Really?
Well, another thread with the helpful insight of dla!
How many really want to know the truth? Really?
That gun did not blow up on accident. It blew up on purpose. Why? Because the reloader, whoever it was must not be able to read or they simply do not care, or, as some, they think they are THE expert on such matters.
I have successfully reloaded for a Glock 22 and done so with heavy bullets, 180gr without incident. YOU CAN TOO!
One thing that I do agree with dla on is that this "EVERY RELOAD BLOWS UP IN EVERY GLOCK" stuff has to stop, seriously. What those kinds of statements are really saying is: "I have no clue on how to reload for a Glock and you probably are too stupid to figure it out too!"
I had a KB once. Wanna know why? Stupidity, ignorance. Plain and simple. I think I need to say this though, it wasn't in a Glock! Ever heard of John Moses Browning? Yeah, the same guy that developed the 1911. Remember that pistol? The one that has been the standard for more years than you can count on your fingers and toes? Well, he had another pistol that was pretty famous too. What was it? The Browning High Power. Yeah, that one. Nowadays, they chamber it in 40S&W, or they did anyway. I had one. Since I had no knowledge at the time about unsupported chambers, since it didn't seem important to me, I didn't know that my wonderful Browning High Power had one, AND, one of the worst ones!

Just sayin'
Well, couple that with an uber fast powder, Clays, and a 180gr bullet and a maximum Lyman manual load that was .5gr over Hodgdon's maximum for that same bullet and guess what happened? Right, KB. The thing about it, I wasn't the only one to have that happen. There is another forum member here that had the EXACT same thing happen with the exact same components and we don't even live in the same state!
That KB taught me something, stop being ignorant, um, stupid. Know your equipment, know what possible dangers you are facing by reloading for said equipment and use some knowledge about what and how powders act and react and then load away.
If you use an uber fast powder in any cartridge, where or when rather, does it reach peek pressure? Right, before the bullet ever leaves the case. If you have an unsupported chamber, where is that case/bullet/pressure situation going to take place at in your firearm? Right, in the unsupported chamber before the bullet moves at all. When the bullet starts to move, what happens to pressure? Oh, it goes down. Hummmmmmm.
Okay, now ask yourself what happens when you use a slower powder. Pressure is not at peek right away, the bullet starts to move (remember, reducing pressure) and the burning powder tries to fill the increasing volume with more gases WHILE the slide is starting to move to the rear. So, bullet is moving, pressure is less but expanding gases is more and trying to fill that gap so the bullet keeps getting worked on as the slide goes to the rear and by that time, you have almost ejected the case, almost. This is over simplified for a reason, I am simple (in more ways than one)!
Seriously, know your equipment and be safe.
If you own a 40S&W semi auto firearm, see if it has an unsupported chamber, if so, load accordingly.
Here is a simple rule of thumb I use, if loading for the 40S&W in ANY semi automatic firearm, I NEVER use a powder faster than Unique, um, NEVER! Did I say NEVER? If not, I meant to.
Titegroup, is the wrongest powder that could be used in this caliber. I don't care how many rounds have been shot by gamers doing so either. Wrong, wrong, wrong.
If you want to know what I used, and successfully after the first KB for many years, it is SR4756. Lowest pressure, highest velocity of all of the powders I had on my shelf at the time. Now, it seems that Longshot betters it. Never got around to trying that one in the 40S&W. I gave a Square Deal B, my Glock 22RTF and all of my holsters to my #2 son in law. Oh, yeah, he has been reloading for that firearm for the last several years, same load, same bullets, same results.
FWIW
Just because one guy can't, doesn't mean others can't too!
