I bought a couple boxes of these for the .270 and they are fairly accurate. Does federal make their own bullets or are these a 3rd party?

Federal uses others bullets some Sierra and some Hornady and some others too.
In Federals Blue and silver boxed .335 Win mag they use Sierra 225 grain bullets which Sierra does not catolog.

The box in question is the Federal Blue, Power-Shok. 130gr soft point.

Last ones I bought were Speer Hot-Cors. Don't know if they have changed.

same here. I was under the impression that all of the Federal blue/silver box ammo was loaded with Speer Hot Cores.

Thanks much!

btw: "hot core"? any relation to uh, oh nevermind
