I am in the process of acquiring a .40 Glock 22 and just waiting for the paper work from the CFO's office before I can take possession. In the meantime I've started reloading some ammo for it on my Lee turret press. I just noticed tonight a warning on the load data tables that came with the Lee dies that said in bold letters: "WARNING - DO NOT USE reloads in Glock or similar guns with chambers that do not fully support the cartridge due to the intrusion of the feed ramp."
Since I don't have the gun yet I can't check for this yet. Does anyone know if the Glock 22 is in this category? How can the gun tell the difference between reloads and factory ammo? It's "close enough" I would have thought that it would feed ok. What happens if if I use reloads? Will it FTL, FTE properly? Can I do damage to the gun? This is a new (unfired) gun I'm getting so I don't want to wreck it on my first visit to the range with it.
Cheers - Rod

Gen one and some gen two Glocks had the Glock 'smiley'. My son has a gen 4 22 and there is no bulge when shooting it. I’ve loaded tons of 9 mm brass that came out of Glocks at my range and haven’t seen any bulged cases in a long time. They get resized and fired through my 9 mm’s with no issues. Are you reloading new or used brass?
 
I have a Gen 3 Glock 22 .40 and do not have a problem with Glock bulge. The bulge problem exists with older Glock barrels pictured below. The fix for the bulge problem was to modify the feed ramp to support the case better and the ammunition companies also made the cases thicker. The bulge problem can happen to any make and caliber pistol if the barrel does not support the rear of the case properly.

I also use range pickup brass and if I find any bulged case it goes in the trash. If these type cases are resized it weakens the bulged area and it might let go when fired again. Also there are many competitive shooters using .40 Glocks and range pickup brass and they just inspect the cases before reloading.

Below the type bulged case you do not want to reload.

The link below is the secret to long case life, just do not load hot, most of my reloads are in this category and land close and easy to find.

I have a gen 2 G23 with the unsupported factory barrel. I reload for it, but don't go crazy with the loads. Mild target loads have been problem free. I don't get the severe bulge shown in bigedp51's post. Also, if you have any Federal .40 brass stamped "FC", toss it. It is known to have very weak webs. "Federal" stamped brass is fine, if a little soft.

I'll be reloading once-fired brass and hopefully re-using those again. Just a reminder that this is a .40 cal.

Very interesting article - thanks for the link. In order to go with that premise of load low, I'm going to use starting loads of 4.4gr of 700-X. Bullet is 180 gr lead flat point (LFP).

That is not a "low" load.

Since it is a new gun, load a survey. Say, 10 each in 0.3 gr increments starting at 3.2gr up to about 4.8 gr. You will probably find that the gun has a preference for accuracy with a particular load. Mine likes 3.5gr.
 
If your pistol has an unsupported chamber that bulges the brass you can use this to fix the brass before reloading it again.

Shoot it first then evaluate if you need it or not. I've never owned a Glock older than gen 3 but I've never had any issues reloading for them.
Do not shoot lead projectiles though, you should shoot jacketed projectiles only to avoid lead buildup and increased pressures. The polygonal rifling likes to hold lead more than other types of rifling. If you do shoot lead just be sure to keep an eye on it and clean a little more often.
