Lead boolits in a Glock?

[mohunter55]

I bought this book: http://www.amazon.com/Glock-Competi...=sr_1_1?ie=UTF8&s=books&qid=1306947336&sr=8-1

The Glock in Competition. It has a lot of very good information on reloads and lead bullets in glocks. if you are concerned I'd spend the money and read what Robin Taylor and the other glock experts have to say.

I think many that follow the notion of "Glocks never need cleaning" may end up with overpressure situations due to fouling/lead build up near the chamber end, especially with near max-over max loads.

If you shoot lead loads out of factory Glock barrels, inspect the barrel regularly for fouling/lead build up and clean as necessary.

I pick up and use mixed range brass. For this reason, I tend to keep my "Glock" loads in the mid-high range load data and reserve the near max loads for fully supported Lone Wolf barrels. Why? How do you know the person who shot the load before you did not use over-max load and over-stressed the case? I can't tell the condition of the brass that I am reloading, so I apply caution to give me some buffer "head room".

As to the use of aftermarket barrels, this is what Lyman's #49 says in the 40S&W section:

"Warning: Only use this data in handguns that fully support the cartridge in the chamber. If used in unsupported chambers, cases can rupture and cause harm to the shooter or bystanders."
