Best load I've worked up:
Winchester Case
70.0 gr IMR 4831
180 Grain Nosler Accubond or Ballistic Tip
Fed 215 Primer
3.332 OAL
This produced consistent sub MOA groups out of a Winchester Model 70 Classic. Best three shot group I've shot at 100 yards is .424".
Another load I like that gives consistent MOA performance:
Winchester Case
71.5 Gr Reloader 22
180 Grain Nosler Accubond or Ballistic Tip
Fed 215 Primer
3.332 OAL

This loadis from theold IMR reloading guide: It isa maximum load.
ARemington 180 grain Core-Lokt bullet:
A Winchester case:
A Winchester magnum primer:
75.5 grains (compressed) of IMR 4831:
That load makes sub moa groups when fired from the 28" barrel of my Mathieu. It also groups well when fired from my Ruger 77.
