    Need one of you bright guys to help me out here. I just bought some Federal 200 small pistol magnum primers (since that was all my local shop had) but can't find any .357 loads using them in my current Speer, Hornady or Nosler books. There must be a manual out there someplace. And I've e-mailed Federal earlier today. Anyway, if anybody knows of a manual, please let me know. I will also post whatever I hear from Federal. Thanks,

    My Federal 200's are small rifle.

    That said, if they are small pistol magnum primers, just use them in place of your regular primer, unless you are running max loads, then just back off a bit.

    I use the Fed 200's interchangably with CCI550 primers for small pistol magnum loads. They are a bit warmer, so you should reduce load a touch and test if you're on the high end of your charge. If you're middle of the road, I wouldn't worry. I've never had issue with them in the mid range.

    A little research shows Federal makes a #200 small rifle primer & a #200 small pistol mag primer. I wonder if they are the same primer with a different label?

    Used up old primers.

    Not to hack the thread, just a note. I got almost a full tray of older Federal Small Rifle Bench rest primers in a trade with other items. They looked rather rough inside the tray=dull+dusty/dirty around the anvil/primer mix. I thought waste not-want not. Loaded them up in some 9mm, 124gr hard cast, with #7 A-A powder. They shot just fine, with no miss fires, or FTF/FTE. ==I just HATE to throw anything out that MAY be usable.:banghead::what:

    I'm not seeing two different Federal 200 rifle & pistol primers.

    According to Lyman # 49, and Federal website.

    Federal Premium® Gold Medal® Centerfire Primers
    A GM205M is Sm Rifle Match.
    And GM200M is Sm Pistol Magnum Match

    Federal® Champion™ Centerfire Primers
    A 205 is Sm Rifle
    A 200 is Sm Pistol.

    Thanks for the replies. Walkabout, rcmodel - I think at one time the Federal 200s were labeled as for both small rifle and small pistol magnum. In fact I recall seeing the photo of a box lid that was so marked on a forum someplace in which this was discussed.

    And Federal just answered my email saying that unfortunately they don't publish reload info. And they didn't mention a manual that uses Federal 200s in their tables.

    I'm willing to use them in place of CCI 550s and cautiously build my loads as per my Speer manual, but it sure would be nice to find a reloading guide that specifically mentions Federal 200s for .357. Anybody know of one?

    At one time, Federal recommended their No 200 small rifle primer for .357 magnum because they did not at the time make a small pistol magnum primer.

    Specific recipes these days? I doubt it.

    Much ado about nothing.

    Use data for any brand Mag primer if that's what you have.

    There is not enough differance between them to make one little bit of differance.
    You have to work loads up from starting data anyway.

    PS: Even if you have the exact same cases, bullets, powder, and primers called for, they are not from the same lot numbers used in the data. There is as much or more combined variation there then there is in primer brands.

    Fed 200, 205, and Match 15.25 per K for the 200's, and I thought that was high at the time! I think I paid 24.95 for the CCI primers marked 9-08.


    Yep......just use them. :)

    RamShot lists Fed 200 SP mag primers in their Load Guide Edition 4.2.2.
    Of course, since this is their load data, they only list their powders.

    Ky Larry: So does Edition 4.3, which I've just downloaded. Many thanks.

    The right way.

    Work up a load with those primers. If you need tips on how to, do this: Use data for any of the primers and bullet of the same weight you want to use. Data can be had from the various powder companies or in any of the manuals you mention.

    Put together 6 to 10 rounds at the start load (IE at 10% below maximum) and 6 to 10 at each subsequent 2% increase (IE. 8%, 6%, 4%, 2% below maximum). Take them to the range and starting with the start level rounds shoot them and check for pressure signs and accuracy as you shoot each susequent batch at the next higher charge level. If pressure signs appear, the pervious charge level is your maximum. If you find a load that's particularily accurate without any pressure signs, that would be the charge level I'd load for all my rounds using your Federal primers and that particular bullet.

    Change any component and you should do it all over again.

    Like the others have said, the Federal and CCI small pistol Magnum primers are so close in performance there's really no reason to worry. Unlike shotshells using the exact components listed in the load data for pistol rounds is much less critical.

    BTW, which powder and bullets are you using?

    BTW, which powder and bullets are you using?

    Mainly H110 with Hornady 35750 HP and Unique with Hornady 10428 SWC. All with WSPM primers.

    Well the Magnum primer is almost a necessity when using H110 but IMO you will get better results using a standard primer with Unique.

    I also use both of those bullets. I like the Hornady 158gr XTP/HP bullets. They are a tough bullet that can be driven harder than you would want to push them. I also like the 158gr LSWC/HP Hornady bullets. I use them to make my FBI replica rounds. The lead is soft enough to expand at the velocities generated in a .38 Special +P. I use HS-6 in the .38 Special +P reloads.

    ArchAngelCD: I forgot to mention that I also use CCI 500 primers with Unique. I reload for .357 in revolver and my Marlin 1894C lever. And yes - both of those Hornady bullets are great.
