My Lee Perfect Powder Measure leaks some when I use LONGSHOT. Tried tightening the drum with little success. And buying a new measure is not an option at the moment.
Anyone know of a fix for this?

Lee Perfect Powder Measure Leaks?

I haven't tried it, but I've read of quite a few people putting some valve-lapping compound on the "cone" and working it back and forth a couple hundred times to take down the high spots and make the two sides mate better.
Mine leaks some with titegroup and AA #5. I've been going to try lapping it, but haven't had a chance to yet. Most of my loading is with extruded rifle powder and if that was leaking, I'd be in trouble.

Mine leaks a little with some small grain pistol powders too. It seems to be considered "normal" for this piece based on the what I've read. I dont worry about it too much. Just brush it up when finished loading. After 100 rounds it loses maybe one or two grains of powder.
But what does bother me just a little is that with WST, not only does it leak, but kinda binds up the drum making it difficult to turn. WST must be hard or gritty.

Yes, it can be fixed with valve grinding compound.
What I did was to crush up some chromium oxide buffing compound and mix it with a little mineral oil.
I fixed two PPM's this way. But second one was so bad that hand lapping would have taken weeks with my abrasive paste. Chromium oxide buffing bars are very fine. I made a jig with which to turn the part with an electric drill. Maybe you can use something more aggressive.
Both my PPM's will drop hundreds of 223 loads of H335 without any grittiness and without spilling a single drop. That's my second finest powder. Longshot would be no problem, at all. H110 is still too fine for my PPM's, though. It just about works, but then after awhile, the grittiness starts to set in. I think one of them can just about handle it, but I don't want to take the chance of roughing up my measure, so I just use a dipper for H110.
If there is any measure that can drop H110 without grittiness, I would be impressed enough to go out and buy one - even though I'm done with the powder.

I have a Hornady LNL powder measure and I use H110 all the time, for my 300 Back Out.
I've never noticed any gritty or grinding feeling.
I had a RCBS Uniflow a while back, no trouble with it either.
Maybe you need to try one of them.

You can also fit lap the drum and rotor with sand paper. Start coarse and then fine. Mine leaked H380 before the fix. Now Ball-C(2) with not even the smallest grain falls out.

What do you mean fit lap? I ran some graphic lube through mine, but I still have to really tighten the screw with fine powders.

Fit lapping is where you use the profile of the rotor to make a mirror negative drum. Just as you would use valve grinding compound with a good bit of resistance to remove all the high and low spots.
Do not over tighten the through bolt. Snug is good enough if it is fitted properly. All the torque in the world wont help it if it needs to be lapped.

Graphite is always a good idea

I gave up on mine, I bought an RCBS Uniflow, a Lee Pro Auto-Disk & finally a Dillon measure which is mounted on my press.
The 3 I bought all work well with atleast some powders.
Like 2400 doesn't work as well with the dillon, but measures perfectly with the Lee Pro Auto-Disk

I took it apart, took a razor blade to the edge to remove excess plastic, then just threw some lee sizing lube on it. that seemed to work, but after awhile it leaked again. so I will probably try that lapping idea myself.

My powder measure is not leaking now . That said I only used Bullseye and Titegroup. Probably need to wait until I do AA#7 first to really be happy.
What I did was pour graphite into my powder dispenser, loosened the screw on the side to make sure I got leakage. Ran the graphite through with the leakage, then tightened a little so I'd still get leakage, but just a little bit. Ran that through, tightened tighter and ran some graphite through. Had to double tap a number of times to get all the graphite out. It wouldn't all come out otherwise. Now I can turn the handle and it's smooth, not hard to turn and I have no leakage.
