About 5-6 years ago I got to do some 3000 yard shooting with a 338 edge +p built by Shawn at defensive edge. Not my rifle but the owner kindly let me shoot it with him for a day. He used the regular 215’s and we managed 3 out of 5 hits on a 30 inch plate at 3030 yards, first shot we couldn’t spot, second we realized the wind hold was off, then 3 shots well within the roughly 1 MOA plate. ES on his loads was under 10. I feel like the only difference is the color of the box and the amount of weight in your wallet after you buy them. Maybe there really is a difference in compound or anvil or whatever but it’s not one that matters in my opinion.
