I have a .40 Glock and am aware of the problem with the bulge in this round resulting from the high pressure and unsupported chamber.
My son purchased a 9mm Glock, and asked me if the 9mm has the same issue. What's the consensus about this?
Secondly, I purchased an aftermarket barrel for my .40 to avoid future bulging, but also because I heard of problems with heavy leading using cast boolits in stock Glock barrels.
Since then, I've read some posts about leading not being a safety issue in Glock barrels, if you only fire 100 at a time between cleaning.
I imagine that correctly sizing the boolit to the barrel is important, as well as boolit hardness.
Especially regarding the 9mm --
-- any tips on using cast boolits in stock Glock barrels with minimum leading (your technique)?
-- My Lee 90431 SWC feeds OK in my .40. Same type of boolit work well for 9mm?
Thanks
