After seeing the pics of the "possible" scope bases I'm doubly sure you made the right decision. Those screws (unless they are to be used for fitting purposes only) look like they were installed by an amateur.
Regarding the availability of 375 Ruger ammo in South Africa check with "Safari and Outdoors." They are a small retail chain (4 stores I believe) and perhaps the best source of hunting gear, firearms and ammo in SA. They have a web-site showing their inventory and a knowledgeable sales staff. We needed to pick up a few things for out hunt last August. Believe me, I was more than impressed with their extensive selection of ammo. If they do not carry the 375 Ruger and have no plans of getting it, I doubt that it will be available anywhere in SA. Let me know what you find out.
As an alternative, take a look a rifles in 9.3 x 74 and 9.3 x 62. Both have stellar reputations on African game and will do "most" of what a 375 can do. Either caliber could be substituted for the 375 in the three gun battery I previously mentioned.
I am sure those screws are used for fitting purposes . Herr Wiethaup is a very famous gunmaker in Germany . As for safari and outdoors I will check immediately. Thx again for the information..
