Primer fit
I prepped 1500 pieces of 223 brass for match shoot in and AR. I use amy new Dillon primer picket swager. All of the primer pockets feels loose. I checked:

Winchester brass 0.172"
LC brass 0.172"
The brass I prepped 0.174"
The primer swager tip 0.174"
The primers I am using 0.175"

I can seat them 90% with my thumb, no tool.

Dillion Tech support says it is fine. I say BS. This is a semi auto. I can not have loose primers in competition.

I fear I have ruined my entire stock of irreplaceable once fired brass.

Opinions?

Test fire them and see.

push them to the bottom of the pocket.

if you can use .002 neck tension on a bullet and slam/stop it in your AR I bet .001 primer tension is way more than adequate.

I've had good results with my Dillon pocket swager.


Never mistake motion for action.

I was offered a suggestion from a person who also shoots hi power. I tried to push out the primer with a decapping rod using hand pressure. The primer fell out easily.

I can not have primers jamming up my rifle or gas cutting my bolt face. The brass is all scrap. Done.

I was gifted a quantity of brass to meet my needs.

I modified the primer swage. Some time with a diamond lap and my lathe fixed it. I modified the swage tip to make a SAAMI spec primer pocket. It works great now. I am absolutely stunned that Dillon deliberately makes a tool that that is not suitable for the intended purpose.

My bad for not checking the pockets earlier in the reloading session.

Added: I checked the large swage for the tool. The diameter and shape is correct. I suspect the small one was defective as shipped.
