[QUOTE="jshepherd61, post: 1336307, member: 93960"] Many ways to tighten up your SD once you have the load worked up. 1. Start with the case and fill, first by sorting to keep cases the same by fill volume (grains of water) 2. Ensure they are trimmed the same length. 3. Load cartridge length from ogave to base not OAL (most projectiles are closer in measurement from ogave to base than tip to ogave) this may change your COAL unless you're using quality match bullets! This ensures the same case volume. 4. Weigh your projectiles even though you may have 168 gr VLD (example) not all are exactly 168 gr. 5. Double weigh your powder on two different scales. 6. Remember you will always have some SD just due to progressive fowling after each shot! I'm averaging a SD of 2 to 5 on most of my loads, you will also expand your SD if full length sizing vs neck sizing. [/QUOTE]
