    You shouldn't shoot cast lead bullets in Glock factory barrels because of the rifling. Glocks have polygonal rifling instead of lands and grooves.

  3. Yep, as a rule Poly rifling doesn't play well with lead bullets. You can pick up an aftermarket barrel(LWD, KKM, Bar-Sto, ect.) and shoot all the lead you want.
    Here's a good site for info on getting into "boolit" casting.

    I've been doing some reading and if u keep the glocks clean and load for around 900 fps it should be ok. Oh and harden the lead with tin or lineotype also it should be ok. Am I correct?

    I shoot nothing but lead, no issues whatsoever. Cast away

    Soft lead will leave deposits that build up and could eventually lead to a kaboom! I've experienced this personally. I shot cheap lead reloads out of my UZI pistol, that uses the same polygonal rifling as the Glock and HK. Afterward when I went to clean the gun, the barrel looked like silver colored bubblegum was inside. Luckily the gun didn't blow up.
    I've seen members on here and YouTube that blow through large quantities of lead without a problem. The reason is the lead is harder, added Linotype or other additive.

    Have shot thousands of the hard cast bullets through both the 40 and 9 stock Glocks with out any problems. The polygonal rifling picks up little to no lead and is easier to clean than standard rifling. The thing to look for is the hardness of the bullet. Check out this information given at one of the major casters website: http://www.missouribullet.com/technical.php

    Hard cast is the key.


    I've shot a couple of thousand of their reloads in a STOCK barrel with no problems. Very little lead fouling. They're lead is harder than the copper jacketing on "factory" ammo.

    If you do shoot "Regular" lead, run a defouler (birchwood casey bore scrubber) every couple of sessions with some 000 steel wool and you should be fine. YOu just need to make sure you're not really fouling the barrel.

    I've been shooting lead throught my Glocks for a long time, you need to pay attention to cleaning. People tend to not clean their Glock because they still function fine, but you can't do that with lead. I shoot a mix of lead and plated indoors and lead and jacketed out door, haveing 1 or 2 rounds of non lead in the mag will go a long way to prevent leading.
