Maybe I am overthinking this too much, but:
For years I have been hearing that HBWC boolits have been used with tremendously accurate results. To me, it is hard to understand how a bullet that doesn’t start out in a properly fitted throat, which I have been told is necessary for good accuracy, can produce such fine accuracy. Is it the fact that it is seated so deeply in the case, producing a higher Powder Fill percentage, offset the throat situation? Thanks for any input guys.
