Gotcha. I made sure not to adjust the die body as I didnt want to affect the sizing function. Im going to take a look at the threads where the pin attaches to the rod. That would explain the issue. If it was, I'm willing to bet the pressure needed to deform the brass and create the initial problem also damaged those threads. I want to avoid separating the case prep and the loading due to time/life constraints. Maybe one day when I'm retired.

Gotcha. I think I have one of those squirreled away somewhere. Do you have any issues with primers being sucked back into the pocket? I had that issue with the RCBS and Hornady dies on my other press

I thought thats what i was doing when i bought the $250 Lyman die set. I would have bought the dillon dies if they were available. Have you seen how backordered they are and what the secondary market is on Dillon dies? These Lyman dies are supposed to be top-notch and, aside from this odd style for depriming die, appear to be just that.

Yeah, I'm not sure I would have found it if I didnt have the other press set up next to it and attempt to compare station-station. It doesn't much in the way of depth adjustment. Very very little. I added a large o-ring to the cap to create some extra space. Still get good forceful primer ejection without the brass damage.

Thanks again IVC - thats exactly the breakdown i needed and typically how I think. I tore it down and saw how everything interacted but couldnt find anything that looked amiss. What i did find is the Lyman Pro 9MM resizing die may be the source of the problem. The decapping rod is very long and is overinserting through the flash hole. This is deforming and pushing the primer pocket out to prevent a new primer from being fully inserted. This explains why a hand primer cannot insert the primer to below flush either (probably a risky mistake to try in hindsight). I determined the issue when i processed brass on my hornady press and transferred them into station 3. Worked like a charm and had me looking at station 2 pretty intently The decapping rod doesnt appear yo be adjustable like my rcbs or hornady variants; however, I really like the spring. I loosened the cap at the top and took the die out 1/8 turn and that appears to have fixed the issue. I'm about to try a run of 100 cartridges to see.

Snip - that is interesting since my old Hornady did not have a swaging feature and the only brass that caused problems was crimped brass. Im sure the swaging rod can cause its own issues but am still learning how it should be used/adjusted. I tried finding some videos on youtube that explain the feature but not many gave a good idea. What gauge would you recommend? Also, i am loading 9mm and forgot to include that in the initial topic.

I was hesitant with the new machine too. What things are known to affect primer seating depth on the machine? I have checked: 1) shell plate nut 2) rocker bolt 3) set screw in the toolhead. Turning tighter just causes the brass to get forced into the shellplate. Again, a complete teardown of the primer assembly is all i can think of at this point but I'm not fluent enough on the machine. Im going to read the thread midatlantic posted before I do anything on the press thougb

Thanks all for the responses! IVC, coming from other types of presses has me attentive to the depriming and im 100% certain that stacking primers isnt the issue. Im getting positive spent primer ejection and the swaging rod isnt crunching the old primer into the brass. I just double checked all the tabs this morning and they appear good to go though. JMO - i checked that bolt this morning and it was snug. To be sure, i loosened it and resnugged it to see if it was just torqued odd from the factory. No change on the primer depth. Midatlantic - i think thats the next step. Completely disassemble, clean, regrease, and reassemble the primer assembly

I just set up my new RL1100 and attempted to tune each stage for 9mm. I ran about 50 test loads and they looked great. The primers were just below flush. Then, i felt some odd resistance at the bottom of the downstroke and from that point forward all the primers were above flush. The shell plate appears to be tight enough. Any tighter and it will not rotate for indexing. Adjusting the primer depth screw just makes the brass get pushed and wedged into the shell plate. Any ideas for someone new to Dillon gear?

Excellent! Thank you for the replies!

I'm looking to upgrade my current LnL AP and the manual Apex 10 is tied for first place. The big draw is the primer issues i keep seeing everywhere. Has this issue been addressed at Mark VII? Or is it still a plague?

Not to revive a dead topic, but has anyone got the pistol and checked the box?

I want to know if anyone has been successful in modifying their Beretta PX4 Storm to fit the CCP box? I have swapped most of the parts with LTT parts and about to modify some base pads. I would like to be able to use it at Sheepdog this year (or nats if I win the lottery).
