.577/450 Dies Mystery

[BlackPowderBurner]

I picked this up for a song last weekend, I know that one die is a re-sizer/de-capper and one is a bullet seater/crimp die. What is the third? It's just barely too small to take the case mouth so I'm guessing it might be a bullet sizing die? I'm a novice reloader so if anyone knows about the die and the maker that'd be a big help!

Thanks

It could be a powder compression die, a picture of the inside of the die would help.

Is it to flare the mouth to load lead bullets?

Bingo!! Without flaring the case mouth, you would almost certainly shave the bullet when seating. When seating, the flare is removed and the bullet slightly crimped in the case.

Here's a pic of the inside, I don't see why it'd be a mouth flaring die as the rim of the die isn't really formed into a pushing shape... also there's an adjustable knob on top that affects something inside.

If it's a straight wall case you need a flaring die and that's usually the 3rd die in a set. The last pic looks more like a seater die to me though.

With the concave looking end on the rod inside I think it would be a bullet seating die too.

Confirmed, it is a bullet seating die, though for what caliber I am not entirely sure... the lyman orange die box everything came in has a (homemade) label that says .577/450 Martini on half of it and .455 Webley on half. It seems to be just barely under the case neck size for 577/450. Could it be a webley seater? I'm really unfamiliar with this kinda thing
