Information on Bullet
Seating

FIG 62

FIG 63

FIG 64

The purpose of the seating die FIG 62 is

to insert the bullet into the case and to push
it down into the case the proper amount.

How far the bullet is pushed into the case

will determine the overall length (OAL).
Several factors go into determining the
proper OAL – such as, the maximum rec-
ommended OAL, listed in the reloading
manual, and the type of bullet being
loaded. The type of bullet can determine
the OAL in one of two ways. If the bullet
has what is called a cannelure, or crimping
groove (items A&B in FIG 63), this will
determine the proper OAL. If the bullet

you’re using doesn’t have a cannelure or a
crimping groove (item C in FIG 63), then
you’ll need to refer to your reloading manu-
al for the suggested OAL. The purpose of
the cannelure and crimping groove is to
secure the bullet by giving the mouth of the
case a place to go (without deforming the
bullet) when being crimped. When the bul-
let is properly seated, the mouth of the car-
tridge case should be near the top of the
cannelure/crimping groove FIG 64.

Refer to your reloading manual. Under

the section specified for the caliber you’re
loading, you’ll find a schematic of the car-
tridge. For example, .38 Special lists a max-
imum OAL of 1.55” (Lyman Reloading
Handbook). If you’re seating the bullet to
the cannelure/crimping groove, the OAL
should be well within the maximum OAL
listed, however, use a set of dial calipers to
check it. (Dial calipers are available from
Dillon Precision). If the bullet you’re using
doesn’t have a cannelure/crimping groove,
refer to the specific type of bullet you’re
using in the reloading manual. For example
– if you’re loading a 158gr 38sp JHP and it
doesn’t have a cannelure/ crimping groove,
use the suggested OAL of 1.480 (Lyman
Reloading Handbook).
