What SD and ES should I expect when reloading .38 Special? MY chronographed .38 Special reloads have an average SD of about 31 and an average ES of about 100 when testing 10 rounds. Should I try adjusting my loads and/or technique to get a lower SD and ES? I am using Berry's 158 g bullets with either 5.1g Unique or 5.5 g Longshot. All rounds go bang and seem reasonably accurate. Thank you.
