Yeah, I know that I'm likely going to need to experiment around for what my rifle 'likes'.
The shooter that recommended the Federal Premiums did so based on two characteristics of the bullet. (1) He used to have a BBR and it 'liked' Federals. (2) The stat's of the Premium are almost identical to his custom loads in a rifle with similar characteristics. Knowing that I'm somewhat constrained by budget and can't just buy a box of each brand and type to try, he thought there would be a good chance that the Premiums could get me consistent small groups. But at that big of price difference, I think I'm going to have to try a box of each.
