    Hornady cases are very good. I use them when I can. I never had one burst but when I was young in my late teens I had a DWM .30 Mauser case yield and explode out from the receded rim of the case. The reason it blew was because of a balloon head case and mercuric primer contamination via the primer evaporating through time into the wall of the cartridge case. I took the case to my biology class microscope and I saw the silver color of the mercury embedded in the edge of the failure in the case. It was amazing how much metallic mercury was seen mixed in the brass. I never had a modern case rupture or explode.

    I've also noticed that not only does case taper influence thrustback on the boltface.... but also amount of case body length can influence the thrustback. The more case length, the more surface area that there is to help grip the chamber and reduced thrust back on the boldface.
    So together, a minimum case taper, with longer case wall surface area.... along with a clean chamber....all three influence case/bolt thrustback, when all else is equal (pressure).
    As Ackley put it.... better gripping of the case in the chamber... influences bolt thrustback.
    I've had blown case heads (separations) with a combo of pressure too high, in a "springy" action.
    British NO. 4 action is horrible with case head separations along with the Savage 99.... both rear locking actions with a surprising amount of "spring"!
    I've had a few in Marlin Lever Actions using short straight walled 44 magnum cased ammo, along with their rear locking actions.
    For me, all were controllable by keeping the chamber pressures "reasonable"!

    Fatigue cycling. I love it! I did so many papers in college on this. To see it on real life makes me giddy. Bc of the advancements in cnc machines, we can reduce the case stretch by making chambers and brass a tighter fit. (Match grade brass and chambers like 6.5cm 7prc)
    Those steps are noticeable, you get increased accuracy and increased gun life w/o a hand fitted and lapped gun. All from off the shelf parts

    On the annealing side of things, I've got Lapua brand brass for both a 6.5 creedmoor and 338 Lapua. It work hardens so badly from firing that I've broken several expander/depriming studs. So, I've come to the conclusion that annealing is necessary with Lapua brass.

  • @jamiecarter9357
    @jamiecarter9357 Год назад +1

    Years ago I ordered a 35 lb box of once fired 5.56 Lake City cases and processed about 2000 of them to make 223 loads using Hornady 60 gr V-max, and the rest to make 300 blackout brass before it was easy to get. I swear the boxes were labeled V-Vax, but that's another story. I sized each case, then trimmed them to length and then uniformed all of the primer pockets and deburred them on both ends, including the inside of the flash hole. Only after making the exterior dimensions the "same", I sorted them by weight. Right around 93 grains, I think... it's been a while. Loaded with 25 grains of Varget or the same amount of H4895, the accuracy was stupid crazy. I also crimped the cases very lightly using the Lee factory crimp die. Like phenomonal. Benchrest accurate all day long and yes, I've fired thousands of them. As a result, I've used the Lee crimp die on every rifle cartridge I've loaded ever since. Gotta get crimp dies, Hornady... just saying. Anyway, loading the same brass with no processing at all still gave excellent accuracy. Like still hitting eggs at 300 yards almost every time in good conditions. I only trim to length now if the case it too long.

    In addition to making sure your cases are clean and dry, it is equally important to make sure your chamber is also. I keep a pistol length cleaning rod with a chamber swab on it. I’ll use acetone to lightly soak it and swab the chambers of my rifles prior to a shooting session.

  • @kibbeystovall7546
    @kibbeystovall7546 Год назад +1

    Around 4:20 Seth describes "dumping primers" during a rainy shooting match. I assume he means the primers are being pushed out of the cases, but I don't see how water lubricating the cases would have that effect. Can someone explain, please?

    • @edhouse4826
      @edhouse4826 Год назад

      So when he discusses the leaving lube on cases and the pressure on bolt face being double or more, that means too much pressure is going backwards. Wet cartridges are basically lubed. So extra back pressure which pushes out primers.

    • @milesn3173
      @milesn3173 Год назад +2

      Wet chambers/ammo causing the case to swell and drop primers isn't so much about lubrication as it is that water is not compressible. If water [partially] fills the void between case and chamber, it causes pressure to spike which damages the case. Imagine sucking water into your car's engine instead of air/fuel gas. Pushing trapped water is hard on things. More air gap between the chamber and case will cause pressure to drop. Obviously too much air gap will cause ruptures.

    • @milesn3173
      @milesn3173 Год назад +1

      @@georgejohnsmith No. If you make a cartridge/chamber fit exactly 1:1 with no radial air gap, regardless if that's done with incompressible case material or incompressible water, it spikes internal pressure. You need a couple thousandths of an inch clearance for things to work properly, especially in the neck. Increased bolt thrust from lubrication does not manifest itself in loose primer pockets (radial expansion). Excessive pressure from inside the case does. Thick necks that are a 1:1 fit into a tight chamber will show this immediately with what should be "standard" loads wrecking primer pockets and dropping primers.
      Lightly lubricated cases, that only have a film of lubricant on them will cause higher bolt face load, but that doesn't manifest itself in radial expansion of the primer pocket. Lightly lubricated cases will in fact help brass life (less "grabbing" the chamber and stretching) at the expense of bolt load. Excessively lubricated cases (where oil/water/whatever fills the void between case and chamber) will spike pressure and wreck cases as well as provide extra bolt thrust.

    • @kibbeystovall7546
      @kibbeystovall7546 Год назад

      Thanks for the better explanation of how you imagined water affecting primer push back. You are correct that liquid water is essentially incompressible and if that prevents the case mouth from opening and letting the bullet go early in the pressure rise (as is supposed to happen) then you can get higher peak pressures because the gunpowder has less volume to expand into (at least initially). I suspect the small intended gap between the neck and chamber would tend to wick water fully into that gap before firing if a drop was on the bullet or neck when inserted. The minimal loss of volume available for the powder to burn because the chamber is tight (either mechanically or because there is a liquid in the gap between the case and chamber) would only be a very minor contributor to chamber peak pressure (I think Siewert makes this same point elsewhere in this video). A higher peak pressure should, again all else being equal, increase the tendency to push the primer out.
      Best explanation so far.

  • @williamdecormier7894

    @randomidiot8142 8 месяцев назад

    11:00 Tubb and the elr guys tend to leave a little lube on their brass. Talking about case failure and having the brass stick to the chamber.. have you heard of case head separation? 14:18 you hear the guy say lube increases bolt load and somehow that translates to increased pressure.. two different things. 23:40 if you got a barrel that actually gripped a case you'd have it rma'd. 31:12 the belt on the win mag doesn't make it stretch. When you make your brass super short to guarantee clearance in the chamber, you have issues. When you take the belt away you have to make it right, or at least better, or it won't work. 37:30 no one reloads tank shells. The .303/.300 win mag issues encountered in reloading are a non issue. Reliability in the field was all that mattered and the .303 and .375h/h did their job. 40:04 I did a pistol seating depth test and it wasn't until I was .100" deeper that I saw any changes. Somehow, deep seating rifle bullets makes pressure go down but it makes pistol pressure go up. 41:20 I think I did that with a .50 cal. Long lead bullets and fast powder in a straightwall case, lots of bullet shearing at the end of the chamber. Had to redesign the reamer.

    So they sell Arbor presses where you can see the PSI used to seat the bullet. This is directly correlated to annealing and neck bushing size and/or expander mandrel. Neck thickness matters depending on methods used. Generally I know if it takes more than 40psi to seat my bullet, my brass wasn't annealed long enough.

    1:03:00 multiple people have shown the same results in multiple cartridges, guns, shooters and ammo types(factory and hand loads) that run out doesn't matter in 99.999% of practical shooting. Possibly at the bleeding edge of long range bench rest international championships wins and losses or maybe ELR/ULR, but that data is still inconclusive on whether or not it matters in those applications.

      @jeffsiewert1258 Год назад

      IMO, a steady diet of polymer cased ammo isn’t desirable unless your gun is specifically designed to use the plastic cased ammo. The peak bolt load is crowding double what you’ll see with brass cases.

      I just checked that.. The answer is: almost but not quite. If you scale the 30-06 case up to the same dimensions as 50 cal case (at the aft end of the body taper) the 50 cal case is shorter and the shoulder is short of the 30-06 shoulder dimension.

    @BitsOfEternity 6 месяцев назад

    In the older video you posted, where Joyce goes through the process, he talks about neck sizing, and full length sizing, and he mentions that if you're firing the same brass in the same rifle, neck sizing is the way to go, because after firing the case has expanded to fit your rifle, and shouldn't need to be re-sized. Are we saying here that that was false? In his explanation, he said that the case OD expands until it touches the walls of the chamber, but there's nothing in the explanation where the length changes. The length changes if you resize the length, but if you fire it once, and it fits your chamber, it seems to me like neck sizing only would be the way to go, if it doesn't affect group sizes, and helps the brass last longer. Seth even said that's what is done at Hornady, just neck sizing, and since Hornady is concerned with accuracy, I would have to infer that there's no appreciable difference to re-sizing the full length. That being said, he had a case get stuck, which is why he then went to full length resizing, but he didn't mention if that one that got stuck was one he had never re-sized in the first place, but maybe hadn't fired from his rifle prior to reloading that round?

    Since you’re talking cartridge cases, can you make a sequel discussing why Hornady cases develop loose primer pockets faster than just about anyone else? Surprising since everything else Hornady makes is of top quality.

    Bolt face pressure..... is this a concern for bolt, semi, or both actions?

    On your take of annealing, in my experience sizing and neck tension is much easier and consistent.

    I tried neck turning once. It WAS more accurate.
    Neck sizing never gave my better accuracy. I agree neck sizing does only saves brass life.
    What seems to contribute most is whatever will guarantee the most consistent bullet alignment to the bores' center.

    So what IS the difference between radial and hoop stffness?

    • @jeffsiewert1258
      @jeffsiewert1258 Год назад

      Radial strain is from the inside surface to the outside surface perpendicular to the longitudinal axis of the case. Hoop strain is around the circumference of the case. Hope that helps.

    Speaking of runout. When the brass is shot its concentricity is pretty good. But after sizing it introduces more runout. Not that I gauge it as to significant. But MY question is what causes this. Is it the dies? I have 3 presses and they all have the same result. So thats probably not it.

    • @jeffsiewert1258
      @jeffsiewert1258 Год назад

      The increased runout after resizing probably comes from the clearance between the threads of the die and the press.

    Unsupported case head expands under excess pressure... the Primer pocket expands too much, so that it is too large to hold a Primer in the pocket.
    I had an accident with a 6mm where the case head expanded .01" ! The brass looked like a belted magnum case!
    I had to pound that Remington 788 bolt open. The Primer fell out.
    I hit the groundhog too!
    I learned a valuable lesson that day.
    A ball powder max load that was loaded and tested on a 75 degree day.... but shot the groundhog on a 95 degree day.
    Temperature difference with that ball powder loaded too hot!
    Keep loads below max!

    Sometimes it's what YOU feel is the best, makes it the best ammo. Even if the scale shows variations in powder or case weight or the the chronograph shows large velocity variations..... if you are convinced that your ammos' the best.... with YOU shooting it, it shoots the best. The psychology makes it all shoot the best.

    Yea we don’t polish chambers to a mirror finish for grip. Especially on autos. Especially especially if it’s guaranteed going to shoot steel cased.

    He has worked on some interesting tests for the gov't, and has seen some of the fun stuff they've done. Reminiscent of some of the stuff from Col Hatcher in his note book, and I'm betting some of that really hasn't changed much. A guy like Ken Oehler cpuld tell a few stories, he'd be another good one to have on, he's had exposure to some of the stranger aspects of ammo work as well.

    Use cartridge cases with small rifle primers because I can buy them. I haven't seen large rifle primers on sale for over 3 years.

    I have a BS in physics and mathematics and suspected there was more to ballistics and firearms than I initially thought. Some thoughts on spin pressure of center I never knew. I'm starting to understand twist and stability. A very complex study. Wow
