    Case sizing with mandrel - seating issues

    You always get springback, unless your brass is dead soft, and that's something no one wants. How much springback you get will depend on the hardness of each piece of brass (the more you fire and size the cases without annealing, the harder the brass becomes). I trim and chamfer after every...

    Case sizing with mandrel - seating issues

    Just wait till you're my age, 78, and see what happens. It's an exponential curve. :eek:;)

    Case sizing with mandrel - seating issues

    I take it you're wet tumbling without SS pins? Whether wet tumbling with or without SSP, the cases beat on each other where the case mouths are very susceptible to peening where the edge of the mouth is bent inwards and can result with the ID reduced when the there's been no chamfering. Even...

    Lapua 7PRCW turned brass develops dounuts?

    When I read your OP, my first thought was . . . "sizing with a bushing die???". Even though your bushing is "locked down", you're still going to get a small portion of the neck that isn't going to be sized. And after first turning with the IDOD, I don't think it's a good idea to cut away that...

    Massive runout on factory Berger 230 gr Hybrid OTM Tactical bullets

    Ohhhh. Well, that makes a lot more sense. I've found that kind of issue with any of the "Match Grade" factory ammo I've fired. As I like to experiment to find where I might make improvement with this or that, I taken half a box of such factory ammo, carefully pulled the bullets, weighed the...

    Bad SD and ES but good group...

    I wouldn't focus on any of them until I ran a second ladder tests of the same charges to see which might actually be repeatable.

    Bad SD and ES but good group...

    ??? Seem to me your reloading procedure is pretty good to me to get those numbers you've shown in the OP.

    Flame Anneraler

    Any of the flame annealers can work just fine as they're all simple machines tending to be pretty reliable. It's all a matter of getting the necks heated up to the right temperature for the right amount of time. I've been using my Annealeez for a little over 8 years now having annealed ~15,000...

    Massive runout on factory Berger 230 gr Hybrid OTM Tactical bullets

    Are you there's an issue with the bullet's concentricity or how they sit into the case necks . . . or both? I'd suspect that there's a combination of things that produces that kind of extreme runout (e.g. neck wall thickness variance, a lot of neck tension, seater pin not square on the bullet's...

    Bad SD and ES but good group...

    First off . . . none of those SD's or ES's are "bad". Some better than others, BUT. . . .it just too small a sample size to draw any conclusions. When you first shoot a ladder like you did and see which are the best numbers, you've got to shoot that ladder again, or shoot the one load at least...

    Ring on brass (not case head separation)

    As an after thought, I get a little burnishing ring in that location when I trim my cases with a Giraud 3 way trimmer. A slight vibration from the trimmer cause some contact with the case at the mouth of the trimmer.

    Ring on brass (not case head separation)

    You're at a bit of a handicap, not knowing how many times they've been fired or whether they've been annealed or not (probably not if necks have been cracking). I wouldn't use them unless I annealed them properly first, else you're probably going to see a lot more cracked necks. As for those...

    Maximizing accuracy

    First. . . note a difference between "accuracy" and "precision": I would say that a full or nearly full load tends to be more consistent than low fill loads (having to do with how the powder ignites uniformly as the powder lays in cartridge at the time of ignition. In a low fill case, the...

    Dirty brass

    With pretty dirty brass, hot water and Dawn works really well without even tumbling. Try putting some of those dirty cases into a small bucket of really hot water with some Dawn and even add a little Lemi Shine and leave it sit for 15 minutes or so, then give it a little stir and let it sit for...

    Remington 9 1/2 standard vs magnum

    The standard 9 1/2's work just fine in those calibers. . . even for those hybrids. I use non-magnum primers in all my LRP cases and they work great, including my 6.5 PRC. I do use SRP magnum's in those calibers with the SRP cases . Remington's standard 9 1/2's are hotter than others like...

    These seem to do pretty well:

    Perhaps so for one shot hunting rounds??? 🤷‍♂️

    Nas3 308 Brass

    Is there a 6.5 Creedmoor equivalent my Google Fu hasn't found? Google seems to think I am looking for Berger 140gr Hybrid match ammo. Not reloadable might have something to do with their "wave" design for the bottle neck cases that's reported designed this way to reduce bolt thrust. That wave...

    6.5 PRC loading with 140 ELD

    I find H4831sc works real well for me, but N565 really works the best For 53.9 grs of H4831 you might expect ~2840 fps, for 57.9 grs of N565 . . . about the same velocity. These are warm loads, so if you think of using them or anyone else's, start low and work up to be sure you don't run...

    Nas3 308 Brass

    Similarly, my Sig 277 Hybrid case's volumes measured at 57 grs H2O. I'd received 4 different case headstamps of them and each was a little different. After necking them up from .277 to .308 and firing them, two of the headstamps measured at 57.7, which interestingly is exactly what my...
