[QUOTE="codyadams, post: 2043383, member: 87243"] You bet! I used some in a .338 Norma mag as well, with a 28" tube ran 300 Bergers up to 2940 fps in pressure work up, still no increased bolt lift, ejector mark, and only slight primer crater! The cases were all fine again, no loss in the primer pocket. I have noticed however, Peterson tends to have a little smaller case capacity, so keep that in mind on your work ups. In my .260AI, it made a difference of roughly 1-1.5 grains less for same velocity/pressure compared to Lapua and Federal. I have heard similar reports about the creedmoor line of cartridges as well.
