I have a buddy that says he can't shoot lead in his Glock. Is there a specific reason for this? I want to start reloading and was thinking of using lead in a 1911 to punch paper.
So do you just go to your local roof mart and buy some lead flashing and melt it down or something?
MOST reloaders, will go the cheapest route possible. This usually means going to you nearest garage, with a bucket and work gloves, and begging off some auto mechanic, the wheel weights from auto rims.So do you just go to your local roof mart and buy some lead flashing and melt it down or something?
It is not wise to shoot lead through any barrel with polygonal rifling. Leading in the barrel can cause increased barrel pressure.
If you want to shoot lead bullets buy an after market barrel with the normal lands and grooves in the barrel wall.
Providing you use jacketed or plated bullets. Probably 99% of factory 9mm is plated or jacketed for good reason.As a matter of fact, Glock itself advertises as one of the advantages of a polygonal rifled barrel is less fouling.
You have to take Glock's advertising with a huge grain of salt. After all, they are the guys who convinced mall ninjas everywhere that a turd-shaped gun with an unsupported barrel is "Perfection".Huh!
Every barrel gets leading if you use any amount of lead bullets. Matter of fact the leading starts with the first bullet. Physics. The chamber, forcing cone and barrel of any revolver that shoots say, 500 rounds in a day of PPC shooting has lead everywhere. Even well timed brand new guns, do. How would having lead in a polygonal barrel have increased pressure over a traditional land and groove barrel? As a matter of fact, Glock itself advertises as one of the advantages of a polygonal rifled barrel is less fouling. Therefore less lead or other material build up. So again, traditional barrels theoretically strip the lead more, and therefore more lead build up. So therefore the added question will lie, how does a polygonal barrel not withstand the pressures of a land and groove barrel? And HK, Glock and others will argue, the polygonal barrel will handle more pressure.
So, I've heard that rumor before, and always wondered where it came from. Other than anti Glock rumor web sites, can't find any real proof.

I don't know, as far as I know they don't. I didn't say they did.Where does Glock recommend shooting lead bullets through a 9mm barrel with polygonal rifling?
I don't have to talk to anyone as there isn't anyone alive the can detect anything about barrel pressure from shooting. There are probably only 2 pressure barrels in Canada. One at Energy Mines and Resources, and one at Colt Canada. There might be another, but probably not. Check that, Para Ordnance may have one as well. I don't know how active a company they are right now on this side of the border.Barrels with polygonal rifling lead up faster than barrels with lands and grooves. Talk to some guys with Browning FN's about lead fowling and increased barrel pressure.
Absolutely, but saying that, the question and answers given, talks about Glocks fouling and exploding more because of polygonal rifling. It just isn't true.You have to take Glock's advertising with a huge grain of salt. After all, they are the guys who convinced mall ninjas everywhere that a turd-shaped gun with an unsupported barrel is "Perfection".
. And that's the point. No less, no more. Again referring to the preceeding answers.From my experience with polygonal barrels, they foul no less than traditional barrels
Gotta be honest here on this issue as well, there is no documentation to support a longer service life with a polygonal barrel.There is an argument that they are easier to clean, because there are is no sharp change in elevation between lands and grooves, but this seems to be largely hypothetical. The real advantages of the polygonal barrel are prolonged service life and increased barrel strength (polygonal barrels are usually hammer forged, while traditional land and groove barrels are not).
The only problems have been documented are resulting from feeding issues with lead bullets combined with certain bullet shapes, ie. truncated cone. The feed ramp on most Glock pistols is fairly sharp. My opinion is, it is that design that increases the feed/fail to go into battery problems with lead bullets.Having said that, the only other major manufacturer who uses polygonal barrels in their pistols - H&K - does not warn against shooting lead. Perhaps there are other aspects of Glock's design that make shooting lead inadvisable.
They also convinced the majority of police depts with any type of budget in North America. Only our Fed dept in Canada would choose, 1. Gun in 9mm, 2. Gun with mag "safety", 3. Gun heavier than 2 Glocks, 4. Gun that needs a squad of armourers to keep them going. I mean come on.......After all, they are the guys who convinced mall ninjas everywhere that a turd-shaped gun with an unsupported barrel is "Perfection".
