Needing a new mount for a scope coming my way. But I can't decide on which MOA mount to go with? The rifle is a semi-auto, 20" .308 platform. Thoughts on this? Initially, I was thinking 10 MOA to give a little help on distance but then I thought 0 MOA to help keep it for closer range stuff too and help the 50 objective clear the rail. My range expectations would be 600 yards or so. Maybe have fun and try to reach our further somedays but I realize my caliber choice and platform aren't ideal for true precision. I just want a fun gun to set on the bench and ping steel out at some distance.

The scope itself is 3-15x.

Thanks!
