Reloading for a Glock
Is there any special precautions I need to take before loading for a Glock?

Re: Reloading for a Glock
What caliber?
If you are loading for .40 S&W or 10mm then stay away from hotter loads because the chambers are not supported as well as other guns and aftermarket barrels. |

Re: Reloading for a Glock
Then my above advice about avoiding hotter loads stands. If you want to use higher pressured rounds and/or lead bullets then an aftermarket barrel will kill two birds with one stone.

The 10mm GLOCK, I shoot, and pushing a 180gr xtp at fps 1385 has no ill effects on my brass crony says so and before I own a glock purchased a Lee Bulge buster anyhow I also use a Lee factory crimp die as well and after I crimp the round after acheiving the COL I do push it through the bulge buster just to ensue it will go into battery. No I won't tell you what powder is as it is not in the safe zone in print ''sorry''

Re: Reloading for a Glock
The lead buildup in an polygonal rifled barrel is higher than when standard rifling is used. In theory, it isn't much of a problem if the barrel is thoroughly cleaned after each shooting session, but it is still not advisable.

Older Glocks had an issue with unsupported chambers giving a few folks who loaded very hot loads some issues |

What do you consider older? This is an 05' model.

There really isn't any special precautions you have to take. I've shot bunches of reloads through my Glock .40s even with lead bullets. Lead can work, but you have to keep your eye on it. If it leads really bad, work up a different load. I've shot lead through Glocks that barely lead at all, and I've shot some that leaded terribly.
It's easier to stay with jacketed or plated, but it's also more expensive. |

I would say you're either dangerously over book max or your chronograph is messed up, it can happen easier than you think. Too close, not level, bent rods, bad lighting can all drastically effect your readings. The got over 1400 fps once with the 10mm G20, but the load was way over book and I was using a 6" aftermarket KKM barrel. Plus, 1385 fps is too fast for a 180gr anyways, 1200/1250 fps is more than enough. I stopped loading for the 10mm when I found that the .40 can wring out enough velocity to take full advantage of the JHP bullets anyways. With the 5.3" G35 and Longshot, I can scrape 1300 fps with 180gr JHP/hardcast, so what's the point of exceeding that when that's already more than fast enough, too fast really. |

As I reload for this cal, and have verifiey mulitiple times with crony, you results are less than mine as I have shot the 180 in gel,water,jugs, and I have modified the xtp results are always fully expand without much of weight loss.... this is again handloading and reloading used cases without excessive case damage... ymmv

At any rate, if you do shoot lead through a Glock (understanding that Glock and other experts on the topic strongly recommend against it) you should be aware that you should NEVER run a jacketed or plated bullet down the bore after shooting any lead until after the bore has been thoroughly cleaned and any/all leading has been completely removed. It would also be very wise not to push the envelope at all in terms of trying for maximum velocity since you're already essentially ignoring one known risk factor.

I have a Gen 3 Glock 20 and have worked up to max propellent charges for a few bullet weights as well as shot some Georgia Arms +P 10mm Auto loads and have had no case bulges.
Full length resizing does the trick and I continue on.

Re: Reloading for a Glock
You can run lead in a glock. Just CLEAN YOUR GUN!!!! I like running a few FMJs at the bottom of each mag to help clean it out too. But you need a solvent to keep it clean. Do it after each outing.
Or just get an aftermarket barrel. Or shoot plated bullets. Keep you loads light and you'll be good. Ike |

The jacketed round shot through a leaded bore will cause pressures to skyrocket. I've seen a report of one G19 blown up by shooting a single jacketed round after shooting one box (50 rounds) of lead bullet rounds. In general, shooting jacketed rounds through a bore that is potentially leaded is a practice that should be avoided in any pistol, not just Glocks. Beretta specifically warns against it in their owner's manuals saying to "DO NOT ever" (their emphasis) employ this practice. Allan Jones, ballistician and reloading expert for SPEER also recommends against it, saying he's seen a number of guns damaged by the practice.

When I first bought my 40 Glock I read several stories of shooting lead that resulted in kabooms. The issues ranged from unsupported barrels to the type of barrel used on the Glock.
Were they true? I don't know but for around $100 I bought an aftermarket barrel and shoot a lot of lead out of my Glock. It has been around 5 years and I have not had one issue shooting lead. So did I have to do that? I still don;t know but there are hardly any if in fact any stories of Glocks with after market barrels failing with lead. I was always told never to follow lead with a jacketed bullet so I never have. Here is some information on the type of barrel used in the Glock. Maybe it will help you decide for yourself. http://en.wikipedia.org/wiki/Polygonal_rifling |

Take a look in the reloading book at the operating pressures of the 10mm. A little common sense is in order when stepping outside the recommendations of factory literature. |

My G17 (only polygonal rifling barreled gun that I own) holds 17 so I load up a few FMJS and fill the rest with my lead bullets in each mag. I may have to rethink my practices regarding this. I clean my barrel/gun after each outing too regardless of wether I'm shooting lead or not. I really appreciate the post. Learned something new. Thank you.

The way it was explained to me years ago was the copper (from the FMJ) being a harder substance would help to "scrape" if you will, the lead out of the bore if fired after every dozen or so lead rounds. Obviously (unless you're running close to max loads, which is not wise in a 10mm being the high pressure round that it is) the barrel won't be leaded. it made sense to me and never thought twice about it. From the previous responses I have learned that this method is flawed and it has caused me to rethink my habits when shooting lead through polygonal rifled barrels such as glock or H&K. I am aware of the pressures that the 10mm cartridge operates at and would kindly ask that you give me the benefit of a doubt before accusing me of lack of common sense and the ability to open a manual and notice pressures of a particular cartridge. It is apparent that my method was flawed and I appreciate that they called me out on it. I'd hate to be the one to give out bad information. that's the beauty of this forum. The right information will usually come out and we can all learn something. I don't know everything and don't claim to. I learned something new today. But there is a way you can correct people without insulting their knowledge or lack of common sense. We're all friends here and share the same passions. I'm just asking for a little respect as a fellow reloader and shooter. Thank you. Ike |

I have not shot Lead in the Glocks. I did shoot 300 gr Cast bullets in my Ruger 44 carbine rifle. Then I shot a jacketed bullet. When the jacketed bullet hit the Leading in the muzzle, it split and peeled back the muzzle like a banana. [Evidently this is common.] Unlike Glocks, there are no replacement barrels for old Ruger carbines. It now wears a Marlin 444 barrel with part of the chamber cut off and with a gas hole drilled. [Now heavier and more accurate than stock]

I bought my G17 in 89 and I shot a bunch of lead through it before I had ever heard of the lead issue. What I have learned is that jacketed bullets are much more accurate. I never shoot lead through it any longer although I would not worry about the kaboom issue if I did. I clean after each 200 or so rounds.
