Re: 7mm 180gr Berger VLD
1: Load them on the lands (provided your rifle even likes that) and use it as a single shot.
2: Load them to the max the magazine will allow for reliable feeding and develop your loads using the ladder method.
3: Get a Wyatts box extended magazine.
Into the lands is not always the best solution. With VLD's, it may be the norm but isnt always the case. Sometimes a barrel likes them a bit better if they jump.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
