Junior Hunter Challenge - Was such a success, we have already been given very generous donations towards next year's prizes!

2024 Calendar will be built over the next several months - we already have some police agency bookings, and of course we'll soon be planning the dates for the Snowshoe & Shoots.

Courses of Fire for the OSA events will be updated and posted over the next few months. They are posted at the bottom of the events page.


Course of Fire Information

The Junior Hunter Challenge is complete for 2023. We'll be making some modifications for 2024 and will post on the Events page.

The M-Class course of fire has been updated (2023-07-04) to reflect the current practices.

Running Boar, Historical Military Rifle, Service Rifle (for bolt-action as well as other rifles), and our own "MOS" matches are also posted on the Events page. The MOS has been updated to reflect current practices, particularly the targets and taking the 'agony' timings out of the Agony Snap.


No Photos or Videos

We do not permit any photography at the MilCun Training Center. Our Range Officers will be watching for the use of any electronic image capture devices and will ask you to put such devices away. If you have questions about this policy, email OSA Secretary.
