264 win mag (help!)

[GregShooter]

I'm having a hard time getting a 264 Win Mag with a 9 twist barrell tuned for a 130 grain hunting load. Wanting to shoot a 130 grain Accubond or Swift Scirocco. Any velocity is OK with me; looking for sub 1/2" MOA accuracy however.gun)

Go ahead and list what you have tried along with your whole load tuning procedure. Also your test range and the rest you are using along with the rifle your shooting.

When I had my Shilen barrel 1/9" twist rifle I found it would only shrink groups burning H1000. I don't remember the charge weight, and Win large magnum rifle primers.

Berger VLD 130s & 140s take a 1 / 8. What bullet are you using?

Will run just under 1 1/2" groups @ 300 yards on average. Have shot 6 whitetail deer with this load from 80 to 250 yards all once shot DRT.
