I have always been frustrated by the number of powder choices for a given cartrige. I am trying to work up a load for my 260 rem and would really appreciate recomendations for my 260. I want to use the Nosler 120gr BT bullet and the Nosler 100gr BT. I am shooting a rifle from the Savage custom shop. It is a heavy 24" barrel. I mainly use the gun for target shooting so I want the most accurate loads. Thanks.
