I still have the Nosler #1 manual, March 1976. The only .257 bullets they offered back then, were a 100, 115 and 117 grain spitzer Partition. Later they introduced a few more, including the solid base spitzers that a lot of guys liked. That was supplanted by the BTs. Know guys that still lament the demise of the solid base selection and hate BTs.
A friend shot his first buck back in the 1970s with a M700BDL in 25-06 and the 115gr Partition. Knocked the buck down, but it didn't stay there. Got up, ran farther down the mountain side and another hunter killed it. Looked things over and the Partition never opened up, went straight through. No bone or vitals hit. Last Partition he ever loaded.
Great bullet for the most part, but not always. Most of the deer we've killed with that cartridge and a 100gr BT, dropped where they'd stood or walked.
