    Since Remington and Winchester primers are so hard to get, what is everyone going to? If I buy Federal or Nobel primers can I exchange them for my Win 209 shells that I am loading? Just wondering.

    Short answer, No. longer answer, if you check out the loading manuals available online, you will probably find other loading data for other primers using your current components.

    I currently use Rio primers and load them as Federal 209A's. Not my suggestion, just telling you what I use...

    Primers are not usually directly interchangeable. Swap the wrong ones and you could be way over normal pressure limits. If you don't have data for the EXACT components you are loading, be careful. That said, if you start with a load that is around 8000 PSI, you might be able to get away with it. Just remember that the pressure can increase, decrease, or stay the same. Velocity is also not a good indicator for pressure. Velocities canb actually go down while pressures go up. Some primers are a larger diameter than others. There seem to be two different sizes these days. The US standard 209 and the european oversized 209. Rio, Nobel SPort, and the Fiocchi 615 are larger. The usual Remington, Winchester, Federal, Cheddite, and Fiocchi 616 appear to be the standard US 209 size, with some differences in the profiles/contours/tapers of the primers.

    Some primers can increase/decrease pressures by many thousands of PSI. Some will only vary a few hundred. If swapping primers, stay away from the higher pressures and you'll probably be OK. If someone tells you that Brand X is directly interchangeable with Brand Y, ask to see the data to support it. The only valid claim for a direct substitution was the Nobel Sport for the Winchester W209 by Hodgdon Powder. I would take that to apply ONLY to their powders and listed data.

    There is also the option of sending a few samples out for pressure and velocity testing. Some primers have very little data to go on, so that may be the best way.
