I picked up some 7mm 168gr SAAMi hydrids, after the initial testing I was in short tickled, 2nd outing trying different primers one primer stood out so well my grouping mirrored my notes from the shooting bench! I.e. called one 1/2" left and 1/4" low, another good center bull, another 1/2" left, another 1/4" low ect. That's just what measured on my 200yrd target. These things shoot waaaay better than I do!
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
