I bought some of the Speer Nitrex ammo in .270 several years ago. It's topped with the 130 gr. GS, & is the most accurate load I have ever used in my Ruger 77. I've tried Federal ammo with the same bullet, H4831 handloads with the same bullet, etc.; & nothing shoots as well as the Nitrex load. I wish I could locate some on a back shelf someplace.
