So I shot cast bullet in my factory glock barrel...

Always shoot reloads in all my guns including Glocks, but I use copper plated bullets I wouldn't shoot lead esp in Glocks stock barrels. If you really want to buy a lone wolf barrel they're pretty cheap.

As for bulged cases, older generations of Glocks had that issue. Gen 4 has a better support I remmeber when I had G22 gen 2 and 4 there was quite a bit of difference.
 
I've shot hundreds of hard cast lead bullet reloads thru a G22 .40 cal with no ill effect.

Make & use proper ammo, keep your gun & barrel clean.

No problemo!

Lead bullets will eventually lead up the polygonal rifling in Glock barrels. I have seen it to the pint where there were actually ribbons of lead filling the polygonal grooves. The owner who brought me the gun actually though the steel was peeling off the inside of the barrel. Laugh2

This really only becomes an issue if the gun is used extensively without being cleaned. With proper cleaning & normal maintenance barrel leading should never be an issue even with a Glock factory barrel.

Yup, "Do not listen to all the myth and misconception out there on the wild internet. "

Read some joker did a meager sampling of "198 cast bullets out of my G17 today" and with that declared it is safe to shot lead in a polygonal barrel.

So moral of the story: DO NOT LISTEN to internet advice.

Yes don't listen to the internet. Try it yourself like I did. It works for me, I never said it would work for everybody.
I don't know for you but for me 200 round is a good range trip. I don't need to know if I can shoot 5000rnd of cast without cleaning simply because I wouldn't do it in the first place.

I haven't tried anything other than jacketed projectiles in my G20. I might try it just to see the results.

OT, but since it was mentioned in this thread, I will say that my factory 10mm barrel leaves the casings bulged. I have a Redding G-Rx die that reforms the bottom of the case. I can't say if there is excessive case wear as I have not shot a lot of reloads yet. I shoot .40 through a Lone Wolf barrel in the same gun and I do not have bulged casings. Maybe a tiny bit but I full length resize them in the G-Rx anyway since I tumble the brass, then G-Rx, then sort.
 
My G21 would start showing signs of leading up at about a hundred rounds and by 150 was concerning.
A couple of passes with a brush and all was well, what I learned;
-Know the risk.
-Monitor the issue.
-Ensure you do control measures to mitigate the risk.
-Continually repeat and enjoy.

As for case bulging I've only seen it in older G22's but I haven't played with a gen4 yet, so...?
-YMMV
 
I run a brush through pistol barrels as I transfer from the range bag to the locker. 99% of ammo is lead. Don't see much difference between Glocks and the others. But only shoot 100 or so per pistol, per range outing.
 
It is not a myth and misconception that one should only shoot lead out of a glock barrel when they know what they are doing.

Combine your OP that implies lead is safe to shoot lead out of a Glock along with Glocks can be abused with shooting thousands of rounds without cleaning can lead to disaster.

Already enough anecdotal stories in this thread about peeling lead plus lots of good advice on keeping an eye out for leading and cleaning so leave it at that.

Amount of leading depends a lot on the kind of lead cast bullets, bullet shape, power factor.
So what type of lead (WW, lyman #2, lino) did you use?
shape (RN, SWC)?
Power factor powder puff, med, factory load.

With plated/jacketed don't have to worry about it :)

I have seen exactly the same thing in a rifled 45 ACP barrel. This is not confined to polygonal rifled barrels.
 
Glock's manual advises that you should NOT shoot lead. However, if you maintain and clean your Glock pistol on a regular basis, shooting lead based bullets should be fine.

So your choice is to listen to the Glock manual or the internet. ;)

Bullet fit and choice of lube also play a large role in the amount of leading you will get. The same load/bullet I use in my Glock 19 causes more leading in my Hi-power. Bottom line, experiment, monitor and go carefully. I don't have the option of using an aftermarket barrel in my Glocks as they are all 12(6) and I don't want to change them to restricted.
