So after a basic test the rifle (a Ruger Ranch 16" barrel jobbie) is shooting both Hornady 123gn ammo's into 3 shot groups of 20-40mm - plenty good enough for "minute of deer" with factory ammo. I'd expect to reduce these group sizes quite a bit with a tuned reload.
However the PPU was hopeless in my rifle - 60-75mm groups being as good as it got - so thats a bust. Bugger cause its way cheaper than Hornady.
If anybody would like the balance of the packet of PPU to try in another rifle you're welcome - free as long as you report the results here!
