In recent years, Iowa has changed its regulations on straight-wall cartridge rifles for deer hunting, providing hunters with new, effective options for their hunts. This guide will cover the regulations and where and when straight-wall cartridge hunting is permitted in Iowa, as well as provide information on legal cartridges and rifles.

What is a Straight-Walled Cartridge?

A straight-walled cartridge is a type of firearm ammunition where the sides of the cartridge case do not taper or neck down. This means that the entire length of the case is of a uniform diameter, matching the diameter of the bullet. Historically, straight-walled cartridges were among the first types of metallic cartridges used in firearms. They are known for their simplicity in design and ease of manufacturing. 

Regulations for Straight-Wall Cartridge Hunting

The Iowa Department of Natural Resources (DNR) allows the use of straight-wall cartridge rifles during specific deer hunting seasons. Here are the key regulations:

  1. Permitted Seasons: Straight-wall cartridges can be used during the youth season, disabled hunter season, and both shotgun seasons.
  2. Legal Cartridges: Only certain straight-wall cartridges are allowed. These include center-fired straight-walled rimless and rimmed cartridges designed for handgun use, with bullets from 0.357″ to 0.500″ diameter and a case length from 0.850″ to 1.800″. See below for a non-comprehensive list of popular legal hunting cartridges.
  3. Legal Rifles: Only rifles capable of shooting the approved straight-wall cartridges are allowed. Hunters must ensure their rifles are compliant with the state’s specifications. Non-compliant rifles can lead to penalties, namely a two-year suspension of hunting privileges and a $250 fine.
  4. Expanding Bullets: Hunters must use expanding-type bullets, which are designed to expand upon impact, causing greater internal damage and ensuring a quicker, more humane kill.

Where and When Should These Cartridges 

Straight-wall cartridge hunting is permitted statewide in Iowa during the designated seasons. Hunters can take advantage of this regulation in various types of terrain, from dense woodlands to open fields.
