The 215 is pretty much the go to primer for most of us.
Separate your brass by brand. Believe it or not even slight differences in wall and neck thickness can make a significant difference in ES.
If you can get your ES down under 50fps consistently till you get past 1000yds the difference in POI is going to be negligible. It is nice to have it well under that down in single digits but it is rare to get a big magnum that consistent.
How are you measuring your powder? Are you weighing each load or using an auto charger like the RCBS powder measure? If you are weighing each load, what method/brand of scale are you using?
