I am looking at starting to reload for a .204...So I go to a manual or two and they say they used a Remington 7 1/2..Small Rifle Primer....Then I go along looking in some Manufacture handout's..And it say's they used a ...........Federal205M....which I believe is a small rifle magnum primer..OK..I see the same powder manufacture and I also see the Remington 7 1/2 which are not designated on the box as a small rifle magnum primer..So is the Federal 205 a Magnum prime...In the handouts when it does state the magnum primer it is always Fed205M...no other brand...?.I guess what I'm trying to ask ..I see the use of a Magnum primer and a reguar small rifle primer desiganted for the same powder and load data...What is your..thought on it?...Thanks
