These are all of my pet loads. They were what I found to be the most precise in my rifles after extensive and tedious load development. I may tweak the loads slightly as the throat of a barrel erodes, but I don’t typically vary too far from what is shown here.

You should always reference a quality reloading manual and start with the minimum recommended loads, and work your way up. Just because these have proven safe in ...

The OCW method is based on the observation that there are some loads out there (like Federal’s match ammo for the 308) that shoot really well out of just about any rifle.  How can one recipe shoot so well out of so many different rifles?  Dan Newberry believes accuracy of ...
