IIRC, the Lee Internet site has updated the checklist about which primers are ok to employ. They now appear to one out FEDERAL exclusively:
CCI 250 – While not marketed as Section of CCI’s “benchrest” series, a lot of say these primers generate good regularity for just a magnum rifle.
I could see the primary difference in the indent still left via the FP. The hooked up pic reveals still left spherical as one that didn't ignite.
