Loading .40 S&W for Glock

[Cowboy T]

If you're going to reload for a .40 S&W Glock, I'd suggest two things.

1.) Lone Wolf aftermarket barrel. They're $99 at MidwayUSA. Fully support the round, and use traditionally cut rifling. The latter characteristic is more forgiving of "too hard" cast lead bullets if you use those. I use cast bullets in all my guns because they're inexpensive and thus let me practice a lot more.

2.) Lee Bulge Buster Kit. It operates on the same principle as their bullet sizer to "de-Glock" any brass you run across. At roughly $30 including the die body, it's cheap insurance.

Armed with those two things, you're ready to rock 'n' load.

I saw some bullets made by laser cast, they are saying thya they wont lead the barrel....i own a fully functional glock and i want to keep it that way. I understant that the barrel ofg a glock is unique.....polygonal/hexogonal ????? what is this, how does it affect what i load? I just want to be safe..if there is another post where this issue was resolved please let me know as i havent found it yet

Nothing....

do a google search for polygonal rifling. You'll turn up some images of the difference. Basically the shape of the rifling causes non-jacketed bullets to lead excessively. You can shoot lead boolits through poly rifling. you'll just have to clean much more frequently to avoid a possible high pressure situation. Stick to jacketed or plated bullets, and you'll have no problems.

Wow, mister impatient here. Post was barely up for 5 hours.

This is what popular research will tell you... I can't back it up since every friend's glock has had an aftermarket barrel lol. Changing barrel doesn't make it stop being "fully functional".

As others have said, you can shoot cast lead bullets through polygonal rifling. And yes, there is a way to avoid all that leading. What you need to do is match your load's pressure to your alloy a lot better than most people do. That is a big, big help right there.

So is the consensus here that it okay to reload for a Glock 22 40 S&W? I have one I am wanting to reload 140 gr copper bullets for.

Since I posted this thread, I have loaded close to 500 rounds, 180 gr fmj over 5.0 gr Universal for a G22 gen3 with no ill effects. Standard Rcbs carbide dies, no Redding Grx or Lee FCD. I wouldn't go trying to set any velocity records, keep it sane and you should be good, I'd say.

I have a Gen 1 and kinda worried.

Check if your chamber fully supports the round. If not, then you might consider a Lone Wolf aftermarket barrel. Given that your own reloads are way less money, it shouldn't take long for that barrel to pay for itself.
