[QUOTE="hemiford, post: 2837355, member: 72104"] 1. Wrong powder / too much powder 2. Too tight neck fit / case crimp 3. Bullet too close to the lands 4. Aggressive leade angle 5. Rifle bore "tight" 6. ??? Are the following things not really causes of overpressure ? 1. Tight twist 2. Barrel length 3. Type of rifling / groove width, number of grooves 4. Below "minimum" powder loads 5. Headspace too tight 6. ??? Trying to educate myself before I begin handloading. As an example, if X grains of powder Y produces a flattened primer, you could possibly either reduce the powder load, HbN- coat the bullets, or cut a longer leade. Please feel free to add to my list ! [/QUOTE]
