Need to eliminate unburnt powder in my Uberti saa

    I started a thread in the revolver forum about this, but it’s turning into a reloading thread and I’m not getting very many responses. So, I’ll try here.

    The problem is that only on the first round of each group of 5 shots, I get a small spray of powder in my face. When I look in the cylinder, there is tan colored unburned powder specs. I have eliminated oil as the problem because the gun is fairly dry at this point. I’m using acc. #5. I’m wondering if a fast powder will prevent unburned powder. I can get some titegroup, as it’s available and fast. Do you think all the powder will burn?

    The confusing thing to me is the fact that it only happens on the first round. All of the chambers have some unburned powder, but the first shot is when I feel it.

    What powder? I had issues with blue dot not burning well in 10mm. Magnum primer solved it.

    He says Accurate #5.

    Ahh yes thanks. Over looked that. I have no experience with #5.

    Unburned powder indicates that Acc #5 is too slow for your use. You do not say what caliber and bullet you load for, but Hodgdon lists Titegroup for everything from 25 ACP to 500 S&W Magnum.

    Try a heavier crimp first, and possibly a magnum primer.

    What Weight are the Bullets you are loading?

    What gun, what load? More info would help.

    But, imo, unburnt powder is an indication of low pressure. You implied it's a revolver, so I would suggest increasing the crimp, using a roll crimp if you're using a taper crimp on a light load (38spcl, etc...) or bumping the charge a bit.

    Two easy solutions. 1. Use a faster powder as you stated or 2. Run a higher pressure load. Every powder has a pressure where it reaches complete burn. This happy place is not documented and is different in each cartridge. A third possible solution is to run a hotter primer. When using something like 4227 in 357 mag a srp helps.

    I've had the same problem as the OP with Unique back in my early days of reloading (revolver cartridges)

    I almost always got good results in roughly the middle of the data I had but bumping my charge up a 10th of a grain or 3 solved my unburnt powder problem 9 outta 10 times.

    Not sure why I didn’t provide more info. Probably rushing during work :)

    This is a Uberti SAA clone chambered in 45C. Bullets are 250g XTP. Using 11g of acc #5 which is the maximum.
    I have tried increasing crimp. But I ought to try a magnum primer.

    I will tell you, I don't use AA5 shooting suppressed in 9mm and 45 ACP for the very reason you're experiencing....especially from AR type PCC's...the debri injection straight into the eye is unpleasant. I don't see the caliber you're referring too...so I'll <dangerously> assume 45 Colt. I use AA2, Cleanshot, or TG for my 45 Colt cowboy loads. TG is a great powder for those big cases, and it burns pretty clean. If you are loading really light (like under 600 fps with a 200 grain bullet) you might get sooty cases with these powders, nature of the beast.

    Edited to add: I see where you updated load data. Personally, I would not run a steady diet of 11 grains of AA5 under a 250 grain jacketed bullet in an Uberti 45 Colt. Fine for now and then, but not a steady diet. I would back that down for regular shooting. I know that according to the load data, that is the max load for standard colt, but it's right at 14,000, and the Uberti, while a gorgeous gun, is not built to handle a steady diet walking right up on the edge like that. I would switch to a faster powder, and reduce the load off the max at least 10% for that gun, and for everyday plinking and target shooting, I stay in the lower side. That's just me though.

    45c is a comparatively low pressure round like 38 and 45acp. Some powders don't get to their happy pressure even at max loads in some chamberings. I think you would be much happier with herco, unique or universal.

    That is an odd one, that is the max load according to Lyman 50th with that bullet. 10 grains is their accuracy load with that powder. No mention of pressures. Looks like the velocity of that load is respectable too. The primers used are WLP. I would double check OAL 1.590 but it does have a crimp grove. If you have a Magnum primer try the 10 grain accuracy load and see if you get full burn. I am not familiar with that powder and wonder how it fills the case. As you said from your other post it is the first shot so that powder may be position sensitive. Try starting with the gun pointed high and let the powder settle back towards the back of the case. All free checks. Ultimately it may just be a combo that doesn’t work, that happens. Funny though as mentioned 10 grains is the accuracy load, Lyman is usually pretty accurate with such things.

    get some cast & coated bullet with a good crimp groove, give them a solid roll crimp.

    AVOID magnum powders in a Uberti SSA clone.

    ( these are homebrew clear-coated 44 Keith's, but you get the idea )

    PS- win231/HP38, Unique, Universal, and CFE-p powders also work well.

    It happens, even sometimes with my favorite, most accurate loads....
    It happens more with slower Powders like 2400, WIN-296

    WIN-231 never leaves any residue in anything.

    Unless it's excessive, it's not an issue.

    It's an issue when burning powder is flying at your face. And god help me if I forget to put my glasses on...

    I just go by my data choices. Acc.5 is one of the choices for a non-Ruger load.

    With this information, I would suggest a different powder. You've increased the crimp, which didn't help. A magnum primer MAY help, but I would think a different powder would be a better option.

    Some good options have been offered above. I am using W231 for my 45 Colt loads, although I have to admit I've only recently started loading for this caliber. It works for me and I have no unburnt powder using a 250gr lubed lead bullet.

    Did you have this problem during load work up? Or did it only start when you got to the max load? The fact that it happens only on the first round and never again during a shooting session makes me think it might have to do with fouling at the forcing cone.

    I didn’t see Accurate No.5 in your testing. Did I miss it or did you not test it?

    yes, AA5 is another medium speed burning powder, I mistakenly thought you posted "magnum powder", when you typed "magnum primer".

    sorry

    I've never tried AA5 in 45LC, but I'd imagine it would work fine with more roll crimp

    You didn't mention the barrel length... that can make a difference. I'm assuming 5"+, but I know there are some shorties out there.

    I agree with the other poster... if you are already at max load, you need to find a better solution; save your nice pistol. FWIW... I had this problem in 9mm, using BE-86. I reached a threshold where more powder didn't translate to more velocity, not in my shorter barreled Kahr. It was dumping unburnt (underburnt?) powder on my hand, even. It was just the weird combination of bullet/powder/barrel... Unique, which has a similar burn rate (and characteristic..) never did that.

    There is one other facet... the pistol. My experience with Ruger single-actions tells me to check the cylinder throats for uniformity... you may have a big throat that isn't the right size, or the cylinder is not even... leaving a bigger gap at one cylinder position than at it's 6 O'clock.
