And here's my solution to the "Spent Primer Scattering Syndrome" on the Dillon XL650.
Materials: 1" wide brass shim stock, .03" to .06" thick; one fired .30-30 cartridge case (I'm sure a .308 or similar case would work fine, too); a few feet of 1/2" OD x 3/8" ID clear vinyl tubing; about 5" of 12-14ga wire; a can, bottle, bucket, or other receptacle of your choice to catch the primers.
Since my press is on a Strong Mount, I had to drill a 1" hole in the bench to run the tube thru. This hole is directly below, and slightly behind, the hole in the press where the spent primers drop thru. If your press is mounted directly to your bench, that's not necessary, but if your bench is really thick, you may have to cut a relief in it so the tube doesn't get pinched.
First, remove the spent primer catcher and its bracket. Use the bracket as a template to mark mounting hole locations on the brass. After cutting the brass to a convenient length - just a bit longer than the distance between the two holes - and rounding off the corners, mount it in place of the bracket. Remove the 650 shellholder plate and use a sharp scribe to mark the brass plate where the spent primer hole goes down thru the body of the press. Remove the brass piece and drill a .3594" (23/64") hole in it, centered on the scribed mark. Sand both faces flat to remove any burrs around the hole.
Cut about 1/4" off of the base of a .30-30 case, sand it flat, center it on the hole, and solder it to the brass piece. Use a small round file to clean up the inside of the hole where it meets the case, sand the brass face flat, and reattach it to the press.
Loosen up the front right mounting bolt and wrap the wire around it, between the washer and the strong mount, make a loop and run the other end loosely around the same bolt. Running the tube thru this wire loop helps to keep the tube from kinking.
The only thing left to do is to run the tube up from your primer catch container (mine is a slightly rusty 30 cal ammo can - I imagine it'll hold about 50,000 spent primers before I have to empty it) - thru the hole in the bench, thru the wire loop, and onto the .30-30 case. The fit on the case is sufficiently tight that no clamp is required. When you trim the tube to the length you need, be sure to allow enough excess for the press stroke.
