How sensitive is the Grendel powder column? In other words, are benchrest primers a must for accuracy?

I'm currently using Rem 7.5's in Lapua brass, and CCI 41's in Hornady brass, in part due to fit.
The 41's fit snugly in Hornady brass, but are excessively tight for Lapua (with 7.5's snug in Lapua, but a little loose in Hornady). The 41's are mag primers and produce more velocity (and pressure) versus the Rem 7.5's, although Rem velocities seem a little more consistent.Drifter

Group size is the same.
