    Yes with exceptions, if you follow load data carefully some loads for 357 call for small pistol magnum primers. It depends on what powder is used.

    I use mags in everything to eliminate the BS. It doesnt matte ras long as you follow proper loading procedure and watch for pressure signs.

    It makes very little difference in pistol ammo, but sometimes ill find a rifle load that will shoot twice as consistent with a std primer, all else being equal.. And to be fair, i have found opposite results as well. Thats all part of the testing process. And all of the fun IMO.

    NO! and you are not supposed to use the 1 1/2 primers in high pressure rounds like the 9mm and 40 S&W either. Says so on the box.

    And here.

    In pistol cartridges, the 1-1/2 small pistol primer should not be used in the 357 Magnum, 357 SIG or the 40 S&W. The 5-1/2 small pistol primer is the proper selection for these rounds.

    In the last 2 speer manuals some of there 357 loads call for reg small pistol primers. I've try ed 2 of them one with 2400 powder and the power pistol loads work better without mag primers.

    Primers affect pressure - either up or down. If your'e in the middle of the suggested load range it may not matter, but if you get to either end then you're best to used exactly what was used in the book.

    Thanks everyone,
    I load mostly in the middle range of the 9s and 40s so I guess it'll be the same for the 357...
    I'm surprised to find the Same bullet for the 357 as the 9mm
    Precision Bullets 125gr. .365Dia.
    ???Would you crimp these loads???

    .365" dia is 9mm makarov. You mean .356" I hope.

    and a .38 spec/.357 mag should be used with bullets of .357-.359" dia. 9mm and .380 used with .355-.356" dia.

    Crimp is really the wrong term, what you need to do is use the crimp feature on your seating die or a dedicated crimp die to remove the flare plus maybe a thou or two more. It's not really a crimp, just removing the flare.

    Tks Steve,
    I do use the seating die to remove the flare an I see a very slight change after seating the bullet.
    Thanks Again,
    Ron

    A couple weekends ago I loaded my first .40's using some Rem. primers I bought back during the drought. I read this yesterday & when I got home & checked-sure enough they were 1 1/2's. These were loaded a hair above starting load.What can happen if I fire these in my H&K? Do I need to pull these bullets & can the brass? What good are these primers? I'm tempted to can them too. I thought a small pistol primer was just that-Thank's for any input-Dave

    More improtantly, what handgun will they be fired from?

    I wouldnt think the load is too hot, seems pretty mild to me according to data i find in hdy 8th and lyman 49th, if they are gonna be fired in a good strong handgun then id say go test a couple and see.

    The problem with the rem 1.5s is they are very thin so they will be easy for old worn out small pistols and revolvers shooting older low pressure cartridges.

    They can easily rupture in cartridges with more than 20K psi working pressure. Theyd most certainly rupture in a glock because of the goofy shaped firing pin hole, might get away with shooting them in a 1911 style or a springfield XD, Ruger Pseries, or S&W m&p series. they all have fully supported firing pin holes, in fact the XD and M&P series both leave spring tension against the firing pin to help support the primer.

    The .40 S&W is around about a 23K CUP MAX cartridge.. Your loads are slightly below minimum listed in the Lyman 49th for a 180 gr bullet which is listed with a 20,400 CUP pressure level.. Cast lead data lists 4.3 gr to start under a 175 gr bullet at 16K CUP, so I think youre on the high side of the pressure tolerance of the rem 1.5s and should be ok.. Just test a couple carefully first and closely inspect the spent cases.

    Thanks JLA, The model of my pistol is a H&K P2000SK & come to think of it I did use these also to load a hundred 9mm's over W231 & 50 over some Titegroup for my Glock 19 & Kahr PM9. The only old guns I have that use small pistol primers are a Walther P38 my grandpa brought back & a early 80's Charter Arms undercover. For future reference do other primer makers have these differences? I'm kinda frustrated since I might've wasted time & components-Dave

    Agreed! Many new reloaders will think a real crimp of some type is necessary when told to use a crimp die, and this usually leads to chambering/OAL problems. I've suggested many times we change the name of the term and/or die from "crimping die" to "mouth re-forming" or de-flaring" or "mouth straightening" die. None of my 45 ACP rounds (been reloading them for 9 years) are ever crimped. But all of them had the flare on the case mouth straightened by using a "taper crimp die"...
