    The cold barrel zero is correct on my 300WM.How ever the point of impact over a number of rounds moves,this can be up to 1/2MOA after 10 rounds,The barrel is not hot.The barrel is a schnieder 26" H.V contour,after a proper cleaning it takes around 12 rounds to settle down.Should I clean it more often,then may be it wouldnt need the 12 round settling down period.
