the full enjoyment the 375 RUM should give I think you will like playing with 375 H&H duplication loads. In a 378 85 grains of Varget is about 2650 with 270 grainers and extremely low pressure and the same load hits 2500 plus with 300 grainers and a bit over 2700 with the 225 grain Hornady. Loads for the RUM will obviously be a bit less powder
Where did you find these Varget loads for the 378?
Thanks
