I shoot hot loads with light bullets from my 6MM and I still get 15 loads from most of them. My .338 W.M. on the other hand typically won't go more than 4 loads before that belted phenomenon problem rears it's ugly head.
My HK 93 ruins brass quickly, the fluted chamber makes for a lot of tumbling and you still get ugly reloads. My .45 L.C. depends on the load, plinkers or "cowboy" loads can be up to 20, but my heavy hunting loads stretch something fearful, about 6-7 loads there.
