first of all I want to introduce me (sorry but I don´t know if this is the correct place to do it), my name is Agustín and I´m from Patagonia (Argentina). I´m the 5th. generation of sheep farmers and I do live on a ranch in this remote and beautiful place. Because of the distances, not many shops on the area! haha (my ranch is 150 miles from the nearest town), and not to much people around with optics idea is the reason why I am looking for some help from you.
I bought a Tikka T3 Lite Stainless .308 (a very popular caliber in Argentina), and today I´ll send an email to a friend in USA asking for a Swarovski Z3 4-12 x 50 BRH Reticle (I spend some months per year USA for recreational holidays, but I am not going again till March). The idea is mostly punching paper at long distances, and some day hunting. I do not have the bases and rings yet, but the idea is to buy the Opti-Lock in Stainless steel finish to match exactly the Tikka Barrel. I read very good reviews about the quality of this rings.
The question is, which size of rings do I have to buy, MEDIUM or LOW? I was checking the Beretta web site and they have a table which indicate LOW rings for scopes up to 63mm for normal barrels and 55mm for bull barrels. But I read some posts about people who use the Medium ones with 50mm scopes "just in case" and to have a better parabola of correction? Is this true.
I understand the ones I need are: S130R924

I think the bases are the same for all the scopes: S132R916
