My first post on this forum.
Ever since the advent of Polygonal rifling in the Glock and HK line of handguns, all I have ever heard was that you could not shoot lead cast bullets thru these types of rifled barrels with out excesive leading which would cause pressures to skyrocket. Well with the hyperinflationary cost of ammo and components to reload our ammo I had to put this to the test.
My test weapon is a HK USP Tactical 45acp. I have fired well over 500 rounds of 200gr. SWC lead bullets thru this weapon with out any exvesive lead buildup period. I cannot say the same for the Glocks, never owned one and never will.
I would fire 25 rounds thru my HK, stop and check to make sure. Suffice to say the lead buildup never happened and what little build up there was, would be removed with a few swipes of a bore brush and standard bore cleaner. So if anyone has these types of rifled barrels and would like to experiment with lead bullets, just stop and check after you fire a few rounds and check your bore.

RouteClearence,
Welcome to the group. I have heard the issues with shooting lead through a Glock, but not about the HKs. My middle son has been shooting a P7 for a good while with lead bullets. I do own a Glock, but have never shot lead thru it. My Glock has a different purpose, light weight carry.
Again welcome to the group.
Jerry

| I've known of a couple of Glock kabooms, read about a bunch more. It does seem that lead bullets and Glock's polygonal rifleing aren't a good match. The odd thing is, polygonal rifleing dates back a long way, the Henry rifleing of Martini-Henry fame is a type of polygonal rifles, as is Metford (Lee-Metford) rifleing. There were other forms of it as well. I'm not sure if the problem is volume of fire (lots of people think nothing of blasting 500+ bullets downrange, with no cleaning), undersized lead bullets, partially unsupported case heads, or a combination of such. Maybe something else. If I had a Glock (I STILL hate the damned things), and I wanted to shoot lead, I'd buy an aftermarket barrel.

I have shot a lot of lead handloads through my Clock 23 barrel with no problem.
What may be the problem with lead bullets in these barrels is if you don't clean the barrel, and probably if you use soft lead. For some reason it seems the lead will build up more in hexagonal barrels and will eventually lead to over pressure as the round tries to squeeze through.
I only shoot hard cast bullets and I clean after each range session, usually a couple of hundred rounds. No problems so far and no plans to change what is working for me.
