I just use standard s&b (Sellior and Bellot) small rifle primers in my 6.5 Creedmoor Lapua brass loads.
I tried the CCI 450 with my accurate load for 143 Eld-x and got worse SD and ES and accuracy. Changing nothing else except the primer.
This is not to say that that a different load recipe might deliver different results.
I actually got slightly higher velocity using standard primers with the same load. The standard primers showed createring way before the CCI 450 primer did. I could go another full 2gr of powder before I got similar createring on the CCI 450 as they have thicker cups.
