This is not Hornady's first
rimless .38 Super case. They
used to manufacture the
rimless .38 TJ (Todd Jarrett)
cases which also had a special
extractor groove geometry.
Hornady does not make the
.38 TJ cases at present, though
Starline does.
The .38 Super Comp has been
around a while and is produced
by Starline. The Starline Super
Comp case is not truly rimless, and sports a
mini-rim. The rim measures 0.386-inch while
the case body is 0.380-inch. It's small, but it's
there. Hornady has duplicated this mini-rim in
their design. The extractor groove geometry of
the Hornady Super Comp and Starline cases
look the same.
Case capacity of the new Hornady case was
measured and compared to Starline cases.
I used the fine grained Accurate #5 powder
for this comparison. It has a bulk density of
0.990 grams per cubic centimeter, which is
nearly the same as water (water = 1.0 gram
/ cc). The Hornady case has slightly more
capacity than the Starline, holding 0.2-grains
more powder.

Case wall thickness
at various depths will
determine what weight/
length of bullets can be
used without excessive
bulging that would prevent
the round from fitting in the
chamber. The Hornady brass
will accept heavy bullets at
nominal overall lengths. I
was able to seat 160-grain
cast round nose bullets to
1.265-inch and a 170-grain Sierra FMJ .357
bullet to 1.280-inch without excess bulging of
the case wall. I did see a measurable bulge
when seating a 180-grain Nosler .357 JFP
bullet at 1.245-inch. It still fit in my chamber,
but it had a 0.002-inch bulge at the base of
the bullet.
The rimless .38 Super Comp is a distinct
improvement over the semi-rimmed
design, and Hornady's high quality cases
will be welcomed by .38 Super shooters
everywhere. The suggested retail price
is $80.35 per 200. A quick Google search
located the new Hornady brass at
MidwayUSA, Grafs, and Midsouth Shooters
at discounted prices.
