January Antlerless-only Season
Only antlerless deer may be taken during
the January Antlerless-only season. Hunters
may participate in this season regardless of any
other deer license they have obtained. Hunting
is allowed on public land, and private land with
permission. Nonresidents are not eligible to
participate.
Shotguns, handguns, muzzleloaders, rifles
shooting straight walled cartridges, bows and
center-fire rifles may be used in the following
counties: Allamakee, Appanoose, Clayton and
Wayne (see map p. 6). See p. 31 for definitions of
legal method of take.
LEGAL METHOD OF TAKE
Archery: Longbows, recurve bows, and
compound bows shooting broadhead arrows
are permitted. No explosive or chemical devices
may be attached to the arrow or broadhead.
There are no minimum draw weights for bows
or minimum diameter for broadheads. Arrows
must be at least 18 inches long. Draw locks on
compound bows are legal.
Crossbows are not legal except that a
physically handicapped person, as defined on p.
12, may obtain a permit from the DNR to use a
crossbow. Applications are available at
www.iowadnr.gov/hunting - click on “Licenses
and Laws” and then on “License Applications,”
or by visiting the DNR central office or any of
the district offices (p. 45), or by calling the DNR
at 515-725-8200. Residents 70 and older may
obtain one Antlerless-only statewide crossbow
deer license. See p. 34 for details. Hunters
may not carry a handgun while hunting under
an archery tag, unless they have an unfilled
transportation tag for a season that allows
handguns or a valid permit to carry.
Shotguns: 10-, 12-, 16-, and 20-gauge shotguns
shooting single slugs only.
Muzzleloaders: Flintlock or percussion cap
muzzleloading rifles or muskets between .44 and
.775 caliber shooting single projectiles; muzzleloading
pistols .44 caliber or larger. Muzzleloaders
equipped with electronic ignition are not
allowed. There are no restrictions on in-line or
disk-type muzzleloaders. Riflescopes may also be
used.
Handguns/Rifles: Center-fire handguns .357
caliber or larger, and rifles shooting straight wall
ammunition with an expanding-type bullet (non
full metal jacket).
Deer hunters age 16 and under may not use
any handguns. Deer hunters ages 17 through
20 must be accompanied by a parent, guardian
or spouse who is at least 21 years old to use a
handgun.
Center-fire Rifles: Rifles .24 caliber or larger.
Allowable Straight-walled Cartridge Criteria:
¦¦ Center-fired straight-walled rimless cartridges
chambered for handgun use with bullets from
0.357” to 0.500” diameter and a case length
from 0.850” to 1.800.”
¦¦ Center-fired straight-walled rimmed cartridges
chambered for handgun use with bullets from
0.357” to 0.500” diameter with a case length
from 1.285” to 1.800.”
¦¦ The following cartridges do not meet the
above criteria, but are allowed: .444 Marlin, .375
Winchester and .45-70 Govt.
Then there is a chart on the next page which I can't get to display properly that shows both straight wall cartridges and centerfire rifle above .224 caliber for the January season yet only straight wall cartridges for all other seasons.
Whether this is a misprint or not I don't know, but didn't they allow this previously when they held the same season in the two southern lower tier of counties a few years ago?
