New Buckmark, what should I feed it for grouse?!

So any standard velocity round or hp bullet will work fine for grouse right? Doesn't seem like it's take much more then standard stuff.

I prefer subsonic.  Not as loud and is just as effective.  HP isn't needed.

I have had the best luck with CCI. If you want to get really dialed try buying a bunch out of the same lot and then weight them on a grain scale. They will vary and you can group them by weight and then sight in accordingly. When you run out of that weight site in with the next group. I am talking using the same brand and type of bullets. It works, at least it does for me.
