Larry this is reverse magnumitist at work. If 7K is good then 6 or 5 must be better. Logic of the lazy or ill informed.

I would rather find the load that patterns best, at a decent pressure level, but very few will pattern four or five loads to see if one low pressure load patterns well. When I use to reload for duck hunting I spent afternoons testing loads, perhaps trying as many as ten, to come up with the best one for the gun I was using. Kept notes for each load. Sometimes the pattern would be vastly different for just a few grains change or a wad change. Listed is not recommended in my books. But too many will just see it and use it without any more investment of their time than that.
