What dies are you using as it sounds like the neck tension is all wrong and I usually well always crimp my 303 rounds, have you contacted VV with the batch number of your powder, also with a Magnum primer it equates to about a grain of powder so adjust your loadings I run Fed - 215M in my 6.5/284 and have adjusted the loadings down a grain, and I use Fed Gold Match - 210's in my 308's and 303's interesting thing I will keep on this thread as I use VV in my 6.5 (N-165) and have not had any issues
