Question: what is the lee lever primer system ? does it work off the press ?
Document: I purchased the Lee Precision Breach Lock press as a standalone to de-prime both pistol and military rifle brass with the Lee Universal de-primer die so as not to work the brass before cleaning/swaging/trimming. I received it yesterday and had it mounted and setup in about 30 minutes. I was able to cycle 500 rds of S&W 40 cal, 200 rds of 5.56 NATO and 50 rds of 30-06 through in a matter of minutes.
I'm glad I purchased this press over the others. I purchased a couple of extra Breech lock collars and it works great. What can I say Lee products work well and are fairly priced. I have set up my dies and changing them takes seconds. No adjustments to the dies, and no problems.I definitely suggest this to any beginning re-loader
Sometimes simple is better - Using the Breech Locks makes for a simple swap of dies. This has become my primary reloading press.It's well make, easy to set your dies up, and use them later. The action is smooth, and the primer tube is nice to have.The only thing I'd recommend was to buy a Breech Lock adapter for each of the dies you may use/own.
For a single stage reloading press, I'm not sure you could do much better than this. It's well built, highly affordable, and looks good too. It comes with priming arms for large and small primers and a primer pickup tube for when you deprime your brass. The arm is adjustable to either side and adjustable for length. The half-turn &#34;breech lock quick change&#34; is nice - set your dies and then leave them.
There's certainly nothing fundamentally wrong with the Challenger Breech Lock Press that I can see - it works as advertised and the breech lock system is really quite clever - but it's not a press that exudes quality. The only real issue I have with the press is that it spits primers all over the place during de-capping, as opposed to dropping them neatly into the pan and down the drop tube as intended.
I am constantly enamored with this press. It's just a downright awesome tool, especially for the price! Lee makes a great working product!
This one works and keeps everything simple and has great power in mounting solutions.Lee did this press right... with Collet dies... you have match grade equipment.
Pros:  once you set a die....  pull it out... put it back in ... return to exact zero  ... thousands of an inch at mostCons:  None, I wish Lee had this press 10yrs ago...
I know you can use a slew of other manufacturer's dies on this press, too.It doesn't come with mounting hardware, so you'll need to provide your own. It does have screw mounts on the top for using the Lee quick-prime device, which is an awesome addition.All in all, I am very happy and look forward to reloading countless more rounds with this tool.
The lee precision breech lock challenger is all I use any more. With the breach lock bushings also from lee quick changes are very easy. Just set your die in the bushing and then install into the press. Great for slowing you down to force you to pay attention. I get sidetracked when using a progressive. This makes you pay attention to detail. Very important when reloading.
