Primer Swage Adapter for a 550?

Hi.

I was out in the garage puttering and looking at some old Dillon manuals. I was wondering if anyone had ever given any thought to adapting a 550 to swage primer pockets? The thought crossed my mind about replacing the primer cup assembly with a swager pin and then putting a piece of threaded stock in the die station to bottom out in the die. Sort of the way the 1050 operates. A person could then set one toolhead up for processing cases and then switch out for the actual loading. I am no machinist and therefore won't be trying this myself but wondered if anyone has considered it or made such an arrangement.

Regards,

Bob

Thought about it a little more and remembered the 550 primes on the upstroke and the 1050 on the down. Duh!

I had the same thought. Since I use military brass, I always have to tumble, de-prime/resize and then use the 600 to swage the primer pocket of each round before I can actually start loading. That's a lot of handling and takes a lot of time. If the primer anvil assembly could be replaced with a mini swaging rod, wouldn't  the 550 have the ability to effectively swage the primer pockets on the down-swing of the handle? I realize it would still involve running the brass through twice, but it might be easier overall than the way I'm doing it now. Again, I'm not a machinist, but the swaging adapters, both small and large could be made for pennies apiece, and give the 550 owner an option to the 600 swager. My biggest reason is that I'm going to start making 300 BLK brass and it wold be PERFECT to de-prime, size, and swage in station 1, and trim in station 3 with the trim die and 1200 power trimmer. What do you think??

if you have crimped cases you have to size deprime them before you can swedge the primer pocket, so just make a primer bar with a swedge and you can swedge on the down stroke cutting out a step on the brass prep

We don't offer a swager for the 550 and 750 machines because the case is not supported from the inside. The amount of pressure needed to swage a primer pocket can damage either the case rim or the shellplate. Use of aftermarket swagers voids the warranty.
