5.56/.223 primer problems

Reloading 5.56/223 and having primer problems.  Every 3rd or 4th case is hard to seat.  The primer may not seat completely, seated at an angle, a flat spot, or partially with a burr sticking out.  Everything looks right, need ideas?

My guess is that you got some military/crimped primer pockets. There's lots out there these days that look fine but just don't cycle properly. I've made it a habit to "process" all my 223. I tumble, then lube. I have a tool head that just deprimes and sizes. Truthfully, I block off the primer seating and leave the rest of the dies out, and let it go to the end. From here I trim if necessary and swage the pocket. It then goes back in the hopper and goes thru the stations like normal. (a different tool head with all the dies) This cuts way down on hiccups during the loading. After loading, they go back in a tumbler (with no rouge polish) for about 15 minutes to remove the lube . This works for me, but I'm sure you'll get lots of thoughts on how others do it.

Enjoy, jj

Im with dive on that. Also make sure your press is mounted solid. If you have a lot of jar you could be flipping primers. Operate your press at a steady rate. You wouldn't believe it but you can run your press too slow. Check what brand of brass you have. Look for the military crimp. The brass doesn't have to have military markings likeLC 5.56 and such. One of the hardest crimps I have come across is PMC. Some Federals will be crimped. Drop the cash if you can and invest in the Dillon primer pocket swager. Hand reaming takes for ever and in the end half your brass will be useless cause you got tired and took too much out. Loose primer pockets=trash. Hope this helps you out.

I was having the same problem as well. First, make sure you have the proper Rev B Seater Assembly (page 52 of the 650 Manual. Having the small seater in while putting inserting large primers is not a good idea. Check your rotary Primer Disc as well.

I'll add my input as well.

I realized the problem for me was the primer pocket on some of the old military type brass. I purchased the Dillon Super Swage 600 Stock Number: 20095 and that solved the problem. I have and have used the 5 station case preparation device but the Super Swage is quicker and I think with more uniform results. Since I don't sort my "range" loads by manufacturer, I just clean them then put them into the XL650. When I get a case that I can tell is not going to let the primer go in, I remove the case, Swage it, and put it back in station #2 on my 650 and it works fine.

Hopefully this will help.

I run a separate tool head to deprime/size, & trim, then tumble off the lube. Before I load any, every piece of brass gets run through the Super Swage, regardless of head stamp. After that priming is an ease. Well worth the time.
