Hi Chuck,

There is no accuracy lost to correct full-length sizing, and it does add a measure of security. The reason I usually neck size my hunting rifle practice ammo is for convenience; it's easier. In fact, and contrary to popular wisdom, many world-champion bench rest shooters full-length resize. When I bought my most recent bench gun from Clay Spencer (Stolle/Hart/Six), he not only recommended full-length resizing, but sold me the 6mm PPC dies. The sizing die uses a bushing so that the neck is only sized the correct amount for the fitted-neck chamber; there is no expander ball. But the case body is sized and the shoulder is set back slightly.

My hunting ammo is full-length sized using ordinary dies. I know it will cycle through the gun under all circumstances, and as I have several guns in most chamberings, I don't have to worry about segregating my hunting ammo. I recommend full-length sizing your hunting ammo.

Take care, Tom
