I worked my load data up for a 7mm rem mag. Once I had the most accurate load at 100yds (62.5gr H4831SC jammed .012") I then shot the load over the magneto speed.

2951,2931,2949,2933,2949.

Basically 3 at 2950 and 2 at 2930 SD is 9 ES 20

Looks for advice, any quick fixes to close the 20fps gap? Just seemed odd its so distinct. Up powder charge/primers?? Or call it good and shoot it at distance.
