I’m curious whether the loads for the Nosler and Hornady from Creedmoor Sports are very accurate and precise loads
I don't recall running anything through my rifle from either Nosler or Hornady that had me going WTF? RPR in this case.
Rather, they've done better in many cases than my hand loads even though they were showing greater SD and ES. I've tried a bunch of the different Hornady's including the Hunter and all have been pretty good. Hornady out to 600 all day. Hand loads to ~1K and would suspect the branded ammo would be fine, too. Sensitivity, for groups, seems more aligned to the monkey than the ammo in my case.
Bulk packs, don't know. Sitting on the shelf. Are you thinking they are seconds, getting knocked around, or something?
