BallisticianX: I can explain the technical reasons why if you reload you want to replace
your factory barrel, it is not just because the polygonal rifling with the
whole "can't use cast or plated bullets in a Glock barrel" It has a lot to
do with the case condition: All Glock barrels are designed with a
protruding feed ramp to aid in reliable feeding. This design offers less
case support than other manufacturers models. The larger chamber dimensions
of the Glock is also for reliability in feeding. The base/ web area bulge
issue is a direct result of the lack of chamber support. It is more common
to the .40 than the 9mm. The .45 is the least as the standard operating
pressure of the .45 ACP is much lower than the two latter thus less
expansion potential. The bulge is a serious factor for reliability when the
cases are reloaded as standard sizer dies cannot contact the case low
enough to remove it and creates a bump stop to possibly stop the round
short of fully chambering in a fully supported barrel such as Lone Wolf or
KKM. It also posses a weak point for rupture when fired as a reload in an
unsupported barrel, the condition to cause the "Glock caboom". Redding
makes a sizing die specifically designed to remove the "bulge". I believe
it's called the GRX die. It is designed to be used as a stand alone sizing
operation on a single stage press. The case is actually pushed completely
through the die from bottom to top to ensure full surface area sizing. You
need to do it to safely and efficiently reload Glock .40 brass for use in
any .40 chambered weapon. If your a reloader and want longer and safer case
life it is a must to have a supported chamber and a touch tighter chamber.
Simply rounds fired through a supported and tighter chamber expand less and
wont bulge thus less material to displace when resizing them back to SAAMI
dimensions., and no bulge hindering safety or reliability. All brass
material will have a phenomenon called work hardening occur when constantly
pressed or expanded under force. How quick or hard depends on frequency of
the force applied and how much per instance. So the less it is moved per
instance the slower the process takes to become a problem. Once a case is
work hardened it loses ductility and increases density and is less likely
to flex but rather crack. Now you increse rupture risks and another
condition called spring back. This is when its to hard to be forced to a
dimension and stay there but rather will expand back somewhat from the
desired dimension applied to it from a loading die. This makes for
oversized cases to increase feeding problems and less than optimal bullet
tension for erratic pressures. All brass eventually should be retired but
over expanded cases will have to be retired a lot sooner....not very
John Doe: I just sent my new LWD barrel back. It shot 5-6 inches too high. NOT GOOD.
Robert Watson: Few gun manufacturers were prepared for the IPSC phenomenon. Individual
shooters routinely fired more ammo through any given firearm than some
small police departments. Glock was no exception. They were developed as
military sidearms and would never see the amounts of ammo a dedicated
shooter would expend. The bulging issue would not be a factor for a
military weapon since the empty cases would not be reloaded.
Dixie Normus: Is this only for .40 s&w barrels or do Glock barrels do this in 9mm,10mm,
.45 as well?
theytookmyfuckiname: is this a gen 1 because i was told they fixed this problem after gen 1
James Sorrentino: From a logical point of view, I tend to agree with you. However, I have
seen certain factory loads (Personal Defense) that won't chamber in the
Lone Wolf barrel. You want reliability and chambering of any ammo - Glock
barrel. Sticking to one type of ammo - Wolf barrel may be advantageous.
The Glock is not dangerous. It's the most widely used and most often fired
pistol in the world.
usabirddog: thanks dude for the vid
Lee Greger: Actually, .006 is huge. I was a machinist and we worked with +- .003. Even
what we did would be considered lose. Great video.
Erick Trisha: Thank you for your input. You managed to answer a few questions that have
been bugging me.
Aaron mann: Nice video. have recently just acquired a Gen 4 G35 .40 cal and I love
it. Used to be a 9mm fan and still am for cheaper cost. How much do you
actually save reloading your own ammo vs buying factory? I want to get into
loading my own but I want to see if it will be cost effective before I buy
all that equipment. I can go to my local sports shop and get a box of 100
165g target loads for $35 or I can order bulk on line for fairly cheap. I
was afraid of KB at first so I ordered a LW threaded .40 barrel for it so I
can be "safer" and use a suppressor. I have shot about 50 reloads and about
500 rounds out of my stock barrel and no problems. Glock rocks. Everyone
has a 9mm and can shoot good fast groups but I just love the .40.
lazerusmfh: I have no problems reloading 40 S&W and firing in my glock, and SIG. Both
cycle fired brass from the glock no problem, and haven't had problems with
cracked casings. YMMV !
amaya1000rr: @surfboardhacker - Thanks.
DON C.: I would & did spend the 109.95 from LWD so i could reload.Never had a
problem.Case weaking if you reload it will pop over time then you have a
glock kaboom.Good video
Bon Jovi: Guys... Your cartridge doesn't headspace the way you're thinking it does,
nor does that barrel support that case in the depth it appears when you do
this test. Put that casing in your magazine, put it in the gun, then rack
the slide and chamber it that way. Look at what's keeping that casing
still; it's the casing stuck against the bolt face because the extractor's
holding it there. Now look at the breech block of your barrel. See the
surfaces that are holding it away from your slide?
Rick Odato: Thanks for a very informative video. It clears up a lot of questions that I
skiboyscuba: Thank u
amaya1000rr: I've probably reloaded my .40 cases 4 to 5 times now and haven't had any
problems. I keep my loads on the lighter side for range use. I use new star
line cases for anything hot, but since I also reload for 10mm I never try
to push the .40 too hard. Honestly I think the infamous .40 kaboom has been
blown way out of porportion. If you stay within published data and are
careful about what your doing, you'll be ok. I still like the added safety
of an aftermarket barrel, just for peace of mind.
lancerooke: Here's why I bought a lone wolf barrel. I bought a Glock 19C, but I'm not
interested in the compensated barrel for conceal carry. Don't wanna be
blinded if I have to shoot at night. So no big deal, right? Just buy an
uncompensated lone wolf barrel. Great product IMO. My only complaint is the
stupid cartoony image on it. I disagree with you on the reliability of the
lone wolf barrel. I think it's just as reliable as the stock Glock barrel.
Do you have any stats to compare the two?
georgia bowhunter: Nice video. Well organized and informational. Keep it up. I use the same
40-9 barrel in my G23 and G27. I also have the Lone Wolf .357 SIG barrel.
excelerater: you can have wolf make your WOLF barrel machined for reloads,they will add
a small taper so its not so tight,,,I have since sold my wolf barrel and
only use glock barrels in my glock...but I have seen and heard wolf doing
this process for reloaders such as myself.......
wilmerpetcock: Great video man. Answered alot of questions. I just got into reloading
.308's and have yet to load any .40's. Already have the dies, just not
started yet. Is it considerably cheaper to reload the .40's as opposed to
buying factory ammo? Also, as with my .308, will reloading .40's help with
accuracy? Factory .308's hold about 1.5 inch groups, my handloads just make
the hole bigger. I've run more than 8000 rounds through my G22, so I'm
already pretty accurate. (-10" group @ 100yds) Love my Glock
David Louis: you dont carry a round in the chamber???? ehhhhh...why carry?
Fergesslich: Still better than no gun.
amaya1000rr: @wilmerpetrooster - I'm glad you liked it. I've been able to save around 40%
on average in reloading .40s&w as compared to buying factory ammo for range
use. Problem is I shoot twice as much now. If you decide to handload for
self defense (hollow point) rounds then you can save considerably more as
compared to premium factory ammo. IMO you may not see much improvement in
accuracy by meticulously hand loading ammo like a .308 rifle. Most pistols
just aren't as accurate to make it worth wild.
m parch: great video. gonna guess they do that for low tolerances. reliability the
cartridge will make it in the chamber. not built with the intent for
reloading at the range. great video. thanks dude!
mguinthe: Very informative. I don't reload, but I watched some videos that confirmed
my experience that Double-Tap 10mm flat nosed bullets can tumble in a
standard Glock barrel. The Lone Wolf barrel has much tighter tolerances,
which makes a 10mm bullet fly truer than a standard Glock 20 barrel.
Exactly what I needed to confirm. Thx.
amaya1000rr: Thanks for watching.
jris211: Contrary to popular belief, you can fire lead rounds through your stock
glock barrel. That is a very common internet myth
InlandEmpireDudes: Just the video I was looking for! Informative and awesome! Is the glock
factory barrel in this video the newer "more supported chamber" barrel
glock release post 2010ish (signified by a dot within the pentagon marking)?
Ralph X: OMG! I've been reloading 40 S&W for the Glock 27 since it was introduced in
1991. That's 22 YEAR - so I know what I ma talking about here! I NEVER had
a KABOOM in thousands of rounds! I use the same brass 4 to 5 times and
discard it after 5 times. This video it pure BULL! There is nothing to
worry about! Just don't load to excessive pressure and you will be fine.
The KaBOOMS happen when reloader try to get creative.
theroyalgrapefruit: very informative video, should have more views!
Chris Crawford: Good video
TheFireArmGuy: Great comparison and explanation of these barrels
amaya1000rr: @DunrominFarms - I'm glad you liked it. Thanks for watching.
amaya1000rr: They all buldge to some degree. 45acp opperates at about 20,000 psi where
.40 s&w opperates at around 35,000 psi. This stresses the brass more
creating a larger buldge which work hardens & weakens the brass when
resizing. The .40 s&w really pushes the limits & that's what makes people
nervous about reloading for it.
amaya1000rr: @donthebodyguard - yea, it's definately worth it for the added peace of
tttdub: It's because of the rifling, not dimensions.
001SteveK1: Good info, thanks!
Tony Briggs: nice job...
jris211: Don't panic about it. The lone wolf barrels are match grade. In other words
their chambers are way more tighter than most guns, not just glocks. Go
ahead and reload them. The resizing die will do fine on the glock fired
brass. You're gonna find out that all this "unsupported chamber" nonsense
is just that. Nonsense.
surfboardhacker: This was an excellent review! Subbed
amaya1000rr: Not sure how the rifling would make a difference since the case sits within
the chamber and does not touch the rifling. Maybe there's something I'm
missing, please explain your theory.
Red-Neck AznDrummer: I have a Glock 22 Gen 4 and The rifling didn't look like it had the same
barrel as you are showing as in rifling. I have copper plated lead at .401
dia 165gr, should I still buy the lone wolf??? Thanks
flysubcompact: I noticed that this video was made in Jan 2012. How is it working out since
you made the video? I'm in the same boat. I just started reloading (9mm)
and had concerns after looking at my bulged .40sw cases. I would like to
reload the .40's for range use, too, eventually.
