Hello everyone, I have done a lot of research but the more I read it seems the more complicated things get. I am looking for a 1000 meters rifle and realize that there's many out there that will fill the bill but I am only 5'4" and weight 155lbs. This might limits my options somewhat. On top of that I have to think about throat erosion and such... basically barrel's life. Based on your experiences can you give my your opinions on which cartrige will best fit my need. By the way I prefer to roll my own than shoot factory ammos. Thanks in advance for any suggestions.
