HS-6 is an older and slower ball powder and IMO you should always use a magnum primer when loading with it. A magnum primer will insure a more complete burn of the powder and a more even burn. Any time you can make things more uniform it has to help with accuracy.
Like I have said A LOT on this and other forums, a magnum primer will burn a little hotter and a little longer but it will not create a nuclear explosion. For some reason the word "magnum" scares some people but in reality a magnum is just a bigger bottle of champagne. For example, Winchester's LPP are rated for both standard and magnum use but nowhere in the industry is there a warning to reduce the powder charge when using a WLPP. If there were any chance at all of going over pressure with a magnum primer there would be warnings all over everything, especially in our litigious society.
