Cast bullets for a Glock?

    I am going to start casting bullets for my new glock 22 (40cal). Some say I dont need to change out the barrel other say I need to, so what's your thoughts. And what would be a good mold. I am going to use wheel weights.

    It depends

    It really depends on what you are doing. I personally would not shoot them in a .40 unless I was really shooting some soft loads.

    I shot them out of my stock glock 21 barrel for a long time. I never had a leading issue, at least not more than with any other gun I own. The key is to get a bullet that is hard enough, and sized properly, and dont push it hard.

    For example, one of my pet loads was a 200gr LSWC loaded over 4.6gr 700x with a Win LP primer. That load is well under max and was soft shooting. Velocity never got up there enough to be a leading issue.

    A good mold would be one that matches the diameter of the barrel after you slug it to find out what size mold to buy. Shoot too small of a bullet and it will lead like crazy. I like cast iron molds, don't have experience with the aluminum.

    there is a sort of lube you can purchase to coat each cast bullet, let dry and it will greatly decrease the leading of your barrel. I am sure someone will be along to tell you what it is called... friends of mine (glock shooters) have had good success with it.

    lead bullets

    I know of people that shoot lead bullets in their Glocks all the time but for around $100.00 you can buy a dropin barrel with cut rifling that you won't have to worry about. Go to www.lonewolfdist.com and check them out.
    The folks that shoot lead bullets in their factory barrels usually carry one of those bore snakes in their range bags and use it every couple of 100 rounds.

    If the lead builds up in your barrel it will cause high chamber pressure and I've seen the glocks blow out the extractor and do strange things.

    Lone wolf even makes different barrels that will fit in your gun (9mm) which is chaeaper to shoot than 40s&w.

    Well, considering the fact that the book that came with your Glock specifically tells you NOT to use cast bullets, I'd say you need to change to an aftermarket barrel.

    It also says not to use reloads, just like almost every other manual for every gun made. Big deal.

    actually I run a boresnake through all my guns after 50 or so rounds @ the range. Can't hurt.

    "It also says not to use reloads, just like almost every other manual for every gun made. Big deal."

    In case you didn't notice there's a difference between reloads and cast bullets. Every manufacturer cautions against reloads for liability reasons - reloading done right is harmless; Glock cautions against cast bullets in factory barrels because there's a good chance you can blow up the gun...simple enough for you?

    Do what you want...it's your gun, hands and face, not mine.

    Because, independent of pressure, and related solely to the presence of lead, Glock barrels instinctively know to disintegrate when contacted by cast bullets, despite the fact that polygonal rifling provides less nooks and crannies for lead to build up in than traditionally rifled barrels, and that careful load data has been observed... but only Glocks know to do this.

    I've put thousands of cast bullets through a handful of Glocks, with nothing more exciting to report than accuracy and inexpensive ammunition. My favorite 40S&W mold is the Lee #TL401-175-SWC 175g LSWC mold. Fed very well in a Glock 22 and 23. Just don't walk under any ladders or open umbrellas indoors. :)

    :confused:Putting an aftermarket barrel in your Glock also voids the warantee.

    Shooting lead is not a problem as long as you
    use hard cast bullets, 19 BHN (Bernell hardness) or harder;
    check the chamber and barrel often for leading;
    shoot loads around 900 fps;
    clean the chamber and barrel more often than with jacketed.

    A periodic scrub with the Lewis Lead Remover is a quick and easy way to make extended shooting possible before cleaning.

    Shooting jacketed bullets after lead bullets in polygonal barrels is controversial. Does it clean out the lead??? It is theorized that in reality the jacketed bullets irons the lead to a shiny flat coating and the bore is decreased. I personaly don't shoot the jacketed bullets to clean out lead.

    There is no need to get snotty about it. Keep it high road.

    Have you ever shot lead in a glock, or even own a glock? How much research have you done on it?

    Actually you dont even have to load the lead rounds, just simply place them in the same range bag and you are in trouble.

    Whats funny is that when you explain the mechanics of using lead in a glock barrel and what to watch for etc, there will always be someone there to tell you that you are dumb and whatnot. Never mind the fact that we have been shooting lead out of glocks since the 1980s. Yet to blow one up either, I wonder why?

    I could have been a little less snotty myself, I just hate that largely unfounded rhetoric gets passed on as natural law. Apologies to dullh for being a jerk; I didn't need to lay on the sarcasm... lastly, an overdue and ill-timed welcome to THR. :)

    You can most certainly blow up a Glock with reloads. You can also blow up a Les Baer with reloads, as well as an Ed Brown, Sig, and H&K. I bet there's a Freedom Arms revolver that's been blown up, if we dig hard enough.

    Moral I was looking for was stick to published data, and worry not. A good part of the economy of reloading comes from not replacing our gear every range trip. :D

    Right or wrong I have loaded and fired cast lead bullets out of a Glock 27 with out any problems. If I still had it I would continue.
