Hi guys do you H322 or Benchmark in medium sized cases for CB loads to produce moderate velocities?

e.g. 6.5x55, 30-30 or 375w.

H322 is listed for jacketed in the 375W 27.0 1,603 fps, lower for cast 1400fps?

Benchmark is listed in the 30-30 for jacketed, 25.3 1,894 fps, lower for cast 1400fps?

Neither are listed for the Swede, but then H4198 is listed as the slowest cast powder and H4895 is listed as the fastest for jacketed! H322 and benchmark are both in between!

Is there anything about these powders or situations that could make them behave odd in reduced loads? For example in the way H110 does.
