I am looking to get a 20moa base for my Savage 10. Would like to keep the budget sub $100, BUT if I need to spend more I could be persuaded.

I am running Seekins Precision Rings (Aluminum). Rifle is a 6.5CM used for long range precision shooting.

I am interested in knowing if the added rigidity of a steel base has an effect on accuracy.

The bases I am considering are:
A) Steel
  1- Leupold MK4
  2- TPS xp
  3- Nightforce ($116) a little over budget

B) Aluminum
1- Seekins
2- Nightforce STD duty

I used a Nightforce steel base when I had a 700.  Idea is that the receiver is steel, so I wanted them expanding/contracting at the same rate during temperature changes.  Made sense in my head anyway. Dunno if there's scientific truth to it, but I suppose with accurate enough instruments it could be measured?

I have heard that in relation to rings/bases. According to YouTubes Rex aluminum rings on steel base is OK. Steel rings on aluminum base is bad.
