Starting to get worried
« on: February 07, 2012, 12:33:44 AM »
So I have been reloading for several years now and have shot 500-600 home brewed rounds through my little PM9.  Only hiccups have been some weak loads that I made at first, erring on the side of caution, that would not lock the slide open on last round.  I have since revised my load a bit, still under minimum load for 9mm.  I have used Rainer 115gr fmj (500) and Hornady 115gr JHP(100) with my current powder charge of about 4.1-4.2 grains of Unique.  This is under the Lee manual of 4.5grs minimum with a COAL of 1.120".  I was confused because the autodisk powder measure to equal this was .46 i think.  After 100 rd batch of this, I upped the charge using the .57 autodisk measure, but I weighed the charge at 4.1-4.2grs.  These have been flawless in my PM9.  I am worried because I just put money down on my first Glock (G19) and have been reading a lot about Glock KBs.  Most have been attributed to .40S&W and overcharged cases combined with an unsupported chamber, but two I saw were with 9mm models.  I know the safe thing to do is to only use Factory ammo, but I still want to reload.  Should I be worried about continuing to use my current load of 4.2 gr Unique under a 115gr Rainer FMJ with WSP primers?  Also, I need to call Lee about this, but why does the recommended starting autodisk measure of .46(IIRC) throw less than the starting recommended load of 4.5grs.  I checked my press, there is no powder getting stuck anywhere, it all goes into the case.  I am very anal about my reloading, no distractions, I check for correct OAL every ten rounds, and occasionally will weigh a powder charge as I go, to ensure it is correct.  Please help to put my mind at ease.  Thanks

So you're concerned about what, exactly? You're loading below the minimum, and still concerned it's going to Kaboom in a Glock? Don't worry about that. I've got some really light reloads that won't even cycle my G17, much less blow it up.

As far as calling Lee about the AutoDisk, I wouldn't bother. That's the worst charging system out there, imho. I have one and it's impossible to adjust precisely, and it's not very consistent in my experience, hence why I don't like it. It's very sensitive to the level of the powder in the hopper. I don't have a better alternative for you other than individually charging each case, or buying a better press. My Lee Classic turret is pretty much limited to single-stage duty these days. My Dillon 650, OTOH, meters powder very nicely.

Nukehayes, you'll be fine.  Just stay inside the charge weights listed in the manuals.  Note I said the plural version of the word.  You should have at least 2 manuals to cross reference data in.  And-

I VERY HIGHLY recommend a book titled "The ABC's of Reloading" for all of us who reload.  Especially those that are new to the pursuit and find themselves without a mentor.

I second what Outbreak said about the Lee powder measure. Thats the one I started with, and if it weren't for the fact that I can't throw anything away, I'd have tossed it long ago. It's imprecise and inconsistent - the disks just aren't a well-designed system. I essentially use my Lee Turret press as pretty much a single stage. I switched over to the RCBS Little Dandy powder measure, and it works ok, except you have to buy a different attachment for each different load. So I actually just got a RCBS Uniflow measure and I'm getting ready to mount it to my bench. I'll let you know how well it works.

You'll like it.  It's a high quality piece. Just make sure you settle flake powders before loading, adding a powder baffle will help.

Norse, I set up and used the Uniflow today for 150 rounds. It's been throwing charges pretty consistently. I hate to admit that I made the stupid mistake of removing the plunger/measuring screw (whatever it's called) while the canister was full ... it didn't stay full for very long!   :facepalm

I'll probably get a baffle for it later, but it seems to be doing ok for now, I'm just making a point to keep the tube full. They also sell a screw for it that's better marked and easier to read, I'll probably get that sooner rather than later as the one that comes with it is impossible to read for future reference. But since right now I'm only doing one load, it's not essential as I won't be changing the amount I pour very often. But once I start doing other loads I'll definitely spend the $5 or whatever it is for the better adjustment screw.

Nuke, back to your original post - like I posted earlier, toss the Lee disk measure. And if/when you upgrade I can't recommend the RCBS Uniflow measure strong enough.

As an aside, I'm learning that the more time I spend reloading, the more equipment/accessories I'm gonna have boxed up that I've upgraded from.

Read for future reference?  I never pay attention to the little marks on the shaft.

I toss the first couple of charges back into the hopper, then weigh the third.  Adjust the screw up, down or sideways as necessary.  Repeat till it's throwing the weight I'm looking for.  Lock it down.  Re-check to make sure it didn't move while I was locking it.  Check every 10th charge.  It never moves unless the lock-screw comes loose.

And the baffle helps a lot on the consistency, especially on flake powders.  Keeps a constant weight of powder above the charge chamber, regardless of how full the hopper is (assuming the powder level is still above the baffle).

have been reading a lot about Glock KBs

Most of that is bulls___. Most people don't understand the first thing about the "unsupported chamber" bs.

Reloading for a Glock isn't really any that much different than reloading for other firearms. Inspect your cases before you load and discard the bad ones. Use caution when using lead bullets in the factory polygonal rifled barrel because lead can build up (so clean it more often when shooting such loads or use jacketed rounds).

I don't THINK I'll ever have to face down routers in the streets.

I should hope not. Mobs of rogue woodworking tools would suck to repel.
