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

GBPR DMR (Designated Marksman Rifle) is a semi-auto rifle match that blends the time+ scoring format with precision rifle style stages. Targets distances from 100-700 yards with the majority of targets in the 200-450 yard range. Target sizes are practical and include: IPSC, 80% IPSC, 66% IPSC, 50% IPSC, 45% IPSC, Big Squares and Circles, animals etc.

This match is designed for the Gas Gun shooter using an off-the shelf rifle capable of ~1.5moa with factory match ammunition. The stages are “practical” and designed to be completed using a rifle and 1 bag. Movement is necessary in the stages which are designed to elevate your heart rate. The course of fire is written to accommodate both small frame and large frame cartridges and have a balance of time, shooting positions, target sizes and distances.
