We load for 8- 30-30 rifles here and our loads consist of the 160 FTX and the 170 Sierra FN all loaded with LeverEvolution powder.
For gift giving my kids/grandangels are known to buy component bullets for me and have been able to find only the 170 Speer Hot-Cor FN for me several times. I load them with my stash of W748 in RP cases with RP primers and they are every bit as accurate as the Sierra and the Hornady FTX, though they have a different POI. I haven't used them on deer yet, just practice, but would not hesitate if the others were not available.
I think Speer are ok bullets.
