I had a pretty good idea on what the usually suspects would be when I asked. But there was a couple surprises. The main ones being the 63 grain Sierra, and the 70 grain GMX. With the current run on components going on currently, the only one I can find in my town is the GMX. Local store has a bunch. So will give them a whirl. But fully intend on coming back around and testing most of the others. Mule deer, in your experience how goes the GMX compare to the Barnes monolithic?
