Type -R punches fit reloading presses and work with type -R dies. There are two basic types:
Internal Punches (fit inside the die body)
External Punches (slip into the press ram)
The kind of die must also be specified. A draw die can be
either for jackets or bullets. The punch for a draw die is
always an external type (fits the ram). But for jackets, the punch fits inside the jacket. For bullets, the punch is
full bore size and fits closely through the die.
Specific kinds of swage dies which have both internal and
external punches, and require that you specify the caliber, and in some cases, additional information.
CSW-1-R (core swage - specify diameter)
CS-1-R (core seater - specify diameter)
PF-1-R (point former - specify diameter)
LT-1-R (lead tip former - specify diameter)
Core seaters use an internal punch of a specific shape to
form the bullet base, and an external punch which either
fits into a specific jacket (depending on seating depth,
jacket taper, and wall thickness) or have a semi-wadcutter
shape of some type. Point formers use a spring-wire ejection
pin punch which fits the hole size in the top of the die for
the internal punch, and a full diameter external punch matching
the base type. Lead tip formers use an internal punch of a
given cavity shape and diameter, and an external punch which
both fits the diameter and has the desired base shape.
