    What, praytell, happens if you accidentally double charge a round? Has this happened to anyone? I can't help but wonder.

    I'm loading .44 mag with my Ruger Redhawk, and I'm being very careful. If I did double charge and a case ruptured (say a double charge of Titegroup) I'm imagining the Redhawk PROBABLY wouldn't just explode, right?

    I have had TWO Kabooms in .40 SW. Glock 27 and Beretta 96 and both were plenty violent just from case failures! Double charge will DESTROY a firearm as well as injuring the shooter in Most cases. Gunzone has some good pics of destroyed guns from KB. If there is any chance of a double charged reload, weigh them for consistency as a Revolver would literally be a FRAG Grenade in your hand.

    I double charged a .44 Rem Mag. with 6.8 x 2 of unique under a 200 grain cast bullet. Only problem was the noise, recoil and primer pocket.
    Did get my attention while shooting a 4 inch m-29. Were still fine.

    At my last steel shoot, this guys Kimber just went Kaboom. His mag was destroyed and it blew the grips off. His face was all bloody but he was ok. I felt really bad for the guy.. He also messed up his gun, we couldnt even move the slide any more.

    While shooting in a PPC match at the Los Angeles County Sheriff's Range in the late 70's, the guy shooting next to me at the 50 yard line had his very nice S&W Model 19, with Bomar Rib, go to pieces from either a double charge of Bullseye, or a triple charge. The top three chambers of the cylinder were torn out. The backstrap was completely gone and the Bomar rib, when it finally landed, looked like a horseshoe. Fortunately, he wasn't hurt, other than a stinging hand and his hurt pride.

    Small amounts of fast powder are easy to double or triple, if you don't watch closely.

    Hope this helps.

    As a general observation without actual experience...

    Rugers may live through a double charge. S&W's seems more likely to grenade.

    The faster the powder, the more likely to run into a problem. due to the volume of the charge and the speed of the pressure rise.

    Lots of times newbies want to use lighter charges of faster powder (economics I suppose) and they're the ones that should use the slowest powder.

    Had what I'm sure was a double charge of Bullseye in my Colt Gold Cup in 45 ACP. I got lucky and all it did was blow out the bottom of that magazine and the web of that case...kept it as a reminder to pay better attention.

    I have seen a few double charges over the years, 1911’s get cracked grips blown out mags and destroyed barrels for the most part. I have to say the one that surprised me was a glock 34; it just blew out the base of the case and locked up. After getting the case cleared and checking everything out the pistol went on and finished the match. I have seen many squibs and some shooters that have tried to rack another round in the chamber, before stopped. I think that would be worse than a double charge.

    My son blew up his 45 XD (and pissed off Dean Spier at the same time, long story).

    He and I must have double charged a round (we were using 4.5 or 5 grains of red dot, can't remember the starting load we were using) on a single stage press that we were using. Now that I look back, I can see what we did wrong.

    We were trying to be more efficient than you should with a single stage.

    What we were doing was resizing the shells, then priming them in our Lee autoprime. Then we trimmed them (before we learned that you really don't need to trim 45 brass everytime) and then belled them.

    Next we grabbed a shell from our loading block, charged it in the Lee powder charger and grabbed a bullet and put it on the shell and put it back in the loading block.

    So what we were doing was trying to save a step inbetween charging and putting the bullet on top of the charged round but that meant that we didn't get the chance to use a flashlight and peer into the charges to make sure that they are all evenly distributed evenly.

    Needless to say, that I think was how we over charged the round.

    We went shooting and I heard an odd boom/snap from the lane over and mykid walks over saying he blew up his gun.

    He was pissed as I was after we realized that he was okay except for a bruise and some stinging.

    We took it home, disassembled the weapon and removed the shell. The only visible sign of damage was the crack on the right side of the frame. We put the gun back together and it dry cycled perfectly. We of course never shot it again but then shipped it back to Springfield.

    They replaced the frame (reasonably too) and thats all that was needed. The slide and the barrel were still in perfect condition.

    Yeah, it sucked as a learning lesson but its a lesson well learned and now we are much more careful. We also were very pleased with just how well the gun held up to an apparent double charge. I wonder what would have happened if it was a glock?

    I saw a Smith .357 stainless snubby kaboom at an outdoor range. I don't know what he was shooting, but I'm guessing a double charged reload.

    The cylinder blew apart into 3 pieces. One piece, about half of the cylinder, blew 60 feet to the left. Another 1/3 of the cylinder went 40 feet to the right. I believe either piece could've easily killed someone if it had hit them. The third cylinder piece wasn't found. The top strap was totally blown off and wasn't found either. The person shooting it wasn't hurt.

    I think of that snubby each time I sit down at the reloading bench.

    True dat!
    I am only a novice reloader and I try to use less powerful powders for the weight for just that reason. It is kinda hard to double check by weighing the finished cartridges when the weight variation between cast bullets and different manufacture cases can be close to the the same difference of a double load versus a single load.

    Never a truer statement!

    The very fast pistol powders are the ones most likely to get you in big trouble fast!

    Saving a few cents a box on powder is not a good enough reason to use them when you are just learning to reload.

    Only with a 12 gauge double barrel, years ago, where some newbie fool (me) had his fingers on BOTH triggers. I learned fast.
    Talk about recoil. :eek:

    What is a good suggestion for a good overall slow burning powder for plinking loads for 9/357mag/40/45? I know thats a long shot but something that might be useful next time I go to buy powder.

    Fill 'er up with unique is an old timer's saying for the reason it's hard to overcharge with a powder that pretty much fills the case. I happen to like Unique and Herco for 45acp. They are both somewhat bulky. 5.0gr of Unique fills 9mm case almost to capacity, and it meters well. I'll let someone else make a recommendation for 357 and 40, but there are loads for Unique in those calibers, and I would think a double charge would be obvious.

    Do you mean accidently, or on purpose? :rolleyes:

    Herco. But a bulky faster powder (like Red Dot or Green Dot) is better for 9mm plinking loads.

    Did it last week. Double charge of win231 in .45acp in a XD45C. Blew the baseplate of the mag down (mag still in gun), and cracked the frame in 3 places. Cut my thumb on on the web. I should have got stitches but didn't.

    ETA...dad did it in his G21. Blew the barrel into 4 parts, blew mag out, blew a exit hole in the side of the frame. Broken finger, 8 stitches, and still has plastic in his finger (this happened 10 years ago).

    CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The High Road, nor the staff of THR assume any liability for any damage or injury resulting from use of this information.

    1) I have done double loads and got away with it in strong guns in cartridges what have wimpy max average pressures registered with SAAMI. Many of those were almost triple loads:
    25acp
    32 acp
    32 S&W
    380
    38 S&W
    38 Special
    9mm Luger
    40 S&W
    45 Colt [in a .410]
    454 Cassul [in a .410]

    2) There are cartridges I have worked up to a real limit, but never reached the double load in a work up:
    10mm
    357 mag
    45acp
    223
    243
    30-06
    8mm
    308
    7.62x54R
    270
    257 Roberts Ackley
    45/70

    3) I know that I have worked up 7.62x25mm to the limit, but I am not sure if I have reached double any max published loads.

    That's one reason I like AA#9 with the 10mm. You throw a double charge and it'll overflow the case. I'd much rather deal with cleaning up that fine ball powder than have to deal with a blown-up gun and the concomitant injuries. :D Just for grins, can anyone weigh in on how .45ACP and how any other powders fill up its case?

    You might consider loading down to .45LC type pressures. I used to load my Ruger up to real stomper levels, then figured out that you can only kill paper about so dead. It's also way more fun to shoot than getting the snot kicked out of you with every shot. My 255 LSWC will poke clean thru a deer from any angle. About anybody that shoots it does very well.

    What else do you need?

    Unique for Safety

    I agree with the Unique recommendation, in 40 S&W, which is what I load, 6 grains of Unique behind a 165 grain Rainier fills up the case 2/3rds full, a double charge would overflow the case. This is why I like Unique, its bulky for a given charge weight, but offers excellent performance to boot.

    Same thing for 357 mag, 9 grains of Unique fills the case 2/3rds and its an awesome load. Once again, a double charge would overflow the case. I would say its pretty much impossible to double charge Unique in 9mm, 357 mag, 40 S&W, 45 ACP. 38 special is a completely different ballgame, 5.5 grains of Unique only fills the case about 1/4 full, gotta be carefull with that one.

    I can say that I have loaded 10,000 rounds of 40 S&W, 38 special, and 357 mag, combined, without a Kaboom.:D:neener:

    Hell Yeah

    Stupid Me, I Was Loading 10 Mm For My Glock 20. I'll Admit, At The Time, I Was Seriousy Distracted And Had A Serious Argument With My Girlfriend. Anyway, I Created A Squib Load And Then A Double Charge.
    I Was At The Range Firing Off. The Squi Load Made A Poof Sound And Then, Stupid Me, Instead Of Putting The Gun Down, I Pulled The Trigger Again Kaaabbbbbboooooooooom
    The Barrel Blew Up.
    I Swear, If I Were Using A Cheaply Made Gun, I Would Not Be Here Today To Tell This Story. I Sent The Gun Back To Glock For Repair. They Called Me A Week Later With A Long Lecture About The Dangers Of Reloading. I Had To Purchase A New Pistol.
