Lee Pro1000 press ... I spill more power than what I see leaking

Set/hold the bullet over the case mouth as powder charged case reaches Station #3 and no more spilled powder (And bullet is going there anyways).

And make a cover over the primer chute opening (simple paper or clear plastic) and you can prevent powder granules from falling into the chute opening for more reliable primer sliding into Station #2 - https://www.thehighroad.org/index.php?threads/lee-pro-1000.862319/#post-11364696

Thanks LiveLife, on my Pro1000 I am actually placing the bullet on at station 2 before it starts to rotate. My bad holdover habit from SS. is that I am probably check weighing powder charges much more than is needed, so I am too frequently taking cases in and out. I really see very little loose powder either on my press or bench top.

If you are using Pro Auto Disk on Pro 1000 with properly lubricated powder hopper wiper surface (I use fine graphite powder or shaved No. 2 pencil lead rubbed on paper and coat wiper surface until black), PAD will drop most small granule/flake powders with around .1 gr variance (Less than .05 gr for Sport Pistol) due to fixed volumetric disk holes and constant checking of powder drop weights is not necessary.

Only thing I do when I pour powder into the hopper is tap the plastic hopper 10 times to better settle the powder and drop several charges until the charge weight becomes consistent.

When I am using C-H 502, Dillon and Redding powder measures, I will do Quality Control checks of powder drop weight regularly but when I am using Lee PAD on Pro 1000/4000 (ABLP), once I verify initially that drop charge weights are consistent, I won't check again for the duration of 500-1000+ round reloading session.

See that's my downfall. I am still habitually checking about every 20-25th one. Sorry but I cannot help myself. It is not because I do not have confidence in the tool. It is a Force of Habit. And I can't break it. Geesh it took me 20+ years to quit smoking.

So, in all the years you have used the Pro Auto Disk, have you seen drifting of powder charges?

After 600,000 rounds of pistol rounds reloaded primarily using PAD (I load rifle cartridges on single stage with C-H 502 powder measure), I have not seen drifting of powder charges because IT CANNOT DRIFT by design of fixed volumetric disk holes unless two hopper mount nuts get loose ...

So once PAD drops consistent, unless you let the powder in the hopper get seriously low (I usually refill when 1/3 full), it will keep dropping consistent charges regardless whether after 500 cycles or 1,000 cycles or 5,000 cycles as service life of properly lubricated hopper wiper is very long.

There is no need to check powder drop weight from PAD every 20-25 cycles.

Like many fast powders, Tightgroup is too fast burning to provide the proper impulse needed for your pistol to cycle.

I'll take issue with that.
Titegroup is a very popular powder for 9mm and 45 auto. I used it for many years in my autos with excellent results.
W231 is a far better choice, but there's no reason Titegroup won't cycle a 9mm when loaded properly. He just didn't put enough in there.

At 4.3 grs being the max charge per Hodgdon, and at the published burn rate, 4 grs should be enough to cycle the slide, I would think TG would be less finicky than that. Unique and W231 did/does not present that characteristic in my applications, thus the reason for so many powder choices.

You'll be pleased with W231, great powder for 9mm.
Loaded some 9mm with 124 grain plated HBFP and 4.2 grains W231 this morning.

Don't be surprised if it takes an extra few tenths of powder to cycle your gun with plated bullets. It always does for me.

Been using tightgroup for over 2 years try 4.2 grains with your bullet weight.I’m running blue bullets at that weight with no problems and great accuracy.We have. 5 shooters in the family shooting steel match’s with this load and 5 different guns.

115gr PRN from RMR, 4:0 grs, 1.1 OAL

I have been using 5.6 gr. WSF with 115 gr plated bullets for about 20 years. Velocity is about 1160 fps from a Glock 19.
