I bought 2 Dillon XL750s a while back and am just still getting started with the Blue process ... first time on a progressive, but have a number of years of general experience with my Lee Challenger and RCBS Rock Chucker single stage presses with pistol and rifle reloading.

However, not only first time on a progressive, also first time with crimped primers. I have a Dillon Super Swage 600 to swage the primer pockets, and checking them with a go no-go gauge tells me their swaging properly (my assumption, as the go gauge fits fully into the primer pocket with a little tension, and the no-go gauge does not go in at all).

I have a significant batch (for me, at least) of about 5,000 5.56 once-fired military brass (~ 90% crimped primer) and 5,000 9mm once-fired military (~75% crimped primer, maybe?).

The 5.56 seems to seat the primer with somewhat of a "crunch" feeling 50-75% of the time, and the 9mm maybe 20% of the time. Attached photo showing the results of mangled or too high seating on 2 or 3 out of each 100.

Second issue or observation is that I was getting a fair number of no primer feed, to the point that I was watching the primer arm coming back empty and going forward with a correctly oriented primer. A few were tipped, some were not feeding at all. This really slows down the production, and makes a nice mess of spilled powder cleanup, with then further exacerbates the primer pickup, I think.

Thoughts, ideas, suggestions, other favorite discussion forums for Dillon gear specifically?

Thanks!
Greg

Call Dillon. They have great tech support and can offer solutions.

That said, it sounds like you need to swage the pockets a little more.
