i got a lee classic hand reloader given to me and decided to have 300 brass that i saved from my 30.06 tumbled and try reloading some. I bought nosler 150 grain ballistic tips which is what i was shooting factory. I bought winchester rifle primers and Hodgdon H4350 powder. I started out on the low side of powder and loaded a few at 56grains and 57grains. Both of these did not fill the case but only maybe half and they both fired with no recoil and sounded like a 22 rifle? What the heck.... i must say that i am very particular and am thinking of trying 59/60 grains next but am really doubtful of any better results. Any ideas greatly appreciated... Thanks
