I love the Match Burners in my 6.5CM. Haven't been able to source them locally for my .223's yet. But the SMK's work so well, I'm not a big hurry to find them either.Haven’t tried those. I do use the Barnes 52 grain Match Burner from my 20” FN barreled upper. Shoots great and very flat.
Stay away from the 75gr Hornady ELD-M's, unless you like feeding bullets one at a time. The suggested COL on those makes them too long for a magazine.The 75 grain Hornady is commonly available. Maybe that will work.
