I found 98 Mauser in very good condition. It has not been changed in any way , I have slugged the bore and come out with .318 inch.
I have started wanting to shoot cast boolits out of it I have the mold, new brass, reloading die's and gas checks but the .321 sizing die has been repeatedly backordered, I want to shoot this rifle to see what it will do.
I picked up a box of 8mm Serria game king 150 gr bullets lable shows them to be .323 inch , Serria manual has a warning about this.
What do I do about this is this bullet safe to shoot in this rifle or should I just wait on the sizer die?
