H110 powder leaking on my 550B powder measure?
Quote from jborg33661@aol.com on October 2, 2025, 6:59 pmHi guys,
I just loaded up some .300BO rounds using H110 powder. I was noticing that when I lowered the case on the downstroke sometimes I would get a speck or two of powder leaking on the shellplate and I had to clean up the shellplate of leaked H110 powder a good bit after my reloading session of 150 rounds. I also noticed that powder bar was pretty stiff going back and forth in the powder measure when I just checked it with my pushing it with my hand back and forth.
Any ideas or experience in fixing these issues?
Thanks!

Quote from The Human Manual on October 7, 2025, 6:35 pmThere are a few powders out there whose granule size tolerances overlap our powder measure tolerances. This causes the powder bar to stick and bind sometimes. If you are using the small powder bar we can send you a slightly thicker spacer bar to help alleviate this. Powder on the shellplate is more of a static issue. For this, cut a 1" wide strip lengthwise from a dryer anti-static sheet. Dump the powder out of the measure. insert the strip on the inside of the hopper tube until it contacts the metal base. Fold the excess over the top and tape it in place on the outside of the hopper. Pour the powder back in. This will remove the static.
Fine grain ball powders including H-110, Win 296, Accurate 5,7 & 9 can all do this.

That would be great if you could send me a slightly thicker spacer bar for the small powder bar to help with this issue, that would be much appreciated!

Gary, what I did was use some Gorilla brand clear shipping tape on the top of the spacer bar. It is an extra thick tape and exceptionally sticky. That seemed to close the gap and less of the H-110, W296 and others is allowed to escape or bind the bar from travel. Next time I'm in Scottsdale, I'll stop at the Dillon HQ and see about picking up the thicker spacer. I didn't realize that was an option. Thanks.
