    Wondering how many people are turning to .357 projectiles in 9mm due to the scarcity of .355's ?

    I've resized 158g .357 FMJ down to .356 and ran in 357sig subsonics in the past without issues. I know different barrels and firearms react in different ways and anything non-spec needs tested thoroughly, but at least in my testing I've been successful.. I always drop the load by 10% in case there are increased pressures, but haven't run into issues.

    I've done it but you cant safely load 158 grain bullets in 9mm. It's too long and will bulge the case where the case tapers inside. Even if you run it through a factory crimp die afterwards, the base can easily blow out. I bought a 155 gn bullet caster that makes a boat tail to avoid that problem.

    Yup, I'm not saying to load 158gr in 9mm, just that I did a similar 158gr in 357sig. I just grabbed 2K of 125gr .357 FN TMJs to have on hand just in case.
    Will size them all to .356 and load some test ladders.

    When did 9mm bullets become scarce?

    After a long search on the 19th, I found and purchased 500 HAP 125gr 0.356 bullets. I looked at the same dealer site this morning, Now they are out of stock.

    So they make both .355 and .356 HAPs, are you loading the .356 in 9mm (or other .355 application?). I'm guessing they sell the .356 HAPs for .357 applications (38spl/357mag), so this would be similar to my original question..

    Maybe not as scarce as primers, but price is doubled or more and stocks usually go OOS soon after becoming available.

    My original post should have been qualified as using "cheaper" .357 projectiles in .355 applications. The .357 125gr's I just ordered were $0.06/ea. I can still get in the Backorder queue at RMR for $0.09/ea 125gr .355s, or pay upwards of $0.16-$0.20/ea in most other places I monitor..

    Yeah twiddling my thumbs on those backorders. I’ve got some .355 for loading. About 250 147gr XTP, 500 115gr RMR FMJ and some coated lead 115gr (like 80 bullets).

    I am back ordered on 1000 115gr FMJ and 500 124gr JHP from RMR. Been waiting about 5 weeks on the 115gr and a little less than 2 weeks on the 124gr.

    They’ll get to it. Sadly not as cheap as a few months ago.

    45 is also kind of scarce. I’ve got 1k 230gr and, as usual, got off my duff and decided to get more. X-treme bullets seemed to be the best deal. In the course of 2 days they upped their price twice on 200gr plated so it cost me an extra $10 for 1k. Missed out on RMR’s plated 185 and 230gr. For the like 3 days they had any.

    Learning for later. With reloading, makes sense for me just to have buckets of bullets sitting around once I can get it for really cheap again. Same with primers.

    I make 125 gn bullets that will work in .38/.357 and have no problems with them. I tried 140 gn but there wasn't enough room for powder and their accuracy sucked.

    I’m going to remember that line ;)

    It’s not me it’s the bullet :p

    Of course. It's always the bullets fault. :lol:


    However, it this case it was the bullet. It was a Lee 140 SWC and had to be seated so deep to chamber, their wasn't much room for powder. Additionally, the taper of the 9x19 case was swagging down the bullet so it was having mucho blow by.

    I just grabbed a bunch of all-copper .357 boolits from American. (Double discounts, so about 8.8cpr)

    https://americanreloading.com/en/38-caliber-357-358/2958-38-357-125gr-fn-copper-500ct.html

    They look like the same profile as RMR matchwinner 147gr, but only weigh 125gr all-copper. If that's
    the case they should work great in 357sig, and if not, I'll throw them in my newly acquired 357mags

    I finally received these 124gr all-copper boolits. They are the same physical size as the 147gr FMJ MW and have a more blunt nose profile making them able to seat .025" further out of the case than the MWs. (They are also .356 out of the box, so no resizing needed for 357sig/9mm use)

    Downside is since it took over a month for phucking USPS to deliver them, they are now OOS. I did grab 2K of them and they have a nice specific usage in 357sig loads I have in mind, so I'll put them to good use.

    HMMMMMMMM, did those work in a 38spl revolver?
    The FP on that mold looks big enough to work in my 38/357 lever action also
