    Hi All
    I sat down today to reload some 45Acp rounds and ran into a little snag. I have some plated 200grn SWC that I got in a trade. I know that there not as thick as FMJ's, so what do I use out of the manual to load them? Best I could come up with is I found some in the Speer manual that were marked TMJ. Still a pretty good differance in them and cast.

    So what do y'all use? Cast stats, FMJ stats or somewhere inbetween?

    Next one is 185grn cast SWC. I can't find any info on them in my manual. Is there somthing that I am missing or do I just start out with the info for 200grn SWC and back off of it a bit?

    Oh ya. Win 231, Unique or Bullseye. I have all three to use.

    Thanks
    WB

    It depends on the cartridge and brand of bullets. 44 mag revolver and rainier I load cast but Berry's I up to jacketed. Now for my rifle its all cast data. 45acp and 380 I load as jacketed since they are much slower cartridges. Have had great luck.

    I suggest Bullseye powder using lead bullet load data.

    Lead data, or low jacket data. Most of my plated loads are low end jacket data.

    All depends on the brand. X-treme plated and PowerBond plated can be loaded as FMJ. Other plated are usually loaded mid jacketed/cast data. If you know the brand, try asking the manufacturer what they recommend.

    TMJ stands for "total metal jacket". ie: it is a fmj, but where the jacket covers the base as well so there is no exposed lead anywhere. Not the same as plated...

    Berrys reccomends lead bullet data. If you cut into one of the plated bullets, you will see that the copper really is a thin layer.

    Curious, for those who load a lot with plated bullets, how would you tell when working up a load when you are pushing the plated bullet too fast?

    Berry's recommends lead data.
    Rainier recommends jacketed, staying 10% below max.

    I like loads that satisfy both methods, that is somewhere above the starting jacketed load so you don't stick one in the bore, and below max for lead or 10% below max for jacketed data, whichever is less.

    I've found that plated bullet velocity closely matches the predicted jacketed data from Hornady in .45acp, .40 and 9mm.

    I used to use lead data until I stuck a .357" plated wadcutter in the bore of my revolver using starting lead data. Since then I never go below starting jacketed data.

    Not much danger of that in a .45 auto, but plated bullets do have a lot more friction than lead.

    I use Berry's plated a lot. Berry's says to use lead data. So take that for what its worth. I usually use low end jacketed recipies. However you mileage may very. use this information at your own discretion.

    Same as lead in .45 but I am using it with Longshot almost to max with 180gr plated loads (7.1 gr) with no issues in my .40 cal. Shooting X-treme bullets in that load.

    Not exactly. To the best of my knowledge, they are in fact plated bullets, the plating is just much, much thicker. A FMJ has an exposed base and a HP has an exposed front because the jacket is a flat disc of metal that is drawn around a core. In order to not have a seam or exposed base or HP cavity, they have to be plated.

    As many posted, depending on the manufacturers' recommendations.


    Rainier Ballistics (.004" copper plating) recommends we use lead load data - http://www.rainierballistics.com/loaddata.php

    Berry's MFG recommends we use low-to-mid range jacketed load data with limit of 1250 fps for their regular plated bullets (up to .008" copper plating) and 1450 fps for their thicker plated (TP) bullets (.012" copper plating) - http://www.berrysmfg.com/faq-q9-c1-How_do_I_load_Berrys_Preferred_Plated_Bullets.aspx

    PowerBond claims thicker copper plating and I have used jacketed load data with good results - http://powerbondbullets.com/about.html

    X-Treme plated bullets have thicker plating (.010"-.012" per longdayjake who sells them) and I have used jacketed load data with good results - http://www.xtremebullets.com/category-s/1952.htm

    Speer TMJ® (Total Metal Jacket) is registered trademark under ATK/Alliant and have the thickest copper plating (.015") and I use jacketed load data with good results.


    Here's 1999-2005 Winchester load data. I have used load data for slightly heavier bullet for my load work up with good results.

    Plated and FMJ are two completely different bullets. TMJ uses the same load specs as does any jacketed, because it is a jacketed bullet. In fact FMJ and, or, TMJ often have a bit thicker jacket than a traditional jacketed hollow point may have. Because of this, the powder charge may be a bit larger than for a JHP of the same weight. So definitely don't use FMJ or TMJ data for those plated bullets.

    As for a plated bullet the data that applies, plated can be safely loaded between lead and jacketed. So if you would take the starting charge for a 200 gr. SWC and a 200 gr. JHP and start in the middle. In other words, if the start charge for the SWC is say 4.4 grs. and jacketed start charge is 4.8 grs. you would want to start some where around 4.6 grs..

    Another option would be to contact the bullet manufacturer and ask for some load data for their bulllet.

    And if the bullet is a TP, or thick plated such as the line that Berrys makes, it can be loaded using jacketed data, according to Berrys. But don't just simply assume that it is a TP bullet.

    TMJ bullets are in fact plated. They are a thick plating that loads to jacketed specs, but they are still made by plating a lead core.

    I think Montana Gold Bullet's CMJ uses the disk at the lead base of FMJ bullets. ATK/Alliant does hold the registered trademark - http://www.trademarkia.com/tmj-73833272.html

    I'm not sure about the CMJs, but I have talked to a rep from speer on the TMJs and they dont use the phrase "electro plated" because too many people latch onto that and lump them into the same group as say Ranier. The Speer TMJ isnt thicker than a conventional jacket, like stated above, but it is similar in thickness and strength. They simply dont like to refer to it as a plated bullet, thats why they use the phrase TMJ. The Gold Dot is the same way, its not a jacketed bullet. It is, in fact, plated also.

    Rainier says to use regular jacketed data. There is a you tube video of someone taking a tour of the plant recently and he asked this very question.

    I've always loaded my 9mm and .45acp Rainier bullets to jacketed velocities.

    BDS. Here is something you may want to add to your thickness tables. The Xtreme HP bullets are thickly plated to about .015" or more. Same as the Speer TMJ.

    Also, after having visited the Xtreme plant and seen how they do their plating, I can see why they aren't posting a plating thickness on their website. Apparently it isn't an exact science which is why they double strike everything.

    Rainier also double strikes all their bullets.

    I load them as lead.

    However, I load them as FMJ in 30 carbine, and they work very accurately. Go figure.
