[QUOTE="BountyHunter, post: 151421, member: 12"] Couple things not clear here. 1. How accurate are the charge weights? Are they each weighed and on what? 2. Accuracy of the chrony? What type chrono or are we talking chrony chrono? 3. Try different primer first for 5 shots to see if ES comes down. I would start with a F210, then CCI. Many times it will even though not a mag primer. 4. Different powder next. I have not used the U869 but it might be the ticket. If you can find some MRP2 (Graf and Sons and Black Hills are stocking it), I know a standard primer will normally beat the mag in that and it is equivalent to RL25. You must have uniform charge weights for uniform MV and your chrono has to be accurate within its own range. The chrony chronos are touch and go when comparted to an Oehler, so you might have problems in eithe one of those areas. BH [/QUOTE]
