Powder Swelling????

Hello Rick, thanks for the further explaination.

FWIW, I don't load ball powders. Mostly I'm an Alliant & IMR guy, and yeah, there's been a couple of times that I've reduced the (weighed) charge of one of my most-used loads from 8.0 of Unique to 7.8 because experience told me that for some reason, the resulting recoil I was feeling with my "tried 'n true" load was more than it should be. Same canister of powder, same bullet, same primers, same cases, same gun. Only difference was that it had been several months since I'd done any loading.
Untill now, I never quite knew what to make of that.....Thanks !

Kinda makes me wish I had me one of them cronygraphs.:wink: .

May I ask why not a Lee powder measure?

Hi,

I'll try to get the ball rolling, Monty, and I'm sure there will be plenty more comments!

Lee makes three major types of measures I'm familiar with: the dippers, their "Perfect" measure that works like most of the measures that have been around forever (eg RCBS Uniflow, Hornady Lock-N-Load, Lyman 55 and many others), and their Auto Disk.

Each has its good points, each bad ones, which means they're just like every other piece of loading equipment on the market! And to add to that, everybody tends to develop preferences for brands, types of equipment, etc. Most of us have to live within budgets, too!

The dippers are just little measuring cup devices. They're "fixed" measures which means there are a series of them in different sizes to give different charge weights. They're easy to use, and, in the right hands w/ the right powders, CAN be quite accurate. However, they take a bit of practice to develop a good technique, and being non-adjustable, may not give you the exact charge you want. I keep a set, as do many loaders, to "work up" loads on the scale instead of dinking around resetting my other measures.

The "Perfect" measure is infinitely adjustable as there's a micrometer type device to change the volume of a cavity inside a rotating drum. Push the handle up, the cavity opens under a hopper and powder flows in, pull the handle down, the drum rotates until the cavity drops the powder out the drop tube. The adjustability is a plus, but the type of powder being used, and the size of the charge, together w/ technique, can and do affect the final charge weights. I have one of these, also, and it's dead nuts on and boring w/ ball powders, pretty good w/ medium to larger charges of stick powders, but all over the chart w/ SOME flake powders, at least smaller charges. Before blaming Lee for a bad product, there's an RCBS Uniflow sitting right next to it, and it, too, has its preferences!

The Auto Disk measure is another hopper fed device, but instead of the micrometer style adjustable cavity, it uses "disks" that are "fixed" volume cavities like the dippers. RCBS uses the same approach w/ their Little Dandy, and most shotshell loaders use charge bushings that work the same way. The same "problem" occurs of sometimes not being able to get the "exact" charge one wants w/ those types of systems. Lee also has a micrometer style adjustable device one can purchase as an option to counter this problem. It seems to be a "love-hate" solution: as many people seem to love 'em as hate 'em in my limited experience!

There's nothing wrong w/ the Lee equipment as long as one recognizes its limitations. Lee started out decades ago introducing people to reloading "on the cheap" as opposed to the somewhat costly approach using equipment from other mfrs. Some of their equipment is still built to do the same thing: get people loading, don't empty their wallets, and last "long enough" before needing to be replaced or upgraded. So a lot of this stuff is fine for the beginner or the fellow who's not going to load much.

For the fellow who's going to be loading a "lot," there are more durable, and, of course costly, alternatives. For example, a Lee "Perfect" measure may cost one $30, and, from personal experience, I know mine's still doing fine after 12k or so rounds though it does feel a bit flimsy. Will it still be doing so when it's closer to 40 yrs old like its rock solid, heavy neighbor on the bench, the Uniflow? I dunno. I do know a new Uniflow will run you another $50 to find out!

The "good" thing about Lee equipment, particularly for the beginner/casual loader, is when you put the bullet on paper, it seldom knows if the round was loaded on Lee, RCBS, Hornady, Lyman or whatever kind of equipment.

The "bad" thing about it is if you start off w/ Lee, then "graduate" to more expensive equipment if you turn into a "high volume" shooter, or start doing more heavy duty loading tasks--which WILL stress SOME of the Lee products, though not all--perhaps you'll think your initial "investment" was wasted. I don't think so, but many do.

Of course, a lot of these same guys who complain they "wasted" $30 on a powder measure won't think anything of putting $100 worth of gas in their $45k pickup just to "haul" a couple of guns to the range, which is easily accessible in a Honda Civic for $25 worth of fuel... or dropping another $100 when they get back home to keep Mama happy so she'll give 'em a kitchen pass to go shooting again next weekend!

One's priorities can play a big role!

Rick -

A wonderful explanation put in a useful context.

Thank you.

I'll probably consider the Uniflow for my "starter", if only because I detest buying the same tool twice.

My LGS stocks them (about $80.00, I believe), and the stand adds another $40.00 or so. (I like to support the LGS).

One of my recent range acquaintances who reloads for pistols and benchrest shooting has his Uniflow (used for the benchrest reloading) mounted on a small, heavy, flat plate (from the scrapyard), so that he can slide it around to the location on his bench which is most convenient, depending on the type of reloading chore.

Thanks again -

Hi,

If you start w/ the Uniflow, Monty, I don't think you'll ever regret it! Couple of thoughts on it:

In the "olden days" when mine was new, the Uniflow came w/ a small plate for mounting w/o using the dedicated stand. If it still does, that's a good thing. Mine's screwed onto a wooden base so that I can move it around on the bench, and clamp it down w/ a C-clamp. (The Lee Perfect measure's screwed to the other end.)

That plate had a hole in both ends. One you used for the measure, the other could be used to mount on your press, held down by a die. Or, since the measure's threaded w/ standard 7/8" x14 threads, it can also be mounted directly onto a spare press.

If you like that idea, Lee has an answer for you! Their little "Reloader" press is a tiny bit less expensive than the RCBS stand, about the same size, AND you'll find there's ALWAYS a job where an extra press is handy to have, such as mounting a deprime only die (handy if you want to clean/polish/tumble brass before actually resizing it.) I'm pretty sure a LOT of those Reloader presses are being used as stands... they're one of the "lesser quality" items from Lee, and are easy enough to break. Mr. Lee even tells you how to break one in his book, but they still work fine as stands if broken. ;)

Hint: if you watch Midway and some other vendors, in the past they've sometimes had a "package deal" that includes Lee's "Modern Reloading" book w/ a Reloader press for almost nothing more than the book alone. So it's almost like getting a free press, and one can never have too many books on this subject! Doesn't look like that offer's good right now, but the press is all of $28 alone... http://www.midwayusa.com/find?userSearchQuery=lee+reloader+press

Then there's another way to drop about $45 that should prove to be money well spent over the next few years: the RCBS micrometer adjuster that replaces the screw adjuster installed at the factory. http://www.midwayusa.com/Product/654966/rcbs-uniflow-powder-measure-micrometer-adjustment-screw-large-685-diameter

The "problem" w/ the factory screw is it's not calibrated in any way that makes it easy to "reset" a particular charge. The micrometer makes it easy! Just make sure you get the right size for your drum: the factory usually ships the measure w/ a "large" drum so you can throw heavier charges, and sells an optional "small" drum for smaller (mostly pistol) charges. The adjuster diameters differ between them, so you need to match drum to adjuster.

Good luck!

There really is so many ways to go and until you get some experience you'll never know what things are going to be important to you.
For instance if you use Lee dies and a Lee Auto Disc measure, the measure mounts to the top of the neck sizing and belling die, then auto-dumps the powder thru the die when you operate the press. Saves a seperate step if you use a single stage or turret press..
If your handgun enthusiast and shoot more than once a month or so you WILL end up buying a progressive eventually.

Rick, you are a fount of (as yet) untapped knowledge!

Thanks for sharing your experience - the micrometer suggestion is a good one.

I just purchased Richard Lee's book, and I'll see if the small plate is still included for the Uniflow.

I believe that the small drum set-up will be for me at this point - .38 Spl. and .44 Spl. to start.

I apologize if I've sidetracked this thread, and I hope that this is helpful to the original poster as well -

Best to all -

Rick, your post (Tue Jun 12, 2012 11:52 pm) is an insightful essay. Thanks for the excellent writing.

One thing I must correct, though. The Lee Dippers (and many others, too) are adjustable. You can stuff the bottom with a spitwad, hard wax, styrofoam or cardboard disks (shims), wood glue, chewing gum, etc. Some materials are easier to work with than others.

You can also put a hole in the bottom and insert an appropriately sized machine screw which you can then adjust up and down.

Or you can trim off the mouth with a knife, file, chamfer tool or grinder.

Hi,

There's a TON of knowledge here, Monty, but, truth be told, compared to a lot of the guys here, I'm just a piker!

For example, Lost Sheep brings up a good point (which I'd completely forgotten :oops:) about "adjusting" fixed measures, such as the Lee dippers. We used to do something similar w/ shotgun bushings and nail polish, and I'm sure other methods are employed!

Only caveat I'd offer about doing that is to make sure the bubble gum's sticky enough that whatever one sticks in there to do the adjusting doesn't fall out in use! Of course, that's where checking your charges visually, and occasionally w/ the scale, is SO important.

That's one of the joys of handloading: there are usually several ways to do most operations, and most all of 'em work. So don't be afraid to try several to find which ones you like best.
