    Shooting Hard Cast Lead out of my Glock 21

    Does anyone shoot hard cast lead out of their Glocks. I read were you should not do it due to the Polygonal rifling and lead build up. I spoke to someone that competes with a Glock and thats all he uses with a stock barrell. I have tryed it out of my Glock 21 a do not see anything but normal fouling. Just looking for opinions.

    I would think commercial hard cast wouldn't do as well in the glock barrels as jacketed.
    Most are pretty hard say 17-21 bh.
    A flat based bullet cast @ 10 bh would possibly be soft enough to make a good fit and seal off preventing blow by which causes the majority of leading. You would still need to check after every session for leading especially at the throat.

    This has been gone through at least twice in my short time here, one time pretty extensively if you want to search threads. The results are 50/50, of corse its not recommended, but no manufacture recommends hand loads.

    A very mild lapping might help prevent leading, but the glock barrels being hammered shouldn't really be in need of lapping.
    "buckets of bullets" thats how you get better, if you think your pretty good, shoot another 10k rounds and you will be better.
    Its just my opinion, I tend to prefer them over yours!

    Glock does not "recommend" that one shoots lead bullets and they, like all other manufacturers, state that their warranty is voided if you shoot reloads.....

    I guess it comes down to your knowledge, experience and habits regarding cleaning and maintenance. If you know what you're doing with the boolits and use the correct boolit and correct charge and stay "on top" of your cleaning and barrel care, with a .45 ACP you "may" not have any problems. I don't have a Glock in .45 ACP, but I shoot a lot of lead in my 1911. I know others that shoot lead in their G21s, but most use an aftermarket barrel... but not all.

    Glock's "polygonal" rifling is more sensitive to lead build up due to it's unique lands. The "warnings" are because of the difference with the lands the leading issue (which can happen with any barrel by the way) gets dangerous "faster" with Glock's rifling than "standard" rifling.

    If it was me, I'd spend the $100 for a Lone Wolf barrel, 'cause I hate cleaning lead out of barrels. I shot some too soft boolits out of my 1911 and it took me almost an hour and $15 worth of "Lead Away" to clean it up. But, that wasn't the barrels fault, it was mine for using the wrong boolits.

    Using The Complete Glock Reference Guide (3rd Edition) as a source, I found the following excerpts that respond to your question:

    "The lack of lands in the polygonal rifled Glock barrel tend to allow a lead bullet to skip down the bore rather than spin, leaving larger lead deposits while creating build up and reducing the bore diameter. A restricted bore builds excessive pressure."

    "Federal Ammunition has offered a lead .40 S&W cartridge that works very well in Glock handguns. This is because the lead is very hard and does not foul the barrel at the same rate as traditional lead cartridges."

    I don't know anybody who shoots lead in standard Glock barrels in competition, but then I don't have that many friends. As EdF702 suggested, getting an aftermarket barrel for a Glock is a pretty good answer. I use one in my G35, not because I want to shoot lead but because I use a compensator, and the barrel is threaded.

    Federal no longer lists that .40 S&W lead round on their website, I did a quick check.
    Federal Premium - Handgun Ballistics

    It might sound counter-intuitive to suggest that you buy an aftermarket barrel to shoot less expensive lead bullets, but the peace of mind you would get with the aftermarket barrel might cover the cost.

    Which sort of gets me around to doing what I should have at the beginning of this reply, which is to ask why you would want to shoot lead bullets in a Glock. So, why do you want to do that?

    I've known people to shoot lead in Glocks... Most of them pay attention to the barrel and clean when needed... The problem starts when a new shooter or someone that just doesn't clean their gun starts shooting lead... It can lead to problems... sometimes big problems...

    For that reason the Glock factory and most experienced shooters on forums usually say... Don't shoot lead with a Glock unless you have a replacement barrel...

    The closest I will come is shooting Ranier plated bullets. They are double struck before the plating process. To date I have shot in excess of 2,000 rounds of .40 S&W with my G22 with the original barrel and have had zero problems. No fouling, no buildup, no excess copper from just being plated. Bottom line is I would rather suggest a plated bullet over the use of a lead round no matter the hardness.

    I shoot a lot and handload for my 1911's. I buy the lead bullits in bulk at a great price. I have shot 200 grain SWC lead out of my Glock 21 and see no lead build up at all. I also clean my pistols after each use.

    Cost is a great motivator, now I understand your reason for using lead. Cleaning them after each use certainly will help, and you may have found a lead alloy that resists fouling.
