Have a 28 Nosler and have bullets that have keyholed and came apart as close as 100 yards. A few have completely missed the backstop at 100 and the box was approx. 18”x36” and nowhere to be seen on paper. This has happened with 2 different people loading with different dies and shooting on their own. Loading Retumbo 78.5-80.5 grains and approx. 3070fps-3180. Didn’t experience this shooting the 195’s and all shots always accounted for. Have seen puffs of dirt randomly on ground or hill away from target to verify they’re exploding. So at 300+ yards some seem to just vanish and apparently blowing up in mid air. Anyone else experience this with the Hornady 180 ELD-M? Some have shot pretty good groups at 100 but seem to not want to make it much further. Full custom from reputable competent smith. Defiance action, Proof carbon fiber w/1:8.44” twist, manners stock, Jewell Trigger, all high end components.
