Welcome to the board you will get a lot of different opinions here. This keeps it interesting. On my hunting rifle I use Simmons. I have one Leupold 12x on my 220 swift and I hate to say it but the Simmons on my 300 win mag puts it to shame in clarity and in light gathering. Maybe I should send it in to be looked at. Buy the way I never have to rezero the 300 it is always right where it is supposed to be.
