if this is posted in the wrong please move it , didn't see another header to ask this question



not to pick on any one gun but every time you turn around a certain gun has a report of a ka-boom,

I HAVE PIC OF AL KINDS BUT 1 SEEMS TO BE THE TOP KA - BOOMER

could this be from reloads and the slight bulge in the case falling in the right spot at the wrong time, do to the round not being fully supported?

my question is has anyone have or heard of any ka-booms from the XD LINE YET?
 
If you search long enough, you can find kaboom reports on just about anything that goes bang. The problem is that only occasionally is there a definitive reason given for it.
The cause for any given gun coming unwrapped could easily be an idiot reloader or a bad factory cartridge...and that usually is the reason. Very few reloaders are willing to admit that they blew up a gun through their own carelessness.
 
factory reloads are what got me into reloading, had a ka-boom in a SF1911-A1 :barf:

only damage was to my hand and the mag :eek:, it felt like i just pulled the trigger on my 44 mag :what:, lucky only round was left in the mag, round in question blew out the rim and set off the round in the mag then it all came out the bottom, still have a bag of stuff we found after the hurt stopped.

figured i could do better and so far no more ka-booms. but 3 close calls,
if it had been a revolver story would be different, had my pro 1000 skip a charge in a 9mm and a 45 acp. i caught one of the 45 and the 9mm had enough power from the primer to stick an inch into the barrel.

i don't use the lee powder measure any longer still do not know how it skipped a charge as each pull something happens, just by chance caught the 45 it was on one i stopped to check with the scale to make sure all was still what it was set at. last 2 things i do by hand now , powder and seat the bullet

also carry a small rod with me to the range now too , i have not needed it but i have had other shooters need it to knock a squib back out.
 
It's simple really. If every type of gun can and will suffer a Kb, then the guns that are the most popular (meaning most produced and sold) will have more Kbs in terms of absolute numbers.

Example:

Given - Kbs happen at a frequency of, say, 2%.
Springfield sold 100 xDs in .40S&W
Glock sold 1000 G22s

Springfield will have 2 Kbs and Glock will have 20.
 
Met a cop at my old job at the gun shop and he showed me a picture of his xd 40 that blew up while he was qualifying with it. He said that he believed it was a squib load out of his winchester fmj he was shooting and it blew the side of the frame off rendering the gun inoperable. This is the first instance ive heard of a xd blowing up but again there are a TON more glocks out floating around than xds
 
Any gun will KB if there's a barrel obstruction (such as a squib lodging in the barrel), or if you get an overcharged cartridge.

Glocks have more KB's because they use polygonal rifling which is advantageous w/ jacketed rounds as it forms a tighter seal than cut rifling. The downside is that if you use lead rounds (like cheap range reloads), the bullets are likely to lead the bore. Not a big problem in cut rifling, big problem in polygonal rifling. If the bore gets leaded in a Glock to the point it really slows down the bullet, the bullet will still be in the barrel and the pressures will still be really high as the slide retracts from its engagement from the barrel. As the brass starts to come out of the chamber and the thinner side walls of the brass move past the chamber, the increased pressure blows out the side of the casing, causing a KB. This happens just above the base of the cartridge where the thin brass is first exposed: giving rise to all this "not fully supported case head" myth about Glocks.

Same thing happens to the brass if you get a squib or other barrel obstruction, except worse since in the case above, the bullet is still moving, albeit slow. With an obstruction you get all the force of the powder charge acting on the gun: bulged barrel, blown out slide or receiver, etc.
