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

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

Equipment

OSA focuses on three types of firearms:

• Pistol,
• Hunting rifle, and
• Long rifle.

We look forward to the day when we can once again include service/tactical 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 Events - Descriptions

2025 Winter Events - January to March

OSA Snowshoe & Shoots - We meet at the driveway parking area at the MilCun Training Center and snowshoe in to the ranges. You must be fit enough and properly dressed to enjoy about 7 kms of cross-country snowshoeing. You will need to carry your firearm and ammo, as well as all personal kit (such as lunch and water) for the day. The winter events were suspended for 2025. We'll let you know if they resume.

2025 Spring Events - April to June

OSA Spring Events focus on clinics, and usually include the Pistol Clinic, Holster Course, and any other qualification clinics.

The Junior Hunter Program is an important part of the schedule. It's for Juniors and their mentors, with the 3 training days ending with a competition on National Range Day on the first Saturday in June.

OSA is adding a new event, the "One and Done". This will be offered as a trial in 2025, an event to test your long-range accuracy and knowledge of your equipment. More to follow. 

We'll continue to offer M-Class, 22 M-Class, MOS, and Running Boar. This year we're trying to have one of each of these every month. We'll also offer Historical Military Rifle (a clinic, then a practice, then a match). We're also organizing a Ballistics App clinic, a 22LR Field Hunting Practice, and an OSA First Aid course for MilCun range.

MilCun is offering a Pistol course in late May, plus a Wind Reading course in late June.

2025 Summer Events - July-August

MilCun Training Center is very busy in the spring with police courses and police agency custom courses and range rentals, so our civilian courses usually get started in July with the MilCun Enhanced Rifle Course. This year, MilCun will also be offering a Situational Awareness course in August... it's been in trials for three years, and it's now time to open it up to a larger audience.

The OSA Summer Events continue to include the usual M-Class, 22 M-Class, MOS, and Running Boar.

We'll also have two more events for military/historical rifle afficionados.

And we're planning an Urban Sniper practice, a Speed Challenge (pistol steel) practice, a Shotgun clinic and a 3-gun IDPA-style scenario day.

If we get our rights back, we will start up the clinics and practices that use the firearms we put in our closets back in the spring of 2020.

2025 Autumn Events - September- October

In late August, MilCun offers the Hunter Marksmanship Weekend course and OSA offers a 1-day match, The Hunters Challenge.

Autumn brings us to the championships for several disciplines: MOS, M-Class, 22LR M-Class, Operational Pistol, and Running Boar.
