eBay

First, And this is important.

I have been selling on eBay for over 25 years and have had no Negative or even Neutral reviews. ALWAYS POSITIVE. As this is a custom product designed and produced by me, I offer a 1 year warranty. Any problem send it back for a refund or replacement.

This Spent Primer Cup replaces Dillon P/N 13650 (Spent Primer Cup). This cup is specifically designed for the RL550a and RL550b.

There was a design change on the body of the RL550c in which the diameter of the ram housing was increased. The cups for the RL550a and RL550b won't work on the RL550c.

These cups have improved geometry that better directs de-capped primers into the cup rather than on your floor. If you still drop primers after getting this cup check the little cotter pin on the primer chute. That pin gets beat up and worn and hangs the chute open sometimes.

Or if you want to really one-two punch ever dropping primers again, look up my improved roller assembly and primer chute (eBay Item 196357040074).

I have worked as a Mechanical Designer for over 33 years. I have shot High Power rifle and Smallbore Pistol competitively since 1989 and have owned Dillon RL550 reloading presses since then.

These units were designed by me, FDM 3D printed on a Bambu Lab X1C printer with Blue PLA+ filament. (If you prefer a different color "Black or Red" please message me and allow 2 days to get these into cue and print).
