I have an AR in the 300 Ham’r, and it’s a great round for the use you describe, or deer. I wouldn’t hesitate to put one together. I’m generally pushing 125-130s to 2400 or a little over. With the right bullet it should do well. If the mini’s mag can take over 2.26” long rounds, you’ll likely get a little more performance, assuming you can seat to the lands.
