[QUOTE="Greyfox, post: 1604074, member: 10291"] One possibility to be checked out is to be sure that your bullets are firmly tensioned in the neck. I had a similar issue years back with my 6mmAR(necked down 6.5 Grendel) which drove me crazy with “random” pressure peaks. The heavier bullets, 107gr 6mm SMK) we’re jamming into the lands caused by the inertia of the rifle cycling , thus increasing pressure. My reloaded rounds seemed fine when testing the seating tension when the tips were pressed against my wooden bench......they weren’t! A switch to Lapua 6.5 Grendel brass with its thicker neck wall fixed the issue. Not sure if this is your issue, but your symptoms might warrant checking this out. [/QUOTE]
