Can anyone tell what the largest single stage press you can buy? Also which of the large press can you reloading 8-bore and 4-bore cartridge on without alot of modications?And last is there any sites that deal with buying good used presses?

I think the RCBS press sold for .50 BMG? Although no doubt Hornady do similar. You would need to view the makers websites for the exact dimension space above the shellholder to the top plate.

I think that for a 4 Bore you would not be able to accomodate it in the size hole that exists!

This one from Corbin is about the biggest one I've ever seen.

Those Corbins are pretty big.

Dillon sells one for .50BMG that's a monster, for $1000.

I also saw a web site where someone in Texas or Arizona sells a monster-sized progressive for around $1500.

I am guessing that any 'O' or 'H' press that handles 1.5x12 dies will handle elephant gun rounds. This is the forum to ask that question in.

As for used press reloading sites, it's called Ebay.

Any of the old Hollywoods that had a tie bar (late model Senior, Senior Turret, and Universal Super Turret w/ the 2-tie rods) can handle 1.5x12 dies and load BIG rounds. Dave Davidson of CH4D sells the dies and can offer press suggestions.

Senior Turret (also not mine)

"Old Western Scrounger" used to sell a massive press. I don't know if they still do (or even if they are still in business). Try an internet search.

RD: That's the company I was thinking of. Their site was active a couple months ago.

The biggest one I know of is the RCBS Big Max. It was made in the 80's. It weighs 23 pounds and was big enough for 50 BMG and swaging. I happen to have one that I swage 223 cases n to make a wildcat 9 MM pistol round.

It truly is a monster.

Here is a pretty big one:

Ponsness/Warren 50BMG press

RCBS & Hornady make the sme press, designed to reload the 50BMG. I woul dthink it could handle an 8bore, maybe not a 4bore though.
