    Does anyone know if a lone Wolf barrel will eliminate the case bulge
    which is common with the Glock 22 stock barrel? I presently run all
    spent brass through a Redding full case sizing die, and would like to
    eliminate this step if possible.

    I can't provide any helpful information on LW barrels in 40S&W. I would think that they would be fully supported but I'm sure others will chime in.

    Are you referring to the G-RX die?

    How old is the BBL that you are using? Are you sure you even need it?
    I asked because the later Glock barrels do not have that issue as prevalent as the earlier. Glock has improved the BBL design over the years and added more support. They actually have just as much as any other manufacturer these days.

    I routinely reload once and mulitple fired .40 brass fom my G23 and other Glocks from once fired and abandoned from my local inddor range.
    I have yet to have a problem resizing a case with the standard dies in my Dillon SDB. In fact, just last night, I case gauged and checked OAL on 600 finished rounds that I loaded earlier in the day. Each and everyone passed through my Dillon case gauge.

    Have you tried just running it normally? I know lots of people who shoot .40 and never use any special dies. I run 10mm and don't need anything special. I have sized and loaded plenty of .40 and they all pass my case gauge easily. I use a standard Lee sizing die.

    I agree, back of the nuclear loads & you should have no problem. Dare I ask, are you using TG as your powder of choice? Try a med. burner for lower pressures w/ higher vel.

    I have a LWD barrel in 9mm but I have one on backorder for my 40 so I cant speak on that. However, I will say this, I bought 1k nickle 40 cases for a hell of a deal. Almost all were shot through police glocks and all of them are in spec. I know because I have a Lyman case guage. I had to run each case through my resizing die twice and it was gtg.

    A medium burner such as what? What is a good powder to use when loading mild loads for Glocks?

    I'm just glad I started reloading 40SW before I got the internet.

    I shoot 40 almost exclusively. I just use my dillion dies. Just make sure that you turn down the resizing die until it makes light contact with the shell plate.
    One of my g23 is a pre-order before they were even available. So its as old as G23 get. I don't have any problem with its brass.

    In the 40 cal LW barrels are 3 thousands of an inch tighter than my glock barrels. So its even more important with them than glock barrels that your ammo is at factory specs.

    As fred says just don't make barn burrners and you are fine. Try some win 231 or wsf or pistol power.

    I use Unique, Bullseye, and WSF right now. I do have some TightGroup but I am going to use it in some 124 gr fmg I have coming. I usually stick around start load. I have no use for max loads except in defensive loads.

    I have a LW barrel for my 40 that I use for practice. The chamber is definitely tighter than the stock barrel. A case that was shot from the stock barrel will not go into the LW chamber. I figure I can get longer life for cases if they aren't being stretched out and resized as much. I did get some ftf jams with the LW but that was only with a couple of mags.

    I recently went round and round trying to get my reloads to fit the LW 40 bbl.
    It is/was much tighter than .003 of an inch over the G23 bbl.
    The reloads would drop right into the Glock bbl, but the same rounds in the LW bbl would serriously jam the weapon.

    Everything is good till I crimp them (so very slightly) then it was a no go.
    I'm currently using lead bullets, hence the LW bbl. With FMJ rounds in the Glock bbl, no prob at all. Even when I had the G22.

    I have a 9mm conversion I plan on trying out tomorrow to see if I have the same issue.

    They are typically way to tight. This one guy I know buys them all the time. Nearly every single one of them gets opened back up. I had a 9mm LW barrel. I never had a single issue with it as far as feeding is concerned. But the guy who bought it from me could not get it to run with out opening it up. I know my sizing die works very well. His must not be as good, or he is doing something else a little differernt. They are just real tight and everything has to be perfect for them to run right it seems.

    Same here,

    I did invest in two Storm lake barrels for our G23 and G22 just for shooting lead. But I've reloaded for 3 different 40 cal Glocks for the last 10 years with no problem.

    I reload a lot of lead for .40 S&W and purchased a LWD barrel about six months ago. It is definitely tighter than my Glock 22/35 chambers. Most of the time, with my lee dies, I never have a problem.

    Every now and then I have a cartridge that won't chamber properly in that LWD barrel though. I usually case gauge all my finished rounds though, so it's not an issue most of the time. However, I just purchased an EGW 'U' die to try and remedy the problem. I will let you know how it works when I get a chance to try it.

    Please do let us know haw that die works.
    I was miking rounds right and left. All w/i spec at differant setting on the Dillon, but some I think some of it was the mix of differant manufactuers brass maybe.

    It runs fine now.

    Thanks for all the help. My G22 is an early model. I normally reload with
    W231 or WSF, but occassionally use Bullseye for a more aggressive load.
    I hardly ever use range brass. My normal brass is Winchester. I do get
    case bulge from the Glock. I haven't seen any bulge from a S&W model 410
    which is fully supported. The tightness of the LW barrel is now scaring me.
    A better solution may be to get a replacement Glock barrel. Thanks again.

    You do realize cases get bigger when they are fired? That's what a resizing die is for. I never understood why people think their brass should come out of their gun already resized. The Glock bulge is a myth.

    The only bulges I have seen in my life, and that includes firing or being amongst groups of people firing, hundreds of thousands of rounds, is when the load is too hot or once when my buddy was shooting his SW99 with Win USA. That SW99 bulged those factory rounds so that there was an obvious pregnant bulge. In my Glock I had some loads that I made with HS7 that bulged the cases the same way. The loads were below max and were too hot. Sucky powder now discontinued.

    If your cases are bulging down into the feed ramp, your load is too hot, not your chamber too big. If the cases are just bigger after firing than before, that would be what we call "normal".
