Looking to work up some subsonic loads for a 400gr cast boolit in a bolt action 450 Busmaster using Unique- anyone have any experience with this?

Not unique, but with Shooters World Blackout and 500 grain bullets. I'm getting good cycling and accuracy.

11 grains of Unique with a 405 gets 1089fps from the 18 5/8" barrel of my Ruger AR.

Tried a handful of 4oogr cast boolits over 10gr of Unique today.

Was just shooting off the back of the truck at 50 yards but accuracy was good, just under an inch and velocity was around 960fps and stable.

Very mild report pleasant to shoot and more energy at 150-200 yards than a 45acp or 10mm at the muzzle.

lar45 what mould is that?
