Ok, so I get the idea of starting working up my load from the bottom (recommended start load in the book) and I agree that this is obviously a good idea.
I'm planning on reloading hornady sp interlock 150gn .308 with varget.
In my lyman book this combination has a start load of 42.5gn
I asked someone the start load for this combo from the hornady book and it's 35.9 (with a much lower max load than in lyman)
which figures should I use as a guide?
