Smutz on my 550B

[rfwobbly]

The base of my 550B, right around the main shaft seems to be covered with all sorts of grit and grime from the decapping process. I clean it weekly, but it reappears. It seems that about 1 in 10 primers don't make it into the flip-down chute and about the same amount of accompanying primer grit. This grit only appears when I reload 9mm Luger. (I'm using both Dillon and Redding dies.) When I reload 223 and 45ACP all the primers seem to fall into the chute just fine.

If it was just trash building up it wouldn't be so bad, but the "smutz" has now started being drawn between the main shaft and the body which is giving it a very rough feel and started to abrade the shaft. I lube the shaft per the instructions.

The primer chute is opening, and I've changed to the solid hinge pin as suggested here. The chute has some notches in the corners which I filled up with epoxy in an effort to close all gaps. No difference. I also varied the height of the decapping pin so as to time the primer's exit. No difference. Apparently the primers are simply hell-bent on shooting out at varying angles.

This bothers me most because I'm a machine design engineer by trade. The spaces around the chute are so tight that there's little room for add-ons. I'm going to mod the chute today with a small piece of beer can to see if I can make the chute into a larger target. Any better ideas?

I took the sleeve that covers the 100 pack of primers and cut it open. I then trimmed it to make a chute to fit into the rear of the spent primer cup and had it extend upward so it is behind the discharge chute. The cardboard is fitted into the spent primer cup so that it extends slightly on each side from the rear of the spent primer cup.

When the discharge chute is brought down it is actually inside the cardboard chute when it opens and drops the spent primer. Takes about half as long as this narrative to make one and it is easily replaceable from materiel readily at had when reloading.

Lots of methods in the Tips and Tricks thread - cleanest way is attached drop tube to container under bench. You do have to remember to empty the jug once in a while - anyone know how many primers it takes to fill 8 pound HS6 jug - I'm on my 3rd dump on the 1050

I was having problems with my primer chute sticking. I'll have to look up those tips and tricks y'all mentioned, especially a solid hinge pin.

I solved the sticking by sanding with 800 thru 1500 grit paper and a bit of high gloss polishing compound. I have thought about a drop tube method, and I'll probably switch to that in the next couple of weeks. thanks for the posts, gives me more ideas...
