    Which wet tumbler?

    in General Reloading

    Posted

    Separating and handling the pins is the biggest pain for me.  So is drying.

    The pistol brass that I wet tumble ends up too clean (if that makes sense).  It sticks to the powder funnel and makes for a rough upstroke when loading on a 550.

    I end up tumbling in walnut (with polish added) anyway. 



    If you ditch the pins it doesn't stick as bad on the powder funnel (because you're not scoring the inside of the cases) and you'll also get rid of what was, for me, the worst part of wet tumbling. Primers seat easier too!

    Just one note - if you have metal dental picks or something similar you can adjust pre-travel without stripping the trigger from the frame.

    Otherwise agree - if the over travel screw works itself in too far you'll have a harder pull.

    Truer words have never been spoken - Unless I'm trying to put 5 shots on top of each other @ 100 yds, 3 hrs in the walnut+polish is more than clean enough.



    I used to use pins, now I wet tumble without unless I'm deburring trimmed rifle brass. Keeps the lead dust from getting all over which is the benefit for me.

    Our 929's one year later

    I agree with ^^^ re: the bit needing to shoot 135+ .357 sized bullets for decent accuracy, making the 929 as a gun that can shoot any 9mm loads a pipe dream.

    No idea what the bit about oversized chambers is about? The nonsense re: titanium's inherent deficiencies is just that. Never had an issue with sticking, galling, etc... But I know not to f*#k with the Ti cylinder as removing the anodizing has a definite negative impact, and the need for chamfering is IMO pretty small if you're using RN bullets since the cases are tapered, minimizing issues with a case hanging up on the case mouth.

    DAA shotmaxx timer

    Thanks alma, since I have private outdoor places to practice I just use my regular timer. I may look into transferring my match videos to my iphone... 



    This is what I do. I save my videos to a OneDrive folder and then use the OneDrive app on my phone to save the videos and run them through shot coach. Making use of a ShotMaxx times from spy mode is more painful than learning the Shot Coach UI. And that's saying something.

    I used to bring a lot of friends to the range, now I try to not bring any body as much as possible so I can selfishly practice.


    Sent from an iDevice. Please forgive any grammatical or spelling errors. If the post doesn't make sense or is not amusing then it is technology's fault and most certainly not operator error.



    I do the same. The only exception is bringing a friend who's going to be running the same drills and practicing with the same mindset.

    I'd like one for local falling steel matches, but I think after one match they'd put in a rule prohibiting them - 2 extra rounds / reload on a 25-30 round string adds up to a lot of time. I'd still buy one at $1500 - $2000

    This would make a big difference on Classifiers with mandatory reloads



    Not sure that it's that much faster with coupled mags. The only coupler I've been able to find for colt mags required that they face different directions which kills quick changes. Even with a standard coupler, I bet I could reload just as fast to a 10 round colt / standard 17 Rd Glock 17 mag off the belt.

    this is changing the rules, not just an interpretation.



    How so? Do you know something DNROI doesn't?

    Autocomp 9mm Major Load Data

    Too what end though? For minor the heavy bullets equal low charge wgt of powder and less recoil muzzle lift.

    With major comp guns we want fast cycling, high gas volume loads to make comp work most effectively.

    Seems like it's obvious that these are two completely different processes.

    I'm not sure if I didn't communicate clearly in my last post. If I used the same powder for two different weight bullets, then sure the heavy bullet = lower charge = less gas for the comp. But thats not what I wrote. My example was using two different powders so the same charge weight led to the same PF for each bullet. Then you would have the same amount of gas working the comp got each round.

    Now there might not be an powder where you can use the same charge weight as you do with HS-6 and 115s for 147s, but a lot of folks seem comfortable with a middle ground of 124s and low 7 grains of powder. You can make the same PF with 147s and low 7 grains of 3N38.

    Peter,

    I've tested 9mm and 38 super loads in a handful of pistols with different comps, barrel lengths, numbers/sizes of holes, bullet weights from 95gr to 135, and the following powders:

    Power Pistol, WAC, CFE Pistol, Silhouette, Longshot, HS6, 3N38, SP2, N105, and Lil Gun.

    WAC and 3N38 have very different burn characteristics, so 7gr of one gives very different results than 7gr of the other.  Your test would give you valuable first hand data, so I suggest you do it, but I have a pretty good idea what you'll find.

    There's a large degree of personal preference in load development, and each shooter has different priorities with regards to soft vs flat, noise, flash, and peer pressure, so there is no substitute for rounds down range.



    I'm agree with your comments re: the burn characteristics, but really only think there's one part of it that matters. Running a Sim in QL, both rounds reach a similar max pressure within .02 milliseconds of each other (.00002 seconds). Both generate the same volume of gas. Where they differ is the pressure that gas is under when the bullet hits the comp and the gas starts to work, with WAC at 200 PSI and 3N38 at just over half that.

    So the WAC would work the comp more efficiently. The pure recoil impulse will be indistinguishable as the momentum of the projectile and ejecta is nearly identical between loads. However, the WAC load will feel harsher and more violent due to the additional noise / pressure associated with higher pressures at the muzzle.

    At the end of the day the 147 loads are more expensive and likely don't perform quite as well unless your hearing is still fully intact and the extra noise from the 124s make them uncomfortable to shoot, but I doubt I'd see any difference on the timer.

    Am I close?

    That was a solid vid. Here's a question / observation.

    Gas volume is based largely on charge weight. So if I use 7.2 GR of WAC behind a 124 or 7.0 GR of 3N38 behind a 147 I'm getting similar gas volume, so if I'm getting the same PF recoil should be almost indistinguishable.

    Now, one of those combinations may be more expensive, but I'm not sure it would be objectively worse in a blind taste test.

    Troy's answer contradicts the rules, it's pretty clear they aren't allowed per the rules.

    Is this a change to the rules or does DNROI have the ability to change rules by answering a question?



    There is no change in the rules. DNROI has the authority to interpret the rules. So it's really a non-issue.

    Fastest powder with lowest charge weight?

    in 9mm/38 Caliber

    Posted

    I'm talking about 9 minor, as I've been all along. Don't start reaching with including 40.

    Do you comprehend at all?

    You have Nitro and a 124. Let's pretend 2.2 is max. You load  (hypothetically) 2.0 grains. It goes 850 fps. You load 2.2 it goes 900. You load 2.6 it goes 975. You load 2.8 it goes PF. 

    2.2 is hypothetical book max. It took 2.8 to make PF. Therefore, you can't load Nitro and make PF without 1. Going over max, and 2. Probably hitting a massive pressure spike with that type of powder. 

    I don't care about the heavy bullet combo, or 40. I not talking about either one. My point is, THE PURE CHARGE WEIGHT of the "fastest" powder can't be used to make PF within spec, WITH A 115/124. 



    That is very different than this;

    You will significantly exceed max pressure using fast powder and 124s. You will no doubt go +p+ before you even reach PF.



    Also, if you're qualifying # 2 in your list with a "probably" you shouldn't include it, since it's just a guess. You may as well say "it probably won't accurate", "it probably will be snappy", or any more of the many "probably"s one could throw in.

    To say nothing of the fact that the book max reflects the projectile used in the book, loaded to the OAL in the book (that's a pretty important one), in the books factory test setup. Loading long is one way to reduce pressures for a given load with minor impact on velocity, and something experienced loaders take into account.

    When you paint with a broad brush, as you did in your very first post here, you're going to be wrong.

    Lol.

    I've listed over and over, ramcomp, TW, nitro, ect. That's what data I gave in my other post... RAMCOMP. And that was in reply to someone mentioning 310. So you may need to find some clarity, not I. I clearly know you can't make a load using the aforementioned powders, a 115/124, and be within specs pressures. 

    Edit: matter of fact, go re-read the thread title... "fastest powder w lowest charge weight"... might as well recommend some R1 for the guy since allegedly you can make safe pressures with light weight bullets. Lol



    Here's another gem of yours:

    310 is up there with ramcomp, tite wad, nitro 100, etc. Those are best used with heavy bullets, as the charge weights are low.


    Again, your inexperience is showing. A low charge weight doesn't mean a lower peak pressure is reached, or the combo is any safer. In fact, just about any reloader would agree that fast powders with heavy bullets are a much more volatile combination than fast powders with light bullets. But here you are letting us know that making major in 40 with Clays and 200 GR bullets is OK because lower charge weights are used, but making minor with RS Comp and 124s is not.

    I think I've made my point here.
