the same thing as the lee breechlock?
i think thats kinda silly. then you have to buy bushings for every die.
I do have to use the LNL-bushing on mine.
Did you notice the white spacer on my RCll press, under the bushing?
That is a spacer to raise the Hornady LNL bushing up to be compatible with the LNL-AP press behind it. I can pull a die out of the LNL-AP and put it in the RCll and not have to change the die adjustment. Before I bought the Lee ABLP press for .357 mag, in the far back where you can't see it, I loaded all pistol/revolver loads on the LNL-AP.
I'd fix any rejects on the RCll at the end of the session. With the spacer and bushing, the dies swap out without changing their settings.
This keeps me from having to buy more than one die of each, having to setup the die for a different press, and having to set up the die for one reject round, then have to set it up again when I put it back in the Hornady press.
If I load precision rifle loads I take the bushing and spacer out and put the original RCBS insert back in. My rifle dies are set up for it.
I don't load many rifle loads right now, looking for a new shooting range for rifle that I can afford.
I personally like Hornady's die bushing system. I do not like Lee's, They are to finicky to use and are easy to mess up the threads on them, then the dies tightens up before it supposed to and the dies are now off.
Just starting out you will find a lot of things "questionable" but the more you learn about reloading equipment, the more of it will make sense to you when you see something like this.
