Re: Nosler Brass
It is normal for mouths to be dinged up a little from shipping and handling. The tiny lip on the outside isnt much to worry about unless youre using a very tight chamber. Nosler brass is about the best I have used for the 300 RUM. The remington brass is OK but the weight variences are bad and primer pockets get loose faster in remmy brass. I am not saying Nolser brass is awesome, just that it is better than the alternative. I have yet to find any excellent brass for the 300 RUM.
The things I did like about the Nosler brass was the weight to weight consistency and the fact that the flash holes are de-burred so that I dont have to do it.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, 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.
