SD numbers climb and are all over the place without using a magnum primer. It all depends upon what powder you're using.

YMMV, but in my case, it works.
I tried it because he mentioned H110, until that time I hadn't used it.
Case sizing and crimp play a big role, without this the numbers bounce all over the place like you mentioned.
I get no unburned powder, very accurate and consistent results.
