In my search for a magnum I would like your thoughts on the pro's and con's of each caliber & any rifle you feel is good in the field. I'll go for deer, boar & sometimes elk. I'm looking for the do all magnum. I have it down to the Winchester Model 70 Left hand. I have a Tikka and feel it is a great rifle however I feel that the 70 may just be a bit better I feel the trigger and the whole system is proven...not that any others are bad it just seems that the Model 70 is less prone to problems. I know the 70 LH is not in current production however I have a few lined up LNIB. Thanks in advance.
