Jessdigs,
Your charge bar looks very much like my dl 155. If so, you can use the same bushings as Hornady or Ponsness Warren. I will measure the inside diameter of the shot and powder holes in mine and post it for you today. If they are the same and depending on what gauges you plan to reload for, cause that will determine what size shot bushings you need you can get them from whoever has them in stock and or the cheapest. I got #'s 4,5,6,7,8 from Ponsness Warren direct from Idaho, they also fit my DL-155 and my Ponsness Warren model 375. Both of my machines also use the same powder bushings, but since I already had about 35 powder bushing from having four MEC loaders in four different gauges I just went to BPI and got their adapter bushing holder that allows me to use the MEC bushing in both the DL and the PW machines. Now just a heads up for you, when you get started reloading these shot shells, keep in mind that the powder charts are a GUIDE ONLY!!!!!! As an example if the load data call for 18 grains of Alliant Red Dot, and the powder chart tells you it is bushing number 23, the correct way to go about setting up the correct bushing is to start with the number 23 in the bar without any shot loaded yet in your shot hopper, fill up your powder and then cycle the powder seven or eight times into a bowl and then return the powder to the hopper, then drop another load of powder and weigh it, only then do you go up to the next powder bushing if it measures under the specific load data amount. Same with if it is high, then you pull the bushing out and go to the next number down. THE BUSHING CHART IS JUST A GUIDE. You must weigh the powder drops in order to get the correct powder bushing in the setup. If the guide tells you #23 is the one, but your machine with bushing #25 is what gives you the correct amount of powder in grains, that is the one you should use. Also, always keep a static free small diameter cylinder handy, a once fired paper hull with fired primer still in it is handy. There will be times when you want to drop some powder and weigh it while you are loading shells just to check the powder drop weight, having a non static container handy is nice, use it to dump powder into for the weight check and then dump it back into the hopper, you are then going to want to put it back under the drop tube so you can then cycle the shot into the empty paper hull also so you can get the machine back to the starting cycle of having the charge bar over at the powder side of the cycle process. And then of course pour the shot back into the shot hopper and you are ready to resume your loading.
Here is a picture of the powder bushing adapter from BPI. and my plastic organizer for my shot and powder bushing for all my reloaders, MEC, PW and the DL.
