I will be mounting a Leupold VX-II 3-9x40 on this shotgun which bases and mounts are best?

Game reaper ded nuts scope mounts model# 18200 they are cut away from the action of the gun and won't interfere with the ejection of shells. Very nice mount!

I put a warne two pc base and warne medium rings on the same Leupold scope. I could not get enough eye relief. I went to a warne tactical one pc base, I couldnt be happier.
I used a aluminum one pc base on my sons Savage 220f and it worked out well also but I prefer the all steel warne one pc base.

Don't have experience with the Savage but I have used the DNZ's and Warne rings.

Using the DNZ's on my X-Bolt and my T/C Omega and using the Warnes on a T/C Icon. Either mount would be a good choice. The DNZ's may save a little bit of weight.

Just purchased the EGW picatinny base part #2120 for my Savage 220F

Would have told you not to go with a pica-tinny base!!! I had one on my Sav. and it interfered with the ejection of shell, you may want to hold on to the receipt!

There are lots of great choices for bases out there. For rings, my favorite set I've used under $100 have been the Burris Signature Zee rings.

+1 for the Burris Zee rings

friend of mine has the picatinny base on his without any issues, also Savage also to use this base

I have the same egw 1 pc base on one of my Savage 220f it works perfectly well. When you eject shells do not baby the bolt, you have to work the bolt like you mean it.
I have one pc warne tactical on my other Savage and no problems with ejection.
