Am I the only one who likes the "old school" cast iron presses? I have my Dad's old Herter's Super Model 81 two ram press he bought back in the late 1950's or early 1960's that weighs about 60 pounds. I don't think you could wear that thing out in 1000 years, and I am sure that you could full length resize 50 BMG cases with no problem on it. I also have a couple of Lyman Spar-T turret presses with 6 holes in the turret, so I can keep dies set up for 4 different rifle calibers all the time. I know some people don't like turret presses, but if you keep them adjusted properly I get the same quality ammo and results as a single stage press. I also have 4 of the old Lyman Tru-line Jr. turret presses that are great for reloading for pistol cartridges (I am sure that they would be fine for small rifle calibers like 223 or 243 too). The good thing is that these old presses are available cheap on places like Ebay and estate sales, so after a little bit of cleaning up and tuning you have well made (in America) tools that will last multiple lifetimes. I didn't pay over $40 for any of the Tru-line presses, and not much more than that for the Spar-T presses. I mount each press on its own plate that fits into a "receiver" on my reloading bench, so when I need to change to a different press/caliber, I just slide the one mounted out and pull the press I need from under the bench, slide it in place and lock it down.
Certainly the Rock Chucker and ones like it are great presses, but if you are on a budget don't overlook some of the older presses that can be a good option also.
