Cci magnum primers v standard

Ok for a long time I was using cci 400 in my Palma brass. Then I went to cci 450 magnum. Question I have had anyone done a test to see how much of a change in velocity the 450 gives.

Pico,

The velocity change will vary from load to load, from all my primer tests I have seen that magnum primers in palma brass result in higher SD ES figures, I currently run federal 205GMM with my current load, but have found the bog standard 205's work better with some powders.

Magnum primer doesn't necessary mean more power(velocity) I can just refer to it has a thicker cup
There has been some great articles on 6Br.com in the past

On accurateshooter some have found some batches of BR4's were hotter than 450's. From memory the rem 7.5 was also shown as producing a larger reaction than the 450. Never had an issue with 450's or BR4's in any BR or Palma case application.
