I believe the the blackouts are cheaper by 1/3 I think. I bought Corbons for a year and never got to enjoy my rifle as everytime I pulled the trigger I am thinking ouch $$$. I bought some hornady dies from SSK. 500 brass from Hoser. Now I am a maniac, shoot squirrels, groundhogs, paper, deer, whatever I want, whenever I want. I get to play with different loads. Never think about the cost at all. But,,,,,,I am shooting a single shot encore. I cant imagine shelling out for cartridges spraying with an AR,,, at least not on a hunting outfitter's income.
