  • COSSA Park Central Oregon Shooting Sports Association (COSSA) Mile Marker 24 East of Bend on US 20 Bend, OR 97709 United States (map)

This match is designed for the Gas Gun shooter using an off-the shelf rifle capable of ~1.5moa with factory match ammunition. Optics are based on Division but are meant to allow entry level options to compete. Stages are meant to be completed using a rifle, bipod and 1 positional bag. Stages are intended to be “practical” in nature and applying a combination of stressors to improve the shooters ability to utilize their equipment in a controlled and safe environment. Movement is necessary in the stages which are designed to elevate your heart rate. Course of fire are written to accommodate both small frame and large frame cartridges and have a balance of time, shooting positions, target sizes and distances.

• Most calibers of an AR variant are allowed, subject to the same rules as the Precision Rifle Match. No steel core, velocity under 3100 fps.
• Rifle can be customized but the nature of the match is to be able to be competitive with “off the shelf” gear.
• Shooters should have a bipod and rear/support bag
• This is designed to be a one bag only match.
• Slings are not required but can be used.
• An optic that is a minimum of 6 power, 8-10 being the minimum ideal. Because this match has a precision element to it, we recommend an optic with MOA or Milliradian reticles versus a BDC (Ballistic Drop Compensator) reticle. The BDC reticle will work, and again, if your goal is to learn how to run your current gear better, then by all means feel free to go that direction. Open sights are discouraged due to low hit/success rate.

Min ammo required- 140 rds, max ammo required 200 rds.
