Gun sight-in land- Calgary area

[El Carnicero]

Hey all.
I know I'm late to the game with this, but where is a good spot to sight in the rifle around Calgary.
Most of my past spots are all gone now or have the rules changed in the area. So I'm looking for a new one for a quick afternoon run.

I'm not looking to steal anyone's sacred shooting spots, just somewhere to check the cross hairs.
The gun was good last year and brought in all my tags for me. I haven't touched the gun since then but just want to make sure i'm still good.

Any suggestions?
I'm in SE Calgary so the closer the better.
