So your saying that you have to tune it per given load you want to use?According to the u-tube video's,making a change in the die adjustments can be a problem trying to get a wrench and room to adjust the die's on top,it is probably because the 900Sl,was built on a 650 Dillon frame and things get confined more,this could be
a problem for folks,that reload lots of different shells and need to make changes fairly often [ like me].The roller handle and shell feeder are a plus to this unit.I have a Spolar powerload hydraulic,that I purchased in 1991 and have used it on different ,loaders
and it still runs like a champ,although it is noisier than the newer models,I have often wondered,at times how much my arms and shoulders were save by using this method?
Don't lube the shot. Wash it in a rock tumbler, dry in the sun on a screen, then a little graphite in a shell tumbler. The shot is glued (sticking, dirty) together and bridging in the Dillon.I got the Dillon in and have spent all day trying to get it up and running. every die had to have some adjusting [ not that hard to get to them ] but aggravating still. since they are supposed to be set up for 1 1/8 oz loads with AA hulls and that is what I have . In all fairness to Dillon part of my problems may be the old shot . I will lube it with graphite when I get some . till then I may try to molly coat some of it and see if it drops a consistent shot charge. Powder charge was no problem except the die was smashing the hull and had to be backed out a full round to stop that. I weighed the shot on every round so I could get the pre-crimp and final crimp adjusted correctly. hopefully the graphite or molly coating the shot will help the inconsistent shot charges. Dillon has been helpful but and I am sure I will be calling them in the future . lubing the shot is my last hope
