Mule Deer,
I am in the process of having a 330 Dakota built and there is little handloading data available. On loaddata.com there is some older Barnes #3 data with H4831 and some Nosler data using H4831sc. I will be using the Berger 250 Elite Hunter and my question to you is, is H4831 the optimum powder for this case? I prefer to stay with "H" extreme powders or any known temp stable powder. Thanks!!
