Ok, so I have been reloading for about 9 months now and shot countless rounds out of glocks. I have heard not to use hard lead none jacketed loads out of glocks but never understood why.. Any how i just started reloading .40 S&W's and noticed in my Lee die set (delux with factory crimp die) and I noticed in the paper work it stated " warning do not use reloads in glock or similar guns with chambers that do not fully support the cartridge due the intrustion of the feed ramp" now I knew it voided warranties in glock but I didn't know it was harmful.. Does anyone use reloads in glocks?

the problem with glock barrels is the goofy type of rifling and the severely unsupported chambers. the rifling is a type that is super cheap to make but reduces wear greatly. the downside is it leads up very quickly and very nastily which greatly increases the likely hood of a kaboom from over pressure.

reloading glocked brass on a regular basis and continuing to fire reloaded glocked brass also leads to kabooms from the unsupported base of the case hardening from resizing over several uses and becoming brittle over time. while you can do it a few times at some point your going to violently disassemble your glock.

glock barrels are designed by gaston glock who didnt know much about guns or gun design so he took shortcuts to enhance reliability at the cost of versatility and user safety.

if you want to reload for your glock get an after market barrel that uses more traditional rifling and fully supported chambers. then you can use lead bullets and reloads

Glock uses polygonal rifling, that is why you aren't supposed to shoot lead bullets through them. My buddy uses reloads in his glock 40 almost exclusively and he loads them hot, the Glock leaves a portion of the shell casing unsupported in the chamber, I suppose the worry is the partially unsupported chamber can be the cause of the dreaded Glock Kaboom, possibly increasing that chance with reloads of a hotter nature and brass that has been used a few times too many?

But bare in mind that it's not just Glocks that have kabooms. Any firearm can with improperly loaded ammo.
thats true to a point. but the unsupported chamber in glocks make it almost assured that continued reloading of glock brass ensures it will happen through the brittle nature of work hardened brass. in other guns that full support the case head area that portion sees very little stress compaired to a glock. any weakness in the case head area leads to kabooms in glocks. almost all the cases of glock kabooms are from overworked or slightly out of spec brass that wouldnt have been an issue in a barrel that didnt have a design flaw.

thats why you shouldnt reload for a glock with a factory barrel.

What if you have a lone wolf barrel? I plan to reload for my glock using the 9mm conversion in my G23. Is this also a bad idea.

Btw here is a comparison of the riffling. The first is my G23 the second is my XD45.
should be fine with a lone wolf barrel. they fix the design flaws in theirs and use better rifling method.

glock isnt the pioneer of polygonal rifling. hk and imi both use it in some guns. its been around longer than glock. any gun with polygon rifling shouldnt use non jacketed bullets. my desert eagle uses polygon rifling

In short glocks suck right? Lol go ahead and say it. I will agree lol. I got mine bc it's what the LEOs use in my area. So if shtf I can use there mags and parts. Only had the gun for about 3 weeks. (I am not impressed at all)

I'm guessing this would explain what is known as the "glock bulge".
Hmm...I thought "Glock Bulge" was from gangbangers carrying them "convict style"? :D

I'm a newb so please forgive me but...... Polygonal rifling sucks in a Glock but is the bees knees in your stainless barreled AR?

it only sucks if you want to use non jacketed bullets. it greatly limits your options in a ohsht type situation. glocks and polygon rifled guns are pretty much a no go for that sort of thing. if your planning on using a glock for ohsht end of the world get a different gun or replace the barrel.

Nope. That's a penny. The bore on a .45 is just so big it can fit a penny. Lol

Yea it's a live round. Don't worry tho I used a tripod for the camera and leaned to the side. And did not have my booger hooker on the bang switch. Also did not have the grip safety engaged. Plus it was a decapped casing with no charge. Trust me I'm not blowing my face off for a pic.

Well I guess that would not be a live round. But it is a real bullet.

Oh crap. I don't have to worry about this with my M&P 15 do I. I don't thank it has poly rifling.
