Those are the 2 primers i prefer. I normally just use the Win209 but my new plug will be headspaced to be able to use Fed209As better. My DISC Original is the "loosest" of my Knights and gets no crush with a Fed209. My new plug will give me about .003 crush with the Fed and about .006 with the Win in that rifle. I will get a bit more in the 54-120.
Since the Original 45 is mostly for sabotless i think the Feds are a good idea. My bare bullets load pretty loose. I cant use the Feds now without dry firing to remove the primer which is a bit annoying.
