Like I posted earlier, the reason some people expereince 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 epople get different results. We don't expect each barrel to like the same exact load, so why should we expect that Brad X powder will act the same for everyone?

AND:
Temperature
Humidity
Bullet weight
bullet jacket
bullet bearing surface
rifle twist
primers
cases
seating depth
temp of barrel
temp of chamber
temp of loaded round before firing
and on and on and on........ with any # of many many different variables that can and do effect pressures and thus effect velocities, accuracy & POI.
Seems to me to get good reliable test results consistency in the reloading process is the key. 163bc
