Need help sighting a new rimfire scope on my Marlin 60

[Niel4]

I just bought this 3- 9x32 Bushnell scope:

It mounts perfectly on my Marlin with the supplied hardware.....BUT how do I know if its lined up with barrel correctly?

I'm going to the range on Friday and want to be sure its sighted right or at least know that its in the "ball park" and that I can adjust it from there.

BTW, the Marlin was very accurate @ 20 yds with the OE sights. I didn't do too bad @ 35 either but i had trouble seeing well at the indoor range.
I was kinda shocked as it was only a $145 gun. Friday will be outside.

Any comments would be appreciated.

Unless you have see through mounts, and can adjust to your irons, your just gonna have to wing it. I like shooting at a silhoutte turned backwards, with a stick on bull, so I can see where I'm hitting.
