2018 OSA Events - Schedule (12 May 2018 version)

We are continuing to use the EventBrite online registration system for OSA events. The events are listed as "private" on Eventbrite, so you can't search for them. The links are published through our OSA Update emails and on the OSA Facebook page. They are also listed on the Schedule.

If you're new to OSA, make sure you email us for a copy of the OSA event Joining Instructions before you come. 

For MilCun courses and other events, email the registrar (as noted on the Schedule).

All participants at OSA events must have "liability insurance for all shooting activities" which is a benefit of membership in organizations such as the CFI, CSSA, NFA, OFAH, etc.



OSA focuses on three types of firearms:

  • Pistol (duty, service, operational),
  • Tactical/service rifle/carbine, and
  • Sniper/precision rifle.

For practices and clinics, the participants may use any equipment that they would like that's legal for the range. For competitions, in general terms, the equipment is required to be operationally oriented, either the kind of thing that is currently used by military or law enforcement, or that could reasonably be used by them. Anyone who wants to shoot a match with other equipment is welcome to shoot for honors only.

OSA Summer Events include a Pistol Scenario Match, Long-Range Rifle Practices, Operational Pistol Practices, Service Rifle Practice, Tactical Rifle Practice, an open 3-Gun Challenge, Reloading Clinic, Service Rifle Championship, Precision/Sniper Match, and a Tactical Rifle Championship.

At the request of our members who are planning to compete at NSCC, we've moved our Service Rifle Championship to mid-August. And the Precision/Sniper match is also in August, ahead of NSCC.

A favorite OSA event, the Canadian 3-Gun Championship (C3GC) is scheduled for Wednesday 01 August 2018. This is open to police, military, armed security, and emergency services personnel. Prior to this event, we're holding an open 3-Gun Challenge for civilians as well as those who qualify to shoot the C3GC.

The NSCC matches (pistol, service rifle and sniper/precision rifle) are currently planned to start 31 August 2018... but confirm this with the DCRA before you make your plans because we no longer control that schedule. You can enter any or all events. For details, watch the DCRA website www.dcra.ca.

MilCun Training Center is running our Enhanced Pistol Skills course in early July and then one of our most popular courses... the Enhanced (Long-Range) Rifle Skills course. Following that course, we're introducing the NEW 'Precision Rifle Series' weekend, specifically to support the 'Precision Rifle Series' competition in Meaford (and many places in the USA). In August, we run the Precision/Sniper Competition course, which develops your skills for the NSCC/ORA Precision/Sniper matches. For details, www.milcun.com.
