SL900 Spilling Powder

Issue: During every cycle in my brand new SL900, multiple grains of powder (International Clays) spill from the loader when the WAA12 hull descends after being filled with 21 grains. I could accept a slight "leaking" of powder- like I got with my old MEC powder bar/bushing mechanism- but this spilling is doubled in comparison.

Static Electricity?: There is a strong static charge in the clear powder measure tube (13691) that causes powder to adhere to plastic. As suggested in another post, we have inserted two strips of dryer sheet with marginal relief. There is no evidence of static charge beneath 13691, including within the powder dispenser body (22273) so static electricity doesn't seem to be the cause.

I am loading Winchester AA hulls, once-fired. The SL Sizer Collet Sleeve (16742) seems to be sizing the hull correctly, and there's no indication that powder may be collecting on the top of the hull and spilling off of it as the powder-fill stroke returns up.

Also use a dryer sheet to wipe off the inside and outside of the powder funnel that expands the case mouth.

RE: SL900 Spilling Powder

I've noticed a similar "problem" when loading on my SL900...and I'm pretty sure its a static problem but the source of it I believe is bit of a mystery (as is the issue with al static problems). I have a theory however.

On the SL900, the hull is flared and powder is dropped at station 2. The die at station 2 "wipes" the hull as it is extracted and this I believe charges the hull. What I've seen is powder literally jump up the hull when it is extracted from the die (look inside one of your hulls and you'll probably see powder up the sides of the hull).

Some powders seem to be more "problematic" than others. I typically load either Clays, ClayDot or 700X and all of them seem to do it. I've noticed that when the humidity is high (like 60%), I don't have these powder migration issues...when the humidity is low...it becomes much more frequent. The other possible source of the problem could be when the wad is inserted. The air below the wad has to escape around the sides..and that air could contain some flakes of powder...but I doubt thats what your seeing.

How to fix the problem...don't know. Static is a surface charge issue and you can't easily dump the charge. Grounding the reloader won't help. Increasing the humidity as I mentioned seems to help...but we can't control the environment very well.

I've tried the static sheet trick...wiping out the powder hopper with a static sheet...none of it worked for very long; so I just live with it. Its not too bad...I just make a point of taking the vacuum cleaner and doing a quick "one pass" about every 200 rounds when the humidity is low. I'm fortunate that I live in a part of the country that doesn't typically have low humidity problems (Seattle).

If you literally are "spilling" powder, you need to identify where its coming from. I've never seen a "spilling" issue with my SL900...so if you are seeing that, I'd say there is something wrong with yours...however I'm guessing this is a static issue.

RE: SL900 Spilling Powder

Problem is not electricity, broblem is part no 13853 is hollow.
Fill the cavity with epoxy, leave tunnel for adjusting screw.
You can also fill cavity in 13652. This helped me.
Why do they not make these parts solid ?
