Is there any reason one should not use magnum large pistol primers with unique powder in the .44MAG? It would be nice to only have to get one kind of primer.
If you aren't loading some slow ball powder like H110/W296, you don't need them either.
My typical use of Unique and Univeral are in applications where I'm far from approaching maximum loads.
Substitution of a Magnum primer is insignificant. I do it frequently.
Unfortunately, I am using a max load with unique, mostly because of the limitations of the lee powder measure set. I am not patient enough to weigh every charge.
Using a Lee dipper you're probably all right, seems like all the dippers I've used will measure on the light side if used properly.
...try using Winchester primers. They're usable for both standard and magnum loads.
