Curious to see what your rifle reads off that. Sounds very similar to my initial development with the same rifle (except I used 140gr Nosler Custom Comps). Had to get up to 59.0gr to hit 3k fps. Stopped there cause I was satisfied but never found pressure. Also seated way longer than SAAMI. Don't remember COAL exactly off the top of my head, but its way out there to achieve .035 jump. Plenty of room in the mag on those rifles tho, I can still mag feed whatever my super over length dimension is.I haven't tested it yet, but
Winchester Large Rifle Primers
H1000 (4 diff loads from 56.5 thru 58gr)
Hornady ELX 143 grain.
I've been reading and it seem when you are shooting copper like Barnes or Hammers, you see some improvement when switching to Magnum primers.
