Has anyone tried the 220 gr Berrys 300 blackout sub bullets?

With the Amax bullets being gone, the next cheapest is the 208 ELD, and the Berrys are $100 cheaper per 1K. I will just be making subs for plinking, but before I buy these, I just wanted to see if anyone had any experience with them, accuracy at 100 yards, consistency etc.
