Probably going to be too high at 100. If I were you, I'd ditch the tall see through rings and mount that scope as low as you can. I prefer the leupold one piece base but the old weaver bases are very popular too. Just be sure to get the longer one that hands of the front of the receiver about an inch for better scope placement. If you want to be able to use the factory irons, there are several quick release options that let you remove or install the scope with no tools.
I have the leupold quick release on my Marlin 45-70 and it works very well. Evidently though the clearance over the base is marginal. Some people say they can't see over the base on some guns to use their sights but I can use them on mine just fine. I believe it's Warne who makes a quick release that works off the Weaver base which is lower and looks darned nice too.
By the way, you will LOVE that 35 on deer. It is fast becoming my all time favorite. Just be sure to by ammo any time you find it because it is seasonal and only available in the fall in many areas. Remington core lock 200 grain is THE gold standard for bullet performance but the Hornady leverevolution is phenomenal and most people I know like it a lot.
You are correct about Warne sir. Try to get the one piece aluminum base. It gives better ring spacing than the 2 piece steel bases and is plenty strong enough. That with Warne low QD's and you're set
