Thoughts on hardcast lead in Glocks please???

Last month. Here's what the instructor said,if it is your self defense weapon don't modify your Glock trigger and don't run reloads or lead bullets in it. If it is going to be a competition or play weapon that's a totally different horse of another color. I have a friend who competes and has several Glocks he has modified and shoots home tolled lead bullets extensively without issues. But he does a lot of shooting and changes barrels frequently in his pistols, at least annually.

Standard rifling, for plinking and paractice with cast.

bullet to fully fill it and take the rifling. Some friends who really looked into the situation told me they found a 0.403" 10mm cast bullet was what it took in their test gun to perform the very best. Sure a .400" will work but don't be surprised if you find lead streaks in the bore later.

Glock's official word will always be NO RELOADS period.

I use aftermarket barrels with conventional rifling and tighter chambers. Glock is chambered very sloppy by minimum SAAMI specs., that's why they run 100%. Like an AK.

I do very naughty things with my Glock, they are engineering marvels. I think I remember the original Desert Eagle .50 was a .510 Polygonal design but the Govt. test device limiting destructive devices to .51 cal. dropped right through the polygonal bore! They dropped back to .500 and the rest is history.
