    Pretty much the same amount of powder for the jacketed and cast bullet, but I hope you have a loading manual which would have shown you that.

    Anyone shooting lead bullets should have a manual showing them. Sometimes things are different...

    Some mfgrs PROHIBIT the use of lead in a 40.

    Very fussy high pressure cartridge, sometimes too high.

    Google glock kaboom or the like. I wont load 40's

    regards

    JHP and lead are two different animals. Less powder with lead because after 1000 fps you start to strip the rifling off the bullet where the jacket can be pushed a lot farther. I use 5.6gr of Power Pistol behind a 180 head head. All the usual disclaimers apply and load at your own risk. Be careful with brass from a GLOCK as they usually have a bulge at the base. Look it up, It's called the glock bulge or glocked brass. Watch out for cracks in this area. Get a good book and only use published loads and start at the low end and work your way up.

    Glock's have different rifling (hexagonal, I think) that prohibit the use of lead bullets. If you do use lead, you will have a real mess on your hands that will take a lot of cleaning to get rid of.

    Get yourself a nice S&W revolver. No bulged brass, shoot lead or jacketed bullets. Much more reliable and you don't have to wait for the slide to cycle inorder to shoot the next shot. HMB

    Glocks have a unsupported chamber. The brass will bulge at the 6'o'clock
    position in the chamber. Do not shoot lead bullets in a Glock as the
    lead will build up in the rifling raising pressure which may result
    in a Glock Ka-Boom.

    Lead and JHPs usually require different loading data in the .40. As said previously, an aftermarket barrel in the Glocks with square rifling and a "fully supported" chamber is the way to go. In general, Cast bullets should be driven to more reasonable velocities. Use the Jacketed stuff for the higher velocities. Use reliable data from a trusted source. The bullet profile can sometimes cause feeding issues in some guns.

    Most, if not all, manufacturers discourage the use of reloads in their firearms. So what?

    I agree with the "unsupported" chamber problems. Blew the magazine out of an old Smith 39 when a lead bullet telescoped into a case and raised the pressures too high (guessing on the telescope thing but not on the case thing as I found several of the same headstamp cases with bulges while picking up my brass).

    Had a 40, don't any more. Sold the dies, brass, bullets and all with it. Not out of any problems, just because I like my 45 acp and my revolvers more.

    Plan on shooting reloads in all my guns just the same as always. How are the manufacturers going to prove I did? Don't know. I use common sense with reloads, discard questionable brass, and don't load max.

    If you dont know the Difference you dont need to reload
    As for Glock they are {as some say supported} glock is design to shoot dirty ammo the chambers are larger to use ammo that got dropped in the mud.
    They make for a reloading problem but the gun will work it just dont make a target gun
    As for reloading ALL manufactures say NO RELOADS that is because of the Micky Ds law suit for hot coffee.
    Dont reload any thing is not worth the risk
