Simplified Reloading - Partisan Style

[CharlesHarris]

The fast burning pistol and shotgun powders mentioned are trouble free in reduced loads.

Military rifle powders recovered from full charge service loads, as also described, are problematic if the charge occupies less than 2/3 of the case capacity, but if that requirement is met, there is no problem.

The dangerous pressure spikes occur when you reduce heavily coated powders in very light charges nwhich occupy less than 1/2 of the case capacity, in which case the charge lies out in the bottom of the case and a greater surface area is exposed to the primer blast.

If you follow the instructions in the article you won't get into any trouble.
