What cartridge is getting those velocities?
When you got the 0.56" lower impact @ 300 was your sight-in Zero POI the same with both bullets?
In both barrels all Nosler offerings Shot exceptionally well in my way over bore 270.
In the aged first barrel Bergers were on the verge of coming apart. That is, could not group w/any load.
The new barrel shoots Bergers and the Noslers pretty darn identical with the edge, though very slight (< 0.1 MOA) going to Nosler
Due to bc and energyAnd accuracy I Shoot 169.5s.
However, IF I can get the same levels of velocity and accuracy with the 150 ABLR as I get with 150 Ballistic Tip, it's gonna be the Nosler ABLR all the way!
The hard spot is finding some,
