[QUOTE="QuietTexan, post: 2639029, member: 116181"] SD only matters for large sample sizes. It you're going to put less than 10 data points into the population don't even bother with it at all. If you want to truly care about it you need to chrono every shot over multiple sessions and and conditions to get a true load SD. Or in your specific case, multiple cold bore shots over multiple range sessions. Anyone can get a 3-shot SD of 1fps in a single range session. A correctly tuned load will be sub-10fps for dozens of shots over time in different conditions. [/QUOTE]
