No one insinuated that it should shoot every single bullet across the entire range of bullets in 270 cal. Reread the post. Now obviously if you try to run a 70gr bullet in your 270 Its not going to work Now I am not sure why Weatherby would use a match grade bullet to test fire a hunting rifle But I will not say that they didn't. That's why I suggested that he contact the manufacturer and ask what type of ammunition they tested the rifle with. Be sure before you ask the manufacturer to fix your rifle that it actually needs fixed. Eliminate all the variables. All the major American manufactures have a disclaimer concerning reloaded ammunition. So when you contact them the one thing you don't want to say is your new gun will not shoot your reloads.
