Gotcha, I suspect that you are going to find that it’s more the bullet and not the brass that will tighten up your groups. Not saying that Hornady brass won’t make a difference but it’s typically been my experience that a different bullets and powders make more of an impact then different brands of brass.
1 MOA is pretty respectable, the accubonds are a good bullet and some people get Sub MOA results from them. If your looking for a hunting load, I think you’ve got a pretty decent one. If you want more of a target load, a SMK or Match Burner should really help tighten up the groups.
That’s just my opinion
