    I’m guessing it could be a little bit of both. My buddy had 2 kak barrels which seemed out of spec and low and behold we’re recalled.
    Though in this guys video when he reloads his own with proper size bullets and a proper crimp (factory was sizing down the bullets to .3565” on crimp) the issue is eliminated.
    I hope this whole debacle doesn’t kill off this cartridge. Smaller issues have killed off cartridges in the past.

    I hope so too, but he should offer up a chamber cast to verify the entire chamber is correct as the freebore measurement is never given.

    Call me stupid but how does a case the head spaces off the mouth expand enough to get case head separation? Unless the ejector is holding the case against the bolt I don't see how it would even fire.

    Bad headspace (could be gun or ammo related) or over pressure are the two classic answers. If the chamber has good headspace and the ammo is within the acceptable range (guys have measured ammo over and under the spec-shame on WIN) the next thing to look at is diameters. The SAAMI minimum cartridge case mouth diameter is .370" (.378"- .008" on the cartridge print) and a maximum allowable chamber freebore dia of .359" (.357" +.002" as called out on the chamber print). That leaves you with .011" to headspace on worse case if everything is in spec. Guys have measured case mouth diameters under the SAAMI spec of .370" on factory Win ammo and there have been chambers cut with the freebore step larger than .359". If the chamber step from case mouth to freebore is beveled too much it will also allow the case to wedge in too deep and cause issues as will too large of a freebore.

    I had sent the video to my gunsmith and he said that there is something not right on the ammo. He said he dose not care much for Win ammo and mainly stick with Hornady ammo . He did say he did not get any notice about the ammo that was in the video. But who knows

    I would rather shoot junk commie ammo before I would ever shoot Hornady. Hornady is some of the worst ammo produced. BUT, their bullets are GTG. They just can't load ammo.

    I went to the range today! I shot three cast loads and four Jacketed loads.

    Cast;

    200g RN GC sized 356 BHN 15. Powder coated on top of 18g 4227. Shot 2.5” @ 100.

    190 WFN GC sized .356 BHN 13, also powder coated. Shot on top of 1680 powder. Shot mostly touching 50Y

    180 Ranch Dog GC sized .356 BNH 18 but not fully hardened. Shot ALL ONE HOLE 50 and 1” @ 100.

    Jacketed;

    180 XTP sized .356 24g 1680 shot one hole @ 50 and under 1” @ 100y

    180 Rem HP sized .356 H110. Shot 3” @ 50 never shot @ 100.

    180 Sierra Silhouette SP IMR 4227 21g shot one ragged hole @ 50 and 1.5” @ 100y.

    140FTX sized .356. Seated on top of 21.8g of factory powder. Shot single hole 100y groups!!!!!! VERY IMPRESSED!!

    I have four more boxes of factory Im gonna pull, trim and seat resized FTX on top of 21.8g of factory powder.

    Like previous Rugers this one is shooting better every range trip. No chrony today. Loads derived from Maxi Data and personal experience. Not a single Load shows any pressure signs measuring case head expansion. Used a mix of Mag and std SR primers.

    Maybe you like the European ammo because its usually hotter than US ammo

    Very interesting, but...HOW would the cartridge do in a plain vanilla lever action rifle, perhaps with 16-18" barrel, with a ~160 gr. LNFP boolit a'la Veral's creations? Or, would a heavier boolit be advisable? Could a .357 rifle Magnum be rechambered for this round, and would it be "mo' bettah" than say a rechamber to .357 Maximum? If so, HOW?
    BTW, the video looks like a rifle problem to me.
    IT IS A FINE AND PLEASANT MADNESS !

    This same guy has posted a second video.

    https://youtu.be/8wEvKrgxfvs

    Ammo apears to have been his issue as he stated. He says he has a few barrels and has a friend with another that all have shown same issue. All are fine now with the new ammo Winchester has sent him.

    The bullet weight is 265 grains.

    I am loading the 350 Legend. Had waited till Hodgdon brought out loading data online. They are only showing three bullets, both are .355" dia. For dies I am using 357 mag dies, only sizing about 1/2" down. I am using the 147gr JHP load and it is doing great. From what I read the barrel is .355 but they are giving it extra room somehow to allow loading a .357 dia bullet or even the .358". I may try the 158gr jhp pistol bullet like I shoot in the .357 Maximum, but have not seen any reliable loading data to support it yet. I have used some with .357 maximum loading data and they shot fine, just not strong load. Last, I found the factory cases to vary widely in length. They are measuring from 1.693" to 1.707". Trim length is 1.70". What do you do with that? Using the Ruger Bolt gun. Wallacem in Ga

    PS: Just remembered to mention, I am having a real problem with feeding from the mag to chamber with my reloads. Wont work good at all if I work bolt slowly. Slam it hard and it goes right in. Think it is because of bullet shape. All factory loads feed great. Wondering if that is why factory is using those long pointed shape bullets. Wallace

    Wallacem,

    Look for a try Hornady 158 XTP FP. You can lube them with Imperial and run them thru a 356 or 355 LEE push thru sizer quick and easy!! Im shooting the 140 FTX sized down to 356 for targets and coyotes. (Shot nuttin yet) Im not so confident in the bullet holdin together at 2300 fps... BUT it shoots MOA in my RARR!

    Thanks, good idea on sizing down a tad. Notice my additions about feeding above.
