Hey everyone, I'm very new to reloading and thus far have reloaded around 190rounds and have fired about 90 of them. The gun hasn't blown up yet, so I figure I'm either doing something right or just being lucky! From the other thread: I mentioned in THIS THREAD that I was shooting LRN bullets out of my G19, and it was brought to my attention that shooting these type of bullets out of a Glock can be a bad thing. I hadn't heard this before, and I originally assumed that was because of the short OAL required due to the shape of the bullet. I'm seating to around 1.072 s they will chamber, and from what I can find online about this type of bullet this is a safe thing to do. So what is it about polygonal rifling that makes it inadvisable to shoot lead? Just curious.... THANKS!
