Like I posted earlier, the reason some people experience POI and/or velcoity changes and others don't is likely do to a number of variables such as:

- How hot the load is
- The chambering in question
- The barrel
- Shooting technique
- The powder in question

It should really be no suprise that different people get different results. We don't expect each barrel to like the same exact load, so why should we expect that Brand X powder will act the same for everyone?
