[QUOTE="Idaho Trecker, post: 2309835, member: 67706"] You could just have a slow barrel. I'm shooting the 165 matrix in my 19.5" 270 SS at 2860 with no pressure. I ran them up to 2980 fps but that was just to find my absolute max and not a good load. With equal barrel length I theoretically would be around 3035 fps using 25fps/inch barrel difference. I've shot the 165 matrix and 170 berger in my last 270ss barrel at basically identical speeds with the smaller bearing surface of the berger leveling the difference of the weight. I plan on messing with the 170 next week in the new barrel. I've also been meaning to try the 165 lrab and hope I dont suffer the fate most do with having difficulty getting consistent accuracy out of them. Can you get Hammers up there? Have you checked the twist on your barrel with a cleaning rod to verify it is what it is supposed to be? Was your brass twice fired at least now in this chamber? On the other hand I also am fighting what I would assume at this time to be a problem with an action. I am on my second barrel with the same issues. First barrel was bartlein and now krieger. The action has been trued, new stock (bedded), 3 scopes, 2 bases.... The rifle pressures out really early and is not accurate at all. [/QUOTE]
