Another vote for following the manual's recipe exactly. In the event you can't get the exact primer called for, you can usually substitute a similar type from another company. That is, a standard for a standard, a magnum for a magnum.
There are many good reasons for using magnum primers, but trying to reduce unburned powder kernels is NOT one of them. Unburned powder is usually the result of using a powder below its best pressure window. Either a heavier charge or a different powder are the correct remedies for unburned powder.
