Help identifying die

[jason]

I recently acquired a couple of Lyman dies sets (the 310 type dies) in .270 and .243. Each set has the standard 310 sizing/decapping die as well as the seating die. They also each have another die (the one on the right) with them that is standard size with an rcbs style locking ring. The top is hollow and it fits in a standard size press. The only identifying marks on the die on the right is the caliber designation (i.e. .270 win).

Is this some type of body/bump die designed only to set the should back?

Thanks,

Jason

It could be a trim die or a lube die.

This might also be a die for the Truline Senior/ezy loader. in the center die postion one has to screw it in from the bottom as a regular die will not clear the top side.

That is the full length sizing die for Lyman's Ezy Loader press. It fits the rear, center position and has to be screwed in from the underside of the "ram". Therefore the odd shape as the toggle link has to clear it.

Thanks for the input - I knew someone here would know.
