I had the same problem with a 300 WSM using W760 (which I've read is the same as H414) and standard rifle primers.

After reading everything I could find on the subject, the consensus seems to be this:
Use Magnum primers with ball type powders
Use Standard or Magnum primers with extruded (stick) powders

I know it's hard to make a "rule" with reloading, which has alot of variables, but since applying this "rule", I've had no more click-bangs. I usually test magnum primers even with the extruded powders and still use them on one load for the 300WSM with extruded powders - because that gun and load groups better with magnum primers.
