Hi
I've owned three rifles in this chamber and to be honest thus far I've liked my Winchester safari the best. What some people don't know about the safari is that the bolt comes with a gas shield installed just like model 98 mausers (at least mine does). What I consider to be a problem with all winchesters is that they generally do not have any mechanism to prevent (in case of a case rupture) escaping gases to come shooting out the end of the bolt straight into your face. A major design flaw in my opinion. Thats why a gas shield is so important.
This little girl was made in 1964 (yes the first year of the design alteration). I have also found that winchester triggers are very simple and easy to adjust by simply tightening or loosening the spring which is held in place by a double lock nutt.
In addition this particular Safari Magnum has an internal box capacity of 5 rounds. I believe you will find that most production models these days max out at three rounds.
I would also like to point out that post 64 actions are stronger than the pre 64 actions and should be seriously considered in my opinion. There is absolutely NOTHING wrong with post 64 winchester model 70's. Controlled Feed is nice but not as important as everybody seems to think it is. They also have a very impressive claw extractor muck like a mauser action which makes cycling ammunition quite reliable.
It is also quite easy to find winchester model 70 parts and components to customize your rifle if the desire suits you (ie williams or lyman peep sights bolt right on). A used post 64 Model 70 safari Magnum in excellent condition (like the pics below) will go in the price range of $700 to $900.
Note: The front sight protector actually came off a model 98 military mauser. It fit perfectly.
As for the other models out there they are all quite nice. As for the CZ 550 Magnum models they are quite nice but I really do not like the single set trigger. I love the mauser action but single set triggers to not belong on a rifle designed to take out potentially dangerous game (my opinion). I believe in design simplicity. If you're thinking of going with CZ then I recommend you seriously consider the model 602 action instead.
