I have called 4 times b4 I got my 50 bmg and they told me it was allowed.
RSO - closed Tuesday & Wednesday 300 Win Mag Is Just Fine only restricted caliber is 50 BMG
It open tomorrow
300mag should be fine. I think 100 yards is it. Thursday is usually an Open day. It is State-run, so it is probably open.
