I have decided to build a 204 Ruger for varmint hunting out to 500 yards. I have heard some really good thing about the 204 and have heard it works well out to 500 yards when using the 39grn Blitzking. My shooting buddy uses a custom built 204 for his varmint hunting and it is deadly out to 500 yards. I will be using a Krieger 28" 1-12 twist barrel, Rem 700 Action, McMillan MBR Stock and Jewel Trigger topped with a Nightforce 3.5x15x56mm NXS scope. I would like to here what you guys think. I was also thinking about going with a 220 Swift which would allow me to reach out to around 600 yards with the 55grn V-Max. I am a varmint hunter and I like to shoot the varmint type bullets. If you have any suggestions, I would like to hear them.
