OSA 22LR M-Class Practice - 27 June 2026

We've taken OSA's popular M-Class bullseye shooting event and scaled it for .22LR.
OSA members, affiliates and guests are welcome to participate in .22LR sessions at the MilCun Training Center.
This practice will focus on .22LR M-class style competition training, with two or three shooters to each firing point. You'll need a scoped rifle with a bipod. You can use a rear bag. The distances will be 50, 100, 150, 200, and 300 meters. The targets will be bullseyes, with about a 2 MOA bull (and about a 1 MOA v-bull) at 50 and 100 meters, somewhat bigger at the longer ranges. The general rules are the same as in the OSA M-Class course of fire.
Ear protection is required, electronic ear defenders are recommended. Safety glasses are required.
If you have a low-power riflescope, a spotting scope is recommended.
$75.00 for non-members. $25.00 off for OSA members and $25.00 off for OSA affiliate members. If you're under 18, register as a junior.
Check in on the 100m range at 0830. You may be required to show your club membership card. Mandatory safety briefing starts at 0845. If you are not present for the safety briefing, you will not be able to participate.
