9.3x74R neck sizing
9.3x74R neck sizing
I am new to reloading and have gotten conflicting advice on whether I should neck resize or resize the whole brass? I am reloading 9.3x74R and .300 Win Mag.
The .300 is for a bolt-action and the 9.3 for a double rifle.
The brass will have been fired in the same rifle that it's going back into.
What is the preferred method?

Andre MertensI do partial size 9,3x74R cases to avoid early case separation. In the present case the goal is NOT to better accuracy as I do with my bolt action rifles. Consequently, I don't go as far as reaching headspace "0" (= feel the rifle close on the case). Doing so may result in staining the action and getting the rifle off face. I do bump the shoulder slightly, just enough to allow the action to close without strain. I started doing that years ago after getting incipient separation of FL cases around 1-3 firings and have since greatly increased case life.

3 shots do not make a group, they show a point of aim or impact.

Andre,
Could you tell me how you "Bump the shoulder back"?
Is this just a partial re-size with a FL sizing die?

Andre MertensRight Rusty, partial sizing with a FL sizer it is. I touch the shoulder ever so lightly, just barely enough so as to allow closing the rifle without "feeling" the round in the chamber.

Andre,
Thank you for the explanation.
