OSA 3-Gun Scenario Practice-Match - 30 August 2026

A great way to hone your speed, accuracy, and handling skills in a dynamic situation.
The OSA 3-Gun Scenario Day is open to OSA members, OSA affiliate members and guests.
We’ll spend the day running through scenario-style matches (dry first, then live walk-throughs, then timed) with emphasis on analyzing the layout, balancing accuracy with speed, managing magazines, and handling skills.
The guns are:
• Pistol: any pistol, any sight, no classes. Ammo 300 rounds. You must be holster-qualified (OSA, IDPA, IPSC, agency).
• Rifle: any repeating rifle that can hold five shots minimum and can be quickly reloaded under time pressure. Centre-fire or .22. Fifty rounds of rifle ammunition required.
• Shotgun: any shotgun, any sights, no classes. Ammo 25 rounds of birdshot, 10 rounds of buckshot and 10 slugs.

Ammunition must be proven safe in each firearm. You must be competent with the operation of your firearms and have test-fired and zeroed your firearms before arriving at the event. If the ammo shows any signs of danger, you will be required to withdraw that ammo or firearm.
Electronic ear defenders and safety glasses are mandatory. Bring your own lunch and lots of drinking water.
$50.00 for non-members. $25.00 off for OSA members and OSA affiliates. Juniors (under 18) are free. OSA Volunteers who want to claim their discount on this event, please email [email protected].
