Just got back form the range the 300 AAC works great but I do have to step up on my load to 17.5 grains of H110.
I had 3 failure to ejects out of the first 50 rounds with 17.2 gains.
The last 50 rounds ran flawlessly they were a little hotter.

I didn't have a spotter scope with me so I could not see where I was hitting at 100 yard so had to sight in at 75 yards.
