Flip it on its side and you can have the bullets drop onto a chute. The ram picks up the bottom bullet and shoves it into the die while the rest sit on top in a magazine.
Like in this video:...

My math puts the bolt thrust at 10500 lbs and the hoop stresses at 140 kpsi. Way past "bad idea" territory and into "I already called an ambulance" territory.

I'd be more worried about the torque than the speed. How big is the motor driving it?
It looks like the perfect candidate to hook up a vibratory feeder to, for automated canneluring. Or even...

Even better than using 5C collets would be to use 3MT collets directly in the spindle, to avoid any runout in the adapter.

Make the press able to take something like 1 1/2" threads, then make bushings for 7/8x14 and 5/8x24 dies.

Hollowpoint, one thing you could try is to buy a set of hardness testing files and use them on the parts you want to replace. That would give you a rough idea of whether a softer metal like 1018...

M-Tecs, if you don't mind answering, how much did it cost to have the ammo tested? I've been meaning to have some tested as well, but it's on my roundtoit shelf.

Make sure your receiver can handle the thrust of whatever cartridge the insert is chambered in.

I don't have any jacketed bullets on hand to compare with, but the lead bullets came out at .224".

I recieved a lead bullet in with my die from Corbin as well, but I've tried making lead bullets for PC'ing and they ended up looking like a SWC like Hickory describes. I think the meplat was .150" on...

If you live anywhere near College Park, Maryland you might be able to find them at the National Archives. The only problem is that there really isn't any way for you to find out which record it would...

With a rotary indexer that has a fixed die on it that the bullets are pressed into. Corbins has one: http://www.bulletswage.com/pcm-2.htm

You could try to find a picture of the round taken head on and calibrating the image based on known dimensions (rim diameter) to double check the bore diameter. I'm not sure if Inventor has a...

One problem I can see is using the papers with small caliber cartridges that require large charges, since the diameter of the paper is limited to the diameter of the neck opening. Depending on the...

Look up videos of the Case Pro 100 on youtube. The crimper functions exactly the same, except the case pro has a motor attached by a linkage rather than a handle.
I believe that the folks who make...

I would think sticking tungsten carbide in a thin brass shell would rip up a lot of cases.

It does crimp 22LR cartridges. The picture is from "Ammunition Making". I would think a Case-Pro would be able to do the job if equipped with dies that have one groove to hold the rim and one ridge...

Most people use a micro-switch as a sensor when making a bullet feeder. China might make a smaller version that could work for primers. Or you could put a laser and IR sensor on opposing sides of a...
I bought some 123gr powder coated bullets to try in my 91/30. Unfortunately, there is not much data on 123gr bullets for the 54r and what I can find used Vihtavuori or Hodgdon powders, while the only...

I don't seeing this becoming very widespread. While it may work, simple inertia means it would have to work a lot better than brass, which is doubtful.

How much dross did you get with the 22 casings? I have buckets of them, but if the dross is too much I might as well scrap them.
