    I'm looking for a high leverage single stage press to fill a variety of tough sizing roles, bullets, brass, etc. It must have the 50 BMG (1-1/2-12) threads available.
    Considering the Redding Ultra Mag press.
    Hornady 50 BMG
    Lee Classic Cast w/ a chater pipe :D. no, really.

    You don't have many choices that can do the .50. I don't have a direct answer to your question, but you should add the Dillon BFR to your list.

    I don't own a 50BMG. I just need single stage leverage. The large format threads are for the LNL bushing adapter.

    and there is a 1-man company in Texas or Arizona who advertises a .50BMG press he makes. It's expensive but looks interesting.

    Based on what you're looking for, the Lee Classic cast single stage will be perfect for your needs. I have one and it's a fine press. Primer disposable through the ram into a long plastic tube into the trash can or a coffee can, safety primer feeding the ram prime on the press and capability to take the LnL bushing conversion kit. Also has capability to adjust the operating handle to best ergonomics for your use. Excellent mechanics and made of steel and cast iron. What's not to like, especially for the price?

    Another option is the RCBS Rock Chucker. But the Lee pushed the Rock Chucker I owned off the bench. It's a better designed press than the RC. Food for thought.

    A Dillon BFR or a Corbin Mega-Mite.

    I love the Lee for all the reasons you listed. In it's current form it just doesn't have the leverage I need. Adding a longer arm to it is one of my options, but I'm afraid I'll get my work too far away from me.
    The Redding Ultramag would have me believe it's got the most power due to it's linkage going all the way to the tool head but I've never used one.

    Single stage only please.

    No doubt the Mega Mite would fill the bill. Unfortunately it is a $1000 press and my budget does not allow. Mebe I gots champagne taste on a beer budget :p

    I would love to hear from Redding Ultramag and H'day .50 press users.

    If you want power find yourself an old western scrounger rock crusher press. It weighed a hundred pounds if i recall correctly and is capable of crushing the presses mentioned in this thread. :eek:

    Anyone ever do a ranking list?

    Wow. At a hundred pounds, you might not even have to mount it on the bench. The weight alone might keep it steady.

    I have heard that the Forster Co-Ax has good leverage. The highest-leverage press I have ever personally used is the RCBS RockChucker.

    Has anyone ever done a comparison that ranks presses by their strength or leverage? I would be interested in knowing where my RC stands in relation to others. Right now, I only know it is stronger than my Lee Classic Turret, and presses I have had in the past (RCBS Jr, Lee Pro-1000, Lee Challenger)

    I just got an old issue of handloaders digest off the shelf and looked the crusher up. It say's that it weighs 80 pounds and is capable of loading 23mm and develops over 20,000 pounds of ram pressure! in 1990 it cost $695.00 for the press, $45.00 for the angle block, shellholders were $30.00 each and a set of can crusher plates were $14.95.

    The CO-AX doesn't have near the leverage the Rockchucker has...

    When i need SERIOUS leverage, i use my RCBS "Big Max" press. It is bushed, has a huge throat and HUGE leverage...

    Found this,
    calculating mechanical advantage of a press, measure the distance of the arc when you cycle the handle the end of the handle divided by the distance the ram moves at the same time ie; 30" divided by 3.5" of ram movement = 8.57 to 1 ratio?

    I think it would be interesting to see or make a chart like Lost Sheep suggested. Otherwise how would you know unless you had them all in a room set up to do the same thing.

    Well remember that these cam over at the top of the stroke so distanced traveled will be less, with the last ? distance. All of this is due to way the linkage is setup.

    20nickels method would be accurate for calculating the average mechanical advantage over the total stroke of the ram. What that neglects to account for is the fact the mechanical advantage is not linear, due to the changing angles in the linkage. Mechanical advantage is the least, early in the stroke, when the ram moves more rapidly relative to the stroke of the handle, and is the greatest late in the stroke, near the point where the linkage cams over, and the ram moves the least per stroke.

    I don't think I explained that very clearly, but if you want an illustration, see how far the ram moves in the first 2 inches of handle movement, and in the last 2 inches, and you will see the difference. In short, the instantaneous mechanical advantage will vary based on what part of the stroke you are in.

    Sorry to nitpick but actually the Lee Classic Cast doesn't fit your requirements. It uses 1.25-12 threads not 1.5-12 threads.

    If you're looking for a 50 BMG press with 50 BMG dies, then the Lee is a good option. Just know that Lee BMG dies only work on the Lee press and the Lee press can only use Lee BMG dies. If you want to use a CH4D neck sizer (for example) then the Lee is out and you'd need something like the RCBS/Hornady.

    If you really want the LNL bushings I'd recommend the Hornady LNL 50 BMG kit.

    I have an old C-H CHampion I bought new about 1970. They will crunch about anything. I got it to reform rifle cases, which it did with almost no effort. It has the larger diameter hole for dies but comes with an insert for regular 7/8 dies.

    Part of the patent on the Rockchucker was the toggle block linkage.

    The mechanical advantage goes through infinity as the block pivots and the lever arm on the short side becomes zero. The arm on one side goes to zero, and when you divide by zero funny things happen.:p

    Before the patent all presses where direct acting, and the leverage depended on the length of the handle and simple fixed ratios of lever arms.

    The size of the press and its ability to resist deforming at high loading is what you really need.

    Corbin csp-2 or hydro with adapter.

    "I don't own a 50BMG. I just need single stage leverage. The large format threads are for the LNL bushing adapter."

    The LnL bushing adapter fits 1.25-12 threads, just like a RCBS Rock Chucker. If you get the 1.5-12 thread press, you will not be able to use the LnL bushings. Which is why I originally suggested the Lee Classic Cast after reading your original post.

    You're right Dave. I didn't realize there were two popular sizes for the 50 dies when I 1st posted.

    Just curious why you need all the leverage?
