300 blackout/whisper

[wadea1974]

Does anyone have any reloading data using Sierra 180g spt pro hunter bullets? Using powders such as h110, n110? want to work up a load for deer hunting!

I could not get them to open up. Check out the web site. They fail to open up about where the whisper starts. Just my experience...

Check out Outlaw State, Lehigh, Clearwater Custom, Diamondback Custom. All will open up and there is different wts. Also Barnes makes a 110 black tip that they say is real good.
