Product Information

The "O" frame press by design is the strongest and by far the most popular style press. The larger than average 4" opening allows for maximum hand clearance. The spent primer catcher is positive and allows you to route the spent primers directly to the trash can. Priming is a dream with the Lee Lever Prime System. Best of all, it includes the Breech Lock Quick Change die system. Change dies instantly with a twist of the wrist, and you never have to re-adjust your die.

Other features include all steel linkage with adjustable length lever. This same press costs you over twice as much from other manufacturers, and that's without all of the Challenger's features. Press includes one Breech Lock quick change bushing.

Frame is cast out of aluminum.

Good value

By Brian L. on Jul 22, 2023
I had an earlier version of this in the mid 90's. It worked well. I'm glad this press has been updated to include a used primer collection tube. I do like the Breech Lock feature as well.

Redesigned challenger press.

By Dave S. on Jun 05, 2020
This press corrected the issue of the pot metal linkage that my original challenger press had. Lee stands behind their products and that ssue was resolved. Still going strong after 25 years of reloading. I like the Bushing setup but, I think I'll leave it in place and change out my dies by hand. I'd rather thread my dies on steel than aluminum. I highly recommend this basic press.

Excellent Entry Level Press

By Raymond K. on Dec 09, 2019
I have done moderate case forming (30 Herrett, 35 Rem Rimmed), sized large rifle cases in the 30-06 class with no problem.(Imperial Die Wax) This press is packed with features for a unit at this price. Compact design, the Breech lock bushing system, primer disposal, priming system. A tremendous value for the money. Just keep the ram lubed (STP or Lucas Engine Assembly Lube) and don't abuse it and it should last for many years. Totally outclasses the RCBS Partner for less money.

Very Good value for the money.Would reccomend

All the single stage press you need

By Paul H. on Jun 30, 2017
I've been using this press with Lee's dies and breech lock bushings for years now, with both rifle and handgun, and it has never let me down. You can pay more, but you don't need or have to. Nothing wrong with the green or blue guys, but Lee makes reliable, accurate reloading gear. Rounds made with this press have let me shoot dime-sized groups out of my Howa .223 at 100 yds. Highly recommended!

Very Good Press

By Eric S. on Jun 25, 2012
I have loaded at least two thousands rounds of rifle and pistol ammo with this press so far in the last few years. Very well built. Keep it clean & lubed, it should last a life time.
