njl Posted December 15, 2011 Share Posted December 15, 2011 I've been loading (mostly pistol) on my RL550B for about 3 years now, I think, somewhere between 5k and 10k rounds...so I'm not a total noob...but lately, I've been loading some small primer 45acp using mixed (Win, Federal, Speer) once or more fired brass. I can't remember if I used walnut or corn cob for tumbling this batch, but it was one of those two, with cut up used bounce sheets. Anyway...the two problems are, the powder funnel is really sticking in some of the brass, to the point that the upstroke (until the funnel is released by the brass) is way harder than the downstroke, and I keep having problems with the primer slide not picking up primers because it's not getting full travel. A third issue I just remembered is that every so often, something is binding and not wanting me to quite lower the ram all the way. I know the powder funnel can get stuck in new brass, or brass that's "too clean", but this stuff is neither. I know rubbing the funnel down with a scotchbrite pad can help...and have done that...but it didn't make much difference. I'm starting to wonder if either lubing the funnel or inside case necks is worth trying (or safe to try)? Is there anything else that can be done/tried to reduce the brass getting stuck on the funnel? The primer slide, I'm starting to worry is a lost cause. I've had to take it apart for cleaning every hundred rounds or so lately. I think the problem is that so much crud is released during decapping and gets everywhere, that the bottom front area of the primer slide and the corresponding surface on the primer track bearing have visible pitting that lines up (I assume from decapping residue getting between them), and the pitting is deep enough that a bunch of rubbing by hand with a scotchbrite doesn't smooth them out. Even after these surfaces have been freshly cleaned (wipe down with a paper towel soaked with 90% isopropyl, scotchbrite, then the isopropyl paper towel again), the primer slide doesn't move smoothly. I've heard of people lubing this area with graphite powder (lock lube), and tried that, but I don't think it helped at all. Is there anything else that can be done in this area...or is it time to either use something more aggressive than a scotchbrite pad to really smooth out the surfaces, or bug Dillon support for some replacement parts? The press binding up, I haven't quite figured out. A few times, I've found that it was a spent primer that missed the cup and landed somewhere it shouldn't have on the press (interfering with movement of the primer slide). A few times, it's seemed more like it was the little trap door thing that catches the primers (or doesn't...that problem's been worse recently too), and I wonder if its time to replace the paper clip section I put in there when the original pin bent. Last night, I noticed a couple of times, the trap door wasn't closing on the upstroke...so spent primers would just fall right through.
